Hello! This is something I came up with since it's Valentine's Day so I thought why not write mini scenarios with BSD characters :)

It's basically what you got them and what they got you as a gift, I apologize if some are repetitive or similar, it was hard to think of completely unique gifts and reactions for everyone, but I tried my best! :)

I hope you will like it and enjoy! :D

CW/TW: none, fluff, maybe in Chuuya's part, him riding motorcycle if that's triggering for someone and a suggestive joke, in Gin's part there is a knife as a gift (i know how weird this sounds but bear with me), petnames and GN!reader, some characters might be OOC and if I forgot please anything let me know! :)

PS. I headcanon Tanizaki as a huge gamer; Tachihara as a kinder surprise egg lover and Sigma as a person who can draw really good, so bear with me🤗

*солнце моё - my sun; i thank deeply to my dear friend who helped me to think of a nickname and make it correct, you slay ily <3

Also I can do Fukuzawa, Lucy, Louisa, Fukuchi and Mori or other characters in second part if anyone wants them as well :D

I apologize for any mistakes in advance! :)

Happy Valentine's day everyone, remember to do something nice for yourself <3

Valentine's gifts || BSD characters x Reader

Decay of Angels

Nikolai Gogol

You were really excited about Nikolai and you spending Valentine's day together. You got everything ready, put on cute outfit and previously you bought him this beautiful, big painting of white birds flying in wide, blue sky and behind you wrote "As free as they are, they are still not alone. They still need shared nest and ground to rest. Thank you for being my nest and my ground." and you made him some piroshki that you've put on the table with few white candles around. You turned the picture towards the wall so he can't see it.

He finally came and you jumped on him into a huge hug.

"My, my someone missed me!" Nikolai said through sweet laughter.

"I have! Did you miss me?" you said happily, resting your head between his shoulder and neck.

"Of course darling!" he moved to give you a small kiss on your lips. You smiled and he put out a rose out of his coat, you smiled even more and rose suddenly sprayed water on your face. Nikolai's smile faded away in an instant.

"Oh no! That's a wrong one! Uh..uh..HOLD ON A SECOND!" he was nervous and he turned around as you giggled at his unusual clumsiness. He turned around after digging inside his coat and gave you a beautiful, fresh rose in your favorite color.

"It's beautiful! Thank you, love!" you smiled as you took rose out of his hand, kissing him on the cheek.

You turned around to put it in a vase.

"I don't think you want to put it there darling." Nikolai said softly and you turned around, slightly confused when you saw a huge wreath with probably 100 roses in a huge heart shape, missing only one in neatly done rows.

You gasped, it was absolutely huge and beautiful.

"Nikolai! This is...thank you so much!" you walked towards him, putting one last rose inside to complete the heart.

You gave him a strong hug, full of love and plenty of kisses on his cheeks.

He hugged you back and giggled at your reaction. You moved and looked at beautiful wreath one more time and put it down.

You took his hand to pull him over to piroshki and his eyes got wide in surprise and excitement.

"Oh! All of those for me?" he proclaimed, his voice filled with love and excitement and he took one of piroshki, immediately taking a bite and letting a huge satisfied sigh out, smile plastered all over his face.

"That's not all." you said and turned around the painting and Nikolai's eyes got wide once again, but this time more in deeply emotional manner. He started chewing slower and put down rest of his piroshki and came up to you to take a better look at the painting. He gently touched it as if he could break it.

"You have a message behind!" you giggled at him and he turned it around, taking it out of your hands to read. Once he read the message, you could swear he teared up. He got up, softly smiling at you, with little tears in corners of his eyes.

"You are right, they need nest and ground. However may I be a bird, you are my sky." he closed his eyes and pulled you into a huge hug that lasted for a very good time and kissed top of your head.

Fyodor Dostoevsky

Fyodor was never really fond of any type of holidays or special days in traditional way, until he met you. He waited for your return, put on some candles and bought you a silver necklace that had black agate stone placed on silver lineup and on that lineup it was carved "Cолнце моё".

You came home and went to hug him immediately, enjoying the atmosphere he made. He kissed you on the cheek and stroked your hair gently.

"Welcome home, darling. I have little something for you." he said softly and went to take a little, long, black leathered box to give you your gift. You opened it and saw this beautiful necklace and turned it around to see the carved, loving nickname. Your eyes widened and you feel warm.

"It's beautiful. I love it." you said in soft tone, Fyodor gently smiling at you.

"Let me put it on for you." he said and you gave him the necklace as he gently moved his fingers around your neck and put it on. You adjusted it a bit in the front, touching the black stone.

"This will go amazing with my outfit and our plans for tonight." you giggled and turned around to kiss Fyodor.

"What do you mean?" he asked a bit confused and you handed him tickets for a concert of classical music. He curiously took tickets and saw what were they for and smiled softly at you. He has been mentioning a lot how he is overworked and needed something just to let his mind relax.

"We better get ready then, love." he said and softly kissed you and both of you went to get ready, enjoying rest of your night in romantic, relaxed and loving atmosphere of the concert.

Sigma

Sigma was really nervous about this, he didn't know whole bunch of things about holidays and in general, he was new to everything but your love helped him discover and explore more of himself and the world. He wanted to make this day special and he was hoping he won't mess it up and that you will like his gift. He finally met up with you, you were holding some sort of bag, he hugged you softly, but you could feel he was nervous.

"Happy Valentine's day sweetheart..um, this is for you." he handed you what seemed like a notebook. It wasn't too thick or to thin and as you opened it you started tearing up. Notebook was filled with drawings of you, doing random things, probably when you would be with him in office and he would tell you he is doing 'paperwork' and you did something else to entertain yourself. You could also tell some were drawn from his memory only. Sigma was looking at you nervously as you flipped pages, eyes wider and wider each time.

"It's something I wanted to keep for myself, but..since it's a holiday, I thought you would like to have it." he said a bit hesitant since you weren't saying anything. You looked up at him with a huge smile on your face and closed the notebook to give him a huge hug. He was a bit shocked, but hugged you back.

"So, you like it?" he asked, soft smile on his face.

"I love it! I love you!" you said happily, hugging him thighter. Then you moved and out of bag pulled out a Sky Casino model with a note attached to the platform model was on. Sigma's eyes got wide as he took model in his hands, almost tearing up from beauty and shock. He noticed the note and took it as you took model inside your hands so he can read it.

"I know I often tell you how amazing you are, but I want you to always remember something. Sky Casino isn't what made you into a person you are, you are the person who made Sky Casino into what it is with your kind soul. I want you to always remember that when you look at this model. Happy Valentine's day, my beloved."

He read it and teared up at this point, putting the note on his heart. He gently smiled at you and put model down on the floor next to two of you so he could pull you into a hug.

"I can't bring myself to say anything else but that I love you too, Y/N."

Mushitaro Oguri

You were waiting for his return rather impatiently. You were slightly nervous about your gift, not knowning how will he react, but still, you hoped for the best. He finally arrived home carrying what seemed like his present for you and you went right into his body to hug him tightly.

"Happy Valentine's day, love." he said as he smiled at you and kissed your nose.

"Happy Valentine's day, Mushi. I missed you." you said as you hugged him for a bit longer and placed a kiss on his lips.

"I missed you too, darling." he smiled at you and gave you the bag. You were excited to see what he got you and quickly went to the living room and sat on the couch, unpacking it. You saw two small brown teddy bears, each had a bow tie, one just like Mushitaro's and other one was in your favorite one. They were holding hands and they were really fluffy. You pressed them on your chest as Mushitaro already came to see your reaction. You jumped into a hug with him and gently kissed his cheek.

"Do you like them? They are miniature of us." he smiled and you nodded.

"I love them. They are adorable! Thank you, Mushi." your eyes were bright and you kissed him on the lips. Then, you put little teddy bears down and went over for your gift. He could tell you were nervous as you handed him the wrapped box. Once he opened it he saw a game that basically was made as a crime mystery supposed to be solved.

"I know you dislike mystery, but I thought if..maybe we did it together, it will be more fun like that." you smiled shyly, not looking directly at him. This reminded him of his old friend which made him smile, but not only that. What also made him smile is that you knew the reason he disliked it and wanted to rewrite that into a good memory, something that he can actually enjoy and therefore heal. It was thoughtful, fun and really meaningful as silly as you thought your gift was.

"I love it. Let's solve it together." Mushitaro whispered as he pulled you into a hug.

"Really?" you whispered back.

"Really. It doesn't what do I do as long as it's with you, you make everything good. Thank you for that, Y/N." he smiled softly and placed a gentle kiss on your neck.

Port Mafia

Akutagawa Ryunosuke

You and Akutagawa weren't together, however after long thinking you finally decided to gift him something for Valentine's day. Obviously you were nervous, even though Akutagawa wasn't always unpleasant towards you, often times he was actually calm and well mannered, but still it was a huge thing. You made him a woven basket full of figs, his favorite teas he talked about to you and small antique painting. You were ready to go, giving yourself mental pat on the back and headed out. Little did you know.

Some time later you found Akutagawa taking his leave from Port mafia building, thankfully alone.

You nervously came up to him.

"Hello, are you busy?" you asked him, your tone low and almost cracking.

"Obviously not." Akutagawa responded in his usual tone.

"Ah right! Silly of me, um, okay, here you go." you handed out the basket, tilting your head down not to look at him.

He scanned it with his eyes and slowly took it out of your hands.

"What is this?" he asked, in his usual deep voice.

"A little something for Valentine's day. If you don't feel the same or dislike it or anything, feel free to do whatever you want with it." you barely smiled at him, your nerves taking best out of you.

"I shall leave now, see you tomorrow..or never again." you chuckled and almost started running away. Akutagawa took a look inside and smiled gently at his gift, as well as your reaction.

You came in your building, shaking and scolding yourself. However, once you reached the door you saw a bouquet of your favorite flowers and a small card on top. You were really curious about it, making you forget how nervous you were. You took a look at the card.

"I am not good with words, but I appreciate you. Hopefully, you understand. - Akutagawa"

You smiled at the note, he probably sneaked it in when you left because he was too prideful to ask anyone to do it for him and way too nervous to do it in person. You were still smiling and sent him a message making a deal for two of you to meet up and pick up where you left off.

Chuuya Nakahara

He took you on a evening ride on his motorcycle. He wasn't driving too fast, letting you enjoy the view of night lights as you held tightly around his waist.

"Where are we going?" you asked him excited and curious.

"Just a bit more patience, angel. We are almost there." he said and took a turn as you arrived to some sort of empty parking lot. You both got off the motorcycle and removed your helmets.

"What are we doing here? You are so perverted Chuu." you started giggling.

"The one who is perverted here are you, angel. I didn't have that in mind." he chuckled and took your hand as you walked towards garage doors.

"What is this, Chuu?" you asked him, not entirely sure what was he doing.

He opened the garage door and what you saw was a beautiful motorcycle that matches his. You gasped as your eyes widened.

"My gift for you, so we can do it together." Chuuya said and smiled at your reaction.

"This is insane Chuu, it's too much." you said still shocked. Indeed, Chuuya was extra but he loved you and wanted to show it as much as he humanly can.

You came up to him to hug him and kiss him and he returned it, smiling afterwards. You went to inspect the motorcycle, suddenly getting a thought.

"Um, Chuuya." you said as you were to reveal something obvious.

"What's up angel?" he asked as he came to inspect motorcycle with you.

"I don't have a licence and I don't know how to ride it." you said and looked at him with seriousness in your eyes. Chuuya stood there for a second as he was processing the information.

"Oh." he let out as he looked up at you.

"Shit. I completely forgot you need a licence for those." he said in a bit irritated voice.

"Excuse me? WERE YOU RIDING WITHOUT LICENCE NAKAHARA CHUUYA?" you yelled at him, shocked at his nonchalant attitude about that information.

"Being in Port Mafia has its benefits, you know? Not like cops will stop me. But that also means I can get you one as well." he smiled and stroked your hair.

"But I can't ride it." you said, looking up at him.

"I will teach you then. Easy as that." he smiled once more but noticed you were nervous and looking around shyly.

"What's wrong angel? You don't like it?" he asked concerned as he kept stroking your hair.

"No, no, it's not that. I love it, but..." you stopped your sentence to pull out a small hat chain you made for Chuuya that had an extenstion of mini hat, bottle and glass attached to it. You handed it to him. He looked at it and could feel himself melting inside.

"My gift is so small compared to yours and I made dinner and bought your favorite wine and made a bath for two us, but then you said this is urgent so I couldn't really pressure it.." you were saying looking down. Chuuya just moved your chin up and gave you a long, meaningful kiss. You blushed a little bit.

"It's absolutely amazing gift and I will wear it all the time. I love it and don't ever say anything you give me or do for me is small or less meaningful, angel." he smiled as he put your gift in his pocket.

"Let's head home and enjoy everything you prepared, then tomorrow we can start your lessons, sounds good?" he smiled and cupped your cheek with his hand. You nodded and hugged him thightly as he returned the hug, happier than he ever was.

Gin Akutagawa

Gin and you were fairly similar, but at the same time different, therefore complimenting each other perfectly. You worked under Black Lizard alongside with her. Two of you agreed to meet up after work to spend Valentine's day or rather evening together. Gin was waiting for you in place you both agreed on and you saw her in casual outfit which made you giggle because she was so beautiful.

You walked up to her and you gave her a kiss as she blushed a bit, more nervous than usual.

"You seem nervous babe, what's up?" you asked her, gently brushing her cheek with your fingers. She looked away and just pulled the box out of her bag and handed it out. You were curious and found her reaction really adorable. You took box out of her hands and opened it only to see one gorgeous knife in metallic red color with black handle that had your initials engraved.

You took it out, moving it a bit as light fell on it, making the color shine more. It was absolutely gorgeous.

"This is beautiful Gin, thank you so much!" you said in happy and excited voice and she opened her mouth lightly to say something when you pulled her into a hug. She hugged you back, resting her hands on your back and smiled.

"I have the same one. So we can match, you know?" she said as she was relieved you liked her gift.

"We really do think alike, don't we?" you smiled as you pulled away giving her your gift wrapped in baby pink paper.

You made her a new mask, it was in black color and on the inside you sewed small "I love you".

"That's so anytime you take it off you see it and so it can remind you of me." you smiled at her. Her eyes were full of love and she grabbed mask thighter, putting it on her chest.

"I love it. Thank you so much, I love you." she said gently and stroked your hair.

"I love you too darling and I have the same one, so another thing to match!" both of you giggled and hugged once again as you noticed people were staring at two of you, a bit scared and creeped out.

"Maybe you should put the knife back into the box, babe." Gin said through a laughter.

"Shit baby, you are right." you laughed and put knife back into the box, taking Gin's hand so two of you can go and enjoy rest of evening together.

Higuchi Ichiyō

You were having a lovely evening with Higuchi, eating amazing dinner two of you prepared together and chatted about everything and anything. Higuchi was always so lively, especially with you. You also brought her comfort no one else truly did and knew how to calm her down when she would go overboard with work and feel intense or pressured.

Gifts were common between two of you, little ways to show how you care and think of each other. Lately, you were both very busy so you didn't get much time to relax and spend time together, so this was a breath of fresh air for both of you.

"Okay, now for gifts!" Higuchi said as she was waiting for both of you to finish your dinner. You looked at her and she pushed a bag into your hands, sitting on her chair excited. You opened it and saw all sorts of candles - bigger, smaller, red, blue, yellow and few other colors, you also saw a bottle of some oil and love note. You unfolded the paper.

"I am forever thankful I've met you. You make my days brighter in ways only I can know which makes me feel really proud and special. You make feel calmness I never knew was possible to feel.

So, today I wanted to, hopefully, make you feel special and calm. I love you."

Your heart was melting and you got up from your chair and pulled Higuchi into a thight hug. She returned it, smiling into your neck.

"You always make feel special and calm, sunshine. Just existing next to you is more than enough for someone like me to feel like that." you whispered in her ear and pulled away in order to kiss her. You pulled away and slowly stroked her hair and she smiled at you, leaning in to kiss you one more time. It made you giggle and you gave her your gift. It was a small plastic sunshine frame that had picture of two of you inside. Higuchi's eyes widened and her cheeks got slightly red.

"Open it." you gestured to the back of the frame and she opened it to see a little note of you saying how she is your sunshine and how she should never forget that. She jumped on you which got you startled a bit and gave you a long, passionate kiss.

"Thank you, I will cherish this forever. Not only the photo, but you seeing me as your sunshine. I love you more than you know." she said after she pulled away and grabbed your hand to go to another room. She placed the photo on the nightstand next to the bed and gestured you to sit down. You listened, looking at her curiously.

"Give me a second, sweetheart." Higuchi said and went to grab an essential oil she got you which you learned when she came back.

"It's a lavender essential oil and I wanted to give you a massage so my little note comes to life." she smiled gently at you and you smiled back.

"Deal, but I will do same for you after." you said in soft voice and she nodded, smiling at you.

Oda Sakunosuke

This was a plan you had for some time now, but what a better chance to use than Valentine's day? You decided before Oda comes home that you will rearrange one room two of you barely used. It was supposed to be medium sized storage, but neither of you storaged anything really. So you went to work and rearranged it into Oda's new writing room. You put table and chair, made of beautiful oak and assembled few shelves on wall, as well as added some flowers and paintings to make it more comfortable and cozy. You added pens, papers, anything Oda would need for writing. You were really proud of your work. You wanted to surprise him.

Oda came home and called out for you, but didn't hear anything. He took his shoes off and called your name again with no answer. He went around the house, kitchen, bedroom, bathroom to look for you but he was met with disappointment each time.

"Over here!" you said in a bit higher voice and he could hear your giggles as he relaxed knowning you are safe and walked towards storage.

"What are you.."

"Surprise! It's a writing room for you. Happy Valentine's day darling!" you said as you jumped and stretched your arms out. Oda looked around, his face remained the same but deep inside he was shocked, touched and melted. He moved around, looking at all details you made and finally table ready with materials. He came up to you and lifted you up into a hug.

"You didn't have to do all this, you know?" he said as his hand was stroking back of your head as he was putting you down.

"You are right, but I wanted to! Do you like it?" you smiled at him.

"I absolutely adore it my love." he placed a kiss on your forehead.

"It happens I have little something for you as well." he said and took out a small box out of his pocket, handing it to you. You opened it and it was a golden ring and on the inside it had carved "My one & only."

You smiled, immediately putting it on one of your fingers. You looked up at Oda who was smiling back at you.

"I love it, thank you so much!" you exclaimed happily and jumped on him, your arms wrapping around his neck.

"You deserve everything, love, don't thank me at all." he whispered and kissed your cheek.

Ango Sakaguchi

You waited for Ango's return, he was as busy as always, overworking himself. Thankfully, he was able to get an evening off so you can spend it together. You prepared everything - dinner, ambience and a movie you will watch. You got him a neck pillow and a massager he can use on himself since you knew how much his back suffered all that work. He came home, drained and tired, but he was really happy to spend an evening with you. He took his shoes off and came up to you with a huge basket which caught your attention. It was covered with white net so you couldn't see what it was. You came up to him and gave him a big hug as he sighed out.

"It's good to be home for a change." he smiled as you looked up to him and then he leaned down to give you a kiss.

"This is for you, I hope you will like it." he pulled away and handed you the basket. You opened it up and it had literally everything related to self-care: oils, shower gel, shampoo, facemasks, body scrub, face roller, gua sha stones. It was beautiful. You smiled and put the basket down to hug him, your hands snaking around his waist.

"It's a reminder to take care of yourself. That's really important thing, you know Y/N?" he was stroking your hair and you looked up at him and his dark circles.

"That's a valuable lesson...coming from you!" you laughed at him and he softly smiled back at irony of his own words and actions.

"However! Good thing is that I had similar idea in mind when it comes to you." you gave him a wide smile and went over to give him his gift. It was in a bag so he opened it and saw neck pillow and massager suitable for self massage. He chuckled, looking softly at you.

"You know what? This is a looooot of products. I don't think I will be able to use them all on my own, so how about we share a self-care night?" you said looking up at him, earning a satisfied and relieved laugh from him.

"I can't see why not. I would love that, thank you, you are truly amazing, love." he said and you smiled back at him, two of you spending the relaxing, romantic night taking care of yourselves and each other.

Kouyou Ozaki

It was your first Valentine's day with Kouyou and two of you weren't together, however you did love her for quite some time now. Kouyou was very open about how she feels about Valentine's day and love in general. She was very hesitant and in a sense appalled by the idea of that holiday due to her experience with love. She was very vocal about how stupid she thinks it is and how people are just fools and if you "love" someone you love them every day making conclusion how people are shallow and dishonest with their feelings. You listened to her words and it made you nervous and prepared for a heartbreak, but you were ready to be heartbroken if that means she will know what you feel.

You made her a paper rose and as you would drag down the stalk of it - it would open up like it was blossoming and close back when you move it back up. You tied a little note on it and went to leave it at Kouyou's door in Port mafia. You arrived and knocked on her door, leaving the rose in front of them and went to hide, scared to see her face. She opened the door and looked down. She saw a paper rose and picked it up, noticing the note. Her face had confused expression the whole time until she read the note.

"I hope some day, just like this rose you will be able to open up and accept my love. If not mine, then someone else's, as long as you are happy. - Y/N"

She moved the rose and her eyes started watering as she was scared of all emotions that were coming out of her, thinking she burried them long time ago. She played with the rose, thinking, and you kept looking at her a bit confused. Was she happy, was she angry, was she moved by it? Did she feel the same or not?

"Come out, Y/N." Kouyou said as she closed her eyes, softly smiling. Your heart skipped a beat, but you couldn't trick Kouyou after all. You came to her, obviously nervous and on the edge. She turned her back and went into her room for a second and returned with something. She handed it to you and it was metal shaped and colored as her Golden Demon, attached to a chain. You took it, shocked and looked at her.

"I never thought I would be the one doing this. It's silly to be completely honest with you Y/N. I talked about this holiday so poorly, yet made that for you, hoping it will protect you from the distance." she looked at you.

"However, now I hope you will accept it and wear it as a confession of my feelings as well as to keep you safe and protected from any harm. Thank you for this rose and thank you for..awakening the hope and feelings inside me I thought were long lost." she stepped forward and pulled you into a kiss.

Armed Detective Agency

Dazai Osamu

You were dragging his hand, really excited.

"We can't miss this Osamu, walk faster!" you ordered him, earning a confused look and laughter from Dazai.

"Ah, ah, where are we rushing darling?" he said as his usual, teasing self.

"Not telling! Be patient, but hurry your ass up." you pulled him harder as you arrived to your destination. Dazai looked around, there were plenty of couples but you went to more isolated area.

"Now we wait." you proclaimed, holding his hand.

"For what exactly if I may ask?" Dazai looked at you confused as you stared into the sky.

"You may not! Shush it or you will miss it." you said squeezing his hand and he looked into direction you were looking at.

"Here comes yours!" you giggled, squeezing his hand harder.

Suddenly, with a loud sound, a firework appeared in shape of a heart and "I love you" in the middle, it was in bright pink color. Dazai stared at awe, this was one of the few times when he didn't know what to say. You looked at his face, it was so gentle and so genuine. His eyes got brighter and he squeezed your hand. It was a sight you could look at forever. Firework passed and his mouth were slightly opened as he looked at you, speechless.

"I customized it! I hoped you will like it and..." you couldn't finish your sentence as he pulled you in into a hug, squeezing you tightly. You hugged him back and started laughing a bit at sudeness of his reaction.

"And...I was hoping..this maybe gives you new perspective.." you continuned, muffled voice as your head was squeezed into his chest.

"No need to say anything else. I know." he squeezed you even thighter. You wanted to say something but you truly enjoyed this and it melted your heart.

He pulled away and looked into your eyes.

"That firework is how I feel when I am with you." he said in serious voice.

"You are so cheesy, Osamu." you laughed at him and gently slapped his chest. He smiled at you.

"I mean it. It's like I was reborn anytime I am with you." he gently brushed your cheek with his slender fingers.

"Stop it, I don't like when you talk like this." you said jokingly and he laughed.

"Now then.." he pulled something out of his pocket and quickly positioned it on your chest. You looked down and it was same opal stone he has. You touched it and looked at Dazai.

"Now we match. Also, this way, you see, our hearts are always connected." he smiled at you and touched his stone. He moved down and kissed you softly.

Then he pulled you into another hug.

"Also...sounds fireworks made were almost as loud as your farts, did you customize sounds too?" he pulled away, making fake amazed face.

"Dazai Osamu!" you punched his stomach.

"Ouch, ouch! You said you don't like when I am romantic, you don't like this either, it's so hard to satisfy you belladona!" he whined in dramatic voice.

"Maybe you just need to shut up, ever thought about that?" you laughed and pulled him into a kiss.

Kunikida Doppo

You were really excited about this day and your gift. Kunikida has been frowning lately because his notebook is near the end and from all work he had, he wasn't able to order new one. So you did it for him and it arrived just in time. You also wrote little note on the first page.

Now, you were walking to meet up with him at a local park as he said he wants to take you somewhere. Kunikida, on the other hand, was slightly nervous. Last year he took you in fancy restaurant and for most of your bigger celebrations. He wanted to switch it up this time out of his comfort zone. He wanted to take you in a game room so two of you can have some fun together and go out for an ice cream afterwards.

He wasn't sure how you will react to this and kind of regretted he didn't go for safer idea, but it is what it is now. He saw you coming and adjusted himself.

You spreaded your arms, running into his hug. He picked you up, returning the hug and kissed top of your head, then gave you a kiss on the lips.

"You seem really jumpy, what's the reason?" he asked with a soft smile.

"And you, Kunikida Doppo, seem really nervous, what's the reason?" you asked him playfully. Of course you would notice. He cleared his throat as his eyes gave away slight shock as confirmation of your question and wanted to speak when you cut him off suddenly.

"Maybe this will help you!" you said happily and handed him a notebook that was wrapped in paper with some animals. He took it and slowly started unwrapping it only to see his long desired notebook he wasn't able to order. He threw away the paper in trashcan and took another look, still in awe.

"Open it! There is something inside." you giggled.

He gave you a questioning look and opened it to see a dedication written from you. You wrote how you look up to him, how he inspires you every day to be a better person and as silly as his ideals can be at the times, they are still his and therefore deeply admired by you. You ended it by telling him to never change that fire in his heart and how you love him. He pushed his glasses up, closing the notebook and gently looking at you.

"You know, when I was writing who may my ideal partner be, I only had you in mind. I remember how I wished someone would be able to make me more flexible as a person or rather inspire me to see bigger picture and explore more of myself. Then you showed up and for that I am forever thankful, Y/N." he came closer to hug you and give you a kiss. You blushed at his words, unsure what to say.

You just hugged him thightly and thanked him as you pulled him into another kiss.

"You know, mister Carlylye said to send you a lot of greetings. Also, where are we going? Which resturant?" you asked him as you pulled away.

"I will make sure to send him letter tomorrow or give him a phone call if he isn't too busy. And as for where we are going, I thought about game room...if that's okay." he smiled, nervously as he waited for your reaction.

"Game room? Where did that come from?" you looked at him, a bit stunned by his plan.

"Well, I wanted to try something different, I guess. If you don't like it.."

you cut him off.

"I LOVE IT!" you gave him a big smile, putting all his worries away. He laughed a bit and you spent rest of your evening playing different games, winning or losing, it didn't matter. You had a lot of fun and enjoyed each other's company.

Atsushi Nakajima

You and Atsushi agreed to stay at home for Valentine's Day and have some alone time. You were finishing up chazuke you made for him as a treat for Valentine's. You came back to him and his face lit up. He was really excited and Valentine's Day with you felt surreal. He always had hard time to accept love from others given his inner turmoil. You taught him how to be more forgiving to himself, how to accept love and how to have love for himself. He still had long way to go, but he was better and every day brought new things.

"Thank you, Y/N! I really appreciate this." he said with a smile as he took bowl out of your hand and placed it in front of him.

"You are not going to eat it?" you asked him, a bit confused as he always literally dived in like there is no tomorrow. He shaked his head and got up to take something from the closet and turned around facing you.

It was a beautiful flower crown, you could tell it was a handmade. He came towards you and placed it on top of your head and smiled.

"I made it with tiny bit of help of Kyouka-chan!" he kept smiling. It truly melted your heart, anything he ever gave you was self made.

"I tried my best, I hope you like it." he said, blush covering his pale face.

"It's beautiful, you are so amazing! Thank you so much my love." you said and hugged him as he blushed, returning the hug.

"I have little something too!" you giggled and went to the other room to grab it. You came back and handed him a tiger plushie. He took it, inspecting fluffy tiger with his hands. He saw it had a small, loose collar that said "Mini Sushi".

"Mini..Sushi?" he looked at you.

"Like Mini Atsushi, but Sushi. Nickname." you smiled at him. His eyes got a bit wider and he smiled, hugging the plushie.

"Thank you, Y/N. You mean a lot to me and so does Sushi!" he smiled, genuine and warm.

"Remember anytime you are kind to him, you are also kind to yourself, Sushi." you said and went to hug him. He hugged you back as mini Sushi got squeezed between and Atsushi's eyes were soft, peaceful and loving as he understood meaning.

Ranpo Edogawa

Ranpo and you have been dating for a while now and this was your first Valentine's Day together. You knew what you will get him as soon as you started thinking of it. It was hard to surprise him and you knew that, but you hoped he will like your gift regardless. You got him a toy that looked like a machine, it was a bowl on top and on the plastic what was holding a bowl was actually few different games a person could play. Bowl had plenty of different candies inside and all you had to do is beat level in order to get it, it also had a refill which was perfect for Ranpo. You really hoped he will like it. On the other side, Ranpo understood concept of Valentine's Day, however he didn't get the point. Yosano scolded him that it's not a huge deal and gifting you something won't hurt. Ranpo did want to gift you something, that wasn't an issue, he just didn't know what. He was thinking and pouting and knew he was running out of time so he thought the best he could and got you a hat to match his. It's sweet and it also says how he loves your company when he solves crimes and mysteries.

You finally met up with each other, you came to the office as everyone else went to café and saw Ranpo there. He seemed a bit down, but you hoped your gift will cheer him up. You came to him and he got up, his face still unsatisfied. You looked at him and he just bumped his head into your chest.

"Ranpo? What's wrong?" you asked him, concerned.

"This is stupid." he said, his voice a bit sad.

"What is stupid?" you asked him, he still didn't look at you.

"This holiday. Yosano scolded me as if I didn't want to get you a gift which isn't true!" he said in annoyed voice and moved his head up facing you.

"Ranpo...you don't have to gift me anything. It's just a little holiday, if you just wished me happy Valentine's day, I will still be thankful." you were genuine.

"That's not the point." he scoffed.

"The point is, how do I tell you that I appreciate you and care for your company as well as that I enjoy when you go to solve cases with me and that you make me feel like I am not alone anymore and that I love you through a gift? And don't tell me to write a letter because I hate to do that." he looked at you. You looked at him surprised and started laughing.

"Oh my, well, just like that actually. You can tell me just like that." you smiled at him and he moved to get something out of his drawer and handed you the hat, same as his.

"Well, this hat is supposed to say it. You know, like we can match and...stuff." he looked away as you took hat out of his hand and put it on your head. He was still looking away, eyes closed when he suddenly felt a thight hug. He got surprised for a second, analysing your reaction but hugged you back.

"It's saying everything I need to know, don't worry. You also said all I needed to know." you said in soft voice.

"Really?" Ranpo asked as he wasn't really sure.

"I promise." you smiled at him, the smile he loved the most. You kissed his cheek and handed him your gift. He took it and inspected it for a while and then the biggest smile lit up his face.

"Thank you, Y/N. I really appreciate it. Now I can have more fun at work." he giggled and you laughed at him. He looked at you and put down the toy on his table and hugged you tightly.

"You look really cute with that hat, you know?" he whispered earning your smile.

"Happy Valentine's day, love." you said in soft voice.

"Happy Valentine's day, Y/N." he pulled away and you kissed, enjoying this lovely moment. Then Ranpo looked at the toy, bringing his hand closer and you noticed he just took one candy out.

"Hey! That's cheating!" you yelled at him and two of you continued this day laughing and enjoying.

Tanizaki Junchiro

Tanizaki and you made a deal to spend a day inside, nothing too fancy. You both liked comfort and cozy feeling of your own home and spending time together away from the crowds and loud city.

You arrived home with one small bag and Tanizaki came to you to greet you with a kiss.

"What took you so long? I missed you." Tanizaki said and pulled you into a hug.

"Sorry, sorry, I was picking out your gifts." you said and handed him the bag.

"Happy Valentine's day Chiro." you hugged him as he pulled out multiple games you bought, his face was shocked as those were really expensive and he gave you a look that was asking you "are you for real?" unable to say anything else.

"I save up, you know?" you elbowed him.

"Also, I thought we could play them together." you smiled at him and Tanizaki picked you up and turned to move you in the room. He placed you on the couch and started hugging and tickling you. You were laughing, trying to push him away.

"Stop, stop, why are you tickling me?" you were saying through laughter. Tanizaki got up and stopped tickling you.

"I am so happy! Thank you, those are so cool and we will have so much fun. Hold on!" he placed quick kiss on your head and came back in new pyjama and quickly sat next to you, giving you a small, blue bag. You gave him a questioning look, his face was light and his eyes sparkled, so you looked inside and saw another pyjama, matching his. Both were white and had little koalas hugging. You smiled and kissed Tanizaki.

"I will put it on right away." you said and went to change. Meanwhile, Tanizaki has set up one of the games, excited for your return. You came back and showed off how you look in new piece he got you.

"You look lovely, you are so cute Y/N!" he proclaimed as he stood up to come and hug you. He twirled you around and moved you to the set up where both of you sat down, ready to play.

"This is best Valentine's day I could ask for, thank you." he said and kissed you.

"Same goes for me, Chiro." you smiled at him and two of you spent rest of the day cozy, playing games and having fun.

Yosano Akiko

Yosano and you agreed to meet at your place and spend Valentine's day together. You prepared everything to be as romantic as possible. Yosano and you were together for some time and you wanted to make this day as special as possible. She was always kind and gentle with you even though you knew how she can get which made you melt and fall in love with her. You saw her as a woman who stood up for herself, yet treated her loved ones with the most care. Yosano could say same for you, you were the kindest, most precious person she has ever met and you loving her was an honor. That's how she felt and she wanted to make this day special for you as well.

She arrived with a small bag and you came to greet her, melting into her hug. She smiled softly and stroked your hair as you pulled away to look at her and give her a kiss.

"Someone is excited." she said lightheartedly and cupped your cheek with her soft hand.

"I am. I was so excited to see you today." you smiled at her and took her hand to move her and sit down together on the couch.

"Is that so?" she looked at you, saying teasingly.

"Yes." you looked at her full of love which made her melt at how genuine you were.

"I was excited to see you as well, my sweet Y/N." she kissed you and pulled away, gently placing a bag on your lap.

You looked at her and she nodded. You opened the bag and saw a notebook of some sort with covers in your favorite color. You opened the notebook and saw dry flowers glued on each page and next to each flower, there was a name of it as well as description of it.

"I picked all flowers that remind me of you." Yosano said as she looked at your lovestruck expression.

"This is beautiful. I truly don't know what to say, thank you so much, baby." you said as you looked up, Yosano's gentle gaze meeting yours.

"I am glad to hear that, Y/N." she smiled as you put aside the notebook, reaching under the table for a box. You handed it to her, a bit nervous. She smiled in order to calm you down and opened the box to see crystal figure in a shape of butterfly that was on lineup that said "You are an angel, my angel of everything that is good and kind."

She started tearing up, softly brushing her fingers on the sentence you designed. You waited for her to say something and she just put the figure on the table, not taking her eyes off of it and immediately pulling you into a hug.

You could feel your shoulder getting slightly wet and you hugged her thighter.

"Thank you. I love you." Yosano said through a whisper.

"I love you too." you smiled and stroked back of her head.

The Guild

Edgar Allan Poe

Two of you weren't a couple, however you were really good friends who crushed on each other. You wanted to hand your gift personally, hoping he feels the same way. You got ready and went out to head to his place in order to give him your gift. You were nervous and doubtful but if not now, then when? You just hoped you won't make this awkward between two of you or lose your friendship. It was a lot to ask for, you were aware, but still, Poe was reasonable so hopefully even if he doesn't feel the same he won't push you away. You also brought some treats for Karl.

As you walked, you felt someone watching or even following you and you turned around, but didn't see anyone who sticks out in crowd. You thought you were being paranoid and just kept walking. You arrived at more isolated area and you suddenly saw Karl jump in front of you. You backed away, startled at his sudden appearance.

"Did you smell the treats, little one?" you kneeled down to give him his treats and saw he was carrying something. It was a book and he dropped it in front of you as you handed him the treats. You opened the book as Karl munched satisfied next to you.

"I hope this doesn't ruin what we have. I have been in love with you for a very long time, Y/N. Therefore, I decided to write this for you. It contains all my feelings, like a personal diary, dedicated to you. If you don't feel the same - I completely understand. Feel free to throw it away or burn it, whatever you feel like doing, I just ask for this not to be the end of our friendship that I deeply cherish and hold dear in my heart. - E. A. Poe"

Your heart was beating so fast as you turned pages to read its and bits of what he has wrote. It was full of admiration of your personality, your beauty and time you spent together. You were shaking from how happy and excited you were. It felt surreal. You could scream right there but then Karl gently tapped your hand.

"To follow you?" you asked him and he started going in a direction behind you. You followed him and finally you saw Poe hidden behind a tree. He was literally biting his nails from anxiety and as he saw you, he got even more nervous, but was frozen in one place.

You came up to him, your face was red from excitement and your feelings for him and the fact he feels the same. You quickly gave him your gift which was small raccoon plushie that had a pocket. It had your love letter inside. Poe took it and unfolded it with clumsiness and started reading your confession. If his bangs weren't covering his eyes you would see how wide his eyes got, but shakiness of his hands told you all. Once he finished, he somehow got the strenght to look up at your face covered in impatience.

"Really?" he asked and you just came closer, pulling him into a kiss, he was shaken up at sudden movement but quickly adjusted and kissed you back.

And with this, you started your beautiful love story.

Hunting Dogs

Jouno Saigiku

Jouno and you agreed to spend Valentine's day as he was returning from a mission. You were really excited to see him and while he was away you thought about a gift that he will be able to use while away to think of you and one more practical gift that you picked out due to his complaining. He was always complaining how everyone were too loud, either they talked too out, breath too loud or, truth to be told, just exist too loud for his liking. He finally arrived and you didn't waste one second jumping into a hug and kissing him all over the face. He could sense your heart was about to explode from happiness which made him smile.

"Someone really missed me, huh?" he said in really low voice and hugged you thightly. You just nodded happily in his neck and he smiled.

"I missed you too." he slowly moved you away to give you a long, passionate kiss, not getting enough of you after being away so long. You pulled away and dragged him into a living room.

"Come faster, I want to give you my gifts." you giggled, Jouno smiled back at you, finding your excitement cute.

You quickly placed him on the couch and got two boxes. You gave him the first one.

"Okay, so this is more practical one, it's noise cancelling earbuds made specifically for you." you smiled as he took them out of box, his mouth slightly opened. He was inspecting them with his fingers.

"I tried all type of earbuds and trust me, none of them work, at least not with those bastards." he chuckled a bit and moved his head towards you.

"Just put them in Sai, don't be so skeptical." you told him and he listened, putting them in his ears and oddly enough, they seemed good.

You suddenly screamed and talked really loud how amazing it is and how you contacted his HQ to make them. He didn't hear you fully, he understood its and bits, he could still hear your heartbeat when he would really focus. You kept talking and he smiled, taking them out.

"I must give it to you, Y/N. They really do work." he said as he kept gentle smile on his face.

"I couldn't hear a word of your blabber." he teased you as you narrowed your eyebrows.

"Don't be mean now. I can also cut your ears off so you can't hear anything, you know?" you said in joking manner.

"I would love to see you try." he teased back and you smiled as you handed him second box.

"This one is more romantic, I think." you said, he could feel your muscles thighten a bit as you got nervous. He opened it and felt round, cold, thick but small piece of metal with a weirdish structure on top. He raised his eyebrow and pressed the structure and could feel 'I love you' beats being made in morse code. You were smiling nervously, not really sure how will he react. It was supposed to go in his pocket or anywhere truly, it was small but Jouno wouldn't be able to lose it given the fact it was Jouno. He pressed it once again and smiled.

"I think it's wonderful, Y/N." he smiled at you and you got even more flustered as he came closer to give you a gentle kiss.

Then, as he pulled away, he reached for his backpack, taking out a small box. He handed it to you and you opened it for your eyes to meet an earring, same as Jouno's and really pretty bracelet that had a little sword attached to it. You slowly took them out and put on an earring and bracelet as you looked at Jouno, who was smiling softly at you.

"Originally, I wanted to give you my earring, however the one you are wearing was handmade by some man I helped on the mission, I thought it would be nice to match. As for the bracelet, that little sword is a heartbeat measurment and it allows me to sense yours with this little thing.." he pulled out some sort of little machine.

"I wanted to be able to listen to your heartbeats before sleep, since they put me at ease and to track your mood during the day." he smiled at you.

You didn't say anything else, just quickly pulled him into a hug and he smiled, hugging you back thightly.

Tecchou Suehiro

Tecchou and you woke up next to each other, cuddling and whispering sweet nothings. You slowly got up and started your day, showering together and got dressed up, moving on to make some breakfast. You made pancakes with strawberry and nutella and also made your morning tea and coffee. It was overall nice, peaceful and romantic morning.

"You know, those pancakes would go great with ketchup and strawberry." Tecchou said, completely nonchalant.

"Excuse you?" you said as you laughed at him.

"I knew your taste was...special, to say at least but we won't make pancakes with ketchup and strawberries." you continued as Tecchou looked away, slightly disappointed. You laughed at him and got up to bring your gifts for him.

"Don't pout you grown baby. Maybe this will cheer you up." you said as you sat down, handing him your gift with a smile. He curiously took it and opened the bag and saw pair of gloves as well as some box in royal blue color. He took them out carefully, inspecting them.

"Gloves are for you since I noticed you hurt your hands a lot, so I thought to get you those to protect them." you smiled but Tecchou was silent, not looking at you. He opened the box, which made you nervous and he saw a lot of folded papers inside. He unfolded few papers and you were almost digging your fingernails into your skin because of his lack of reaction. On papers you wrote what you love, admire and appreciate about him and many other sweet, loving things. He folded papers back, gently placing them in the box and covering it with the lid. You were sweating at this point, he didn't look at you once. He closed his eyes and gentle, angelic smile covered his face as he stood up and came over to you and kneeled down, resting his head on your lap, his hands hugging your hips. You were a bit shocked.

"What did I do to deserve you, angel?" Tecchou said in soft, genuine voice. You were still slightly frozen, but his reaction made you smile and you placed your hand on top of his head to play with his hair.

"Just by being you, my love." you answered him in gentle tone and he suddenly looked up at you, his eyes big and full of love. He moved up to you and gave you a soft kiss on the lips. You smiled and then he kissed your forehead and stood up completely and went to bring you his gift.

He came back and gave you a bag that had teddy bear holding a heart on it. You smiled and he smiled back at you. You opened it and saw a little plushie of a dog that had Hunting Dog's uniform. You melted, but you couldn't ignore the smell of his cologne that was really strong. He noticed.

"Jouno said you will be able to smell it for next 10 years, so I think that's good." he said innocently not realizing the amount he sprayed. It still made your heart warm and you hugged the plushie thightly.

"Now you have someone to keep you company when I am away." he smiled and you got up plastering a soft kiss on his cheek and lips.

"Thank you my love, it's lovely." you said to him and you spent rest of your day enjoying each other's company.

Tachihara Michizō

You were waiting for Tachihara in the centre of the city so you can go home together. You were slightly annoyed because it was so crowded but then you finally saw him. He had a huge smile on his face and waving to get your attention. You waved back as he came up to you, picking you up and looking at your face with a huge smile.

"How is my favorite bastard doing?" he said lightheartedly and you laughed, gently slapping his arm. He put you down and pulled you in a loving kiss.

"Let's go. Do you want me to carry your backpack?" you asked genuinely.

"Hah! As if you can carry it, I will be fine." he chuckled and took your hand, two of you walking home and chatting about his missions and stuff happening in your lives while you were away. You already left your gift on the table, hoping he will be surprised. It was a huge chocolate cake that had 10 kinder eggs around.

As you finally arrived home, you quickly left him behind to wait next to the cake.

"Why are you rushing so..." Tachihara wanted to ask, but as soon as he saw the cake, his mouth opened wide. He was shocked and saw you standing next to it, proudly smiling. He took few steps forward as he looked at the cake, mouth and eyes wide open.

"You didn't!" he proclaimed excitedly as he quickly took one of the kinder eggs to inspect it.

"I did!" you smiled at him and he put the egg down and pulled you into a hug.

"You truly are a little bastard, is this why you were so excited?" he smiled and you nodded at him. He hugged you thightly and gave you a kiss on the lips making you giggle.

"Well then, I guess I can wait a bit before I open them." he smiled and went to his backpack, taking out big, red cotton bag. He gave it to you and it was really heavy. You looked at him, questioning expression in your eyes.

"You might want to open in on the couch." he said as he rubbed back of his head. You went to the couch, turning the bag around and you saw plenty of rocks and shiny crystals dropping out of it. There were all colors - from black, white, purple, brown, grey, mixed and all type of crystals - amethyst, rose quartz and others. You looked at awe and started inspecting them with your fingers.

"I took every rock and crystal that reminded me of you, I hope you like them." he said slightly nervous because he wasn't the best at expressing his emotions.

"I love them! You are such a sweetheart, you know?" you said and quickly jumped to hug him. You looked up at him and he smiled, kissing your forehead.

"I am glad to hear that baby, now can you help me open my kinder eggs, please?" he said and you could tell he was impatient and excited. You nodded, happy and enjoying the lovely moment with him. You spent rest of your day catching up, cuddling and opening kinder eggs that Tachihara was insanely worked up about. It was truly an amazing day.

Special mentions

Yokomizo

You went to drugstore to buy things for bath that you had in mind for Yokomizo. You just wanted him to relax and enjoy this day, taking a break from work and writing. You bought everything you need and as you entered your garden, you picked up roses because it would be a nice touch. You arrived home and greeted Yokomizo who seemed to be working so you didn't want to bother him and immediately went to the bathroom, preparing a bath. You put on candles, burned sticks in smell of lavander, filled the tub and put in gel that smelled like a fresh breeze carrying nature and its smells. It was full of bubbles and beautiful foam so you dropped rose petals on top, adding to the athmosphere. You turned off the lights and it truly looked enchating, healing and romantic. You also made sure to leave some snacks behind and a book so he can relax and enjoy.

You came to him, who seemed to be finishing his work.

"Honey, I made you a bubble bath." you said shyly, hoping he will like it. Yokomizo smiled and stood up, taking few steps towards you.

"Did you now?" he smiled and gently brushed your cheek with his thumb. You nodded and he looked at you lovingly, placing a kiss on your forehead.

"Thank you my love. Not to be bothersome, but could you please clean up my desk and then join me afterwards?" he said in apologetic tone, but still sounded confident for some reason. You nodded again, earning his smile and he stroked your cheek one more time as he went to the bathroom.

You went to his table and saw a big paper.

It said "All my peace, love and reason is you." written in calligraphy. Your heart felt warm, your face covered in wide smile as you quickly went to join Yokomizo in the bathroom. Two of you spent rest of your day in romantic, relaxing and loving manner truly enjoying each other.

The End :)

Thank you for reading and I truly hope you enjoyed this!

Thank you for all love you gave me so far, it truly means a lot and I deeply appreciate it :)<3

Kisses on the forehead for everyone hehe

Microfluidic Preparation of Microencapsulated Phase Change Materials with Polyurea/Polymethyl Methacrylate Shell for Thermal Energy Storage

Authored by: Jun Li

Abstract

A facile three-step approach was presented to prepare microencapsulated phase change materials (MEPCMs) with n-octadecane as core and polyurea/polymethyl methacrylate (PUA/PMMA) as shell. First, a droplet-based microfluidic technique was introduced to generate microdroplets of n-octadecane with controllable size. Then, an interfacial polymerization technique was employed to form a protective shell of PUA on microdroplets to prevent them from collapse and coalescence. Finally, an in-situ polymerization technique was adopted to form a compact shell of PMMA inside the PUA shell to improve the thermal performance of MEPCMs. The MEPCMs with PUA/PMMA double-layered shell exhibited high monodispersed in size and sphericity, good phase-change performance, and enhanced thermal stability and durability for thermal energy storage applications.

Introduction

MEPCMs are small composite particles of phase change material (PCM) with stable core–shell structure [1]. The shell of MEPCMs can isolate the PCM core from the outside environment and ensure the safety and reliability of MEPCMs. MEPCMs as thermal energy storage (TES) material can modulate the temperature by cyclically storing and releasing latent heat through phase transition, and thus have potentially wide-ranging applications in smart thermo-regulated textiles [2], electronic and electrical appliances [3], battery-electrified vehicles [4], and intelligent buildings [5]. It is noted that MEPCMs fabricated by conventional methods, such as in-situ polymerization, interfacial polymerization, and mini emulsion polymerization, often feature nonuniform sizes and irregular shapes because the emulsion procedure is usually triggered by mechanical stirring or ultrasonic vibration [1,6,7]. The polydispersity of MEPCMs is probably the reason for inconsistency and unrepeatability of current studies on TES applications [8-10]. Considering that controllable size and morphology is an important prerequisite for stabilizing the performance of MEPCMs, a novel droplet-based microfluidic technique was employed in the study instead of mechanical emulsification. Droplet-based microfluidics can realize the massive production of monodisperse droplets and easy control of each droplet [11,12]. Interfacial and in-situ polymerization techniques were combined to from a double-layer polymer shell on PCM droplets. The former was adopted for forming a thin layer (PUA) instantly on PCM droplets to prevent collision and coalesce, and the latter for synthesizing a compact and stiff shell (PMMA) by using the stable droplets as templates to enhance thermal performance for TES. The resultant MEPCMs with PUA/PMMA shell were expected to have good morphology and stable performance.

Materials and Methods

The co-flow microfluidic setup used to generate the MEPCMs with controllable structure and size is displayed in Figure 1. The dispersed and continuous phases were injected into the glass capillaries using the syringe pumps, and the corresponding flow rates were set at 500 μL/min and 20 μL/min, respectively. The dispersed PCM phase was a mixture solution consisting of 2,4-toluene diisocyanate (TDI, 2.5 wt.%), methyl methacrylate (MMA), and 2,2-azobisisobutyronitrile (AIBN) in n-octadecane. The continuous phase was an aqueous solution consisting of tetraethylenepentamine (TEPA, 5.0 wt.%) and sodium dodecyl sulfate (SDS, 5.0 wt.%) in deionized water. All materials were purchased from Sigma-Aldrich and used as received, Singapore and used as received. The mass concentration of MAA monomers ranged from 30 wt.% to 45 wt.%, and the mass ratio of MMA to AIBN used to induce the polyreaction of MMA monomers was set at 20.

The MEPCM preparation involved three steps: the formation of PCM microdroplets, the formation of MEPCMs with PUA shell, and the formation of MEPCMs with PUA/PMMA shell. Firstly, the dispersed phase traveled to the capillary orifice (40μm) and broke into the spherical PCM microdroplets by a shear force of continuous phase. The precise flow control of the continuous and dispersed phases facilitated the production of monodisperse microdroplets. Secondly, the shell of PUA was formed on the PCM microdroplets when they migrated in the direction of the continuous phase. The TDI in the microdroplets could react with the TEPA in the continuous phase to form PUA through interfacial polymerization. The reaction was terminated once the PUA polymer completely encapsulated the PCM microdroplets. Finally, the MEPCMs with PUA shell were collected in a vial of deionized water and placed in a warm-box for 8 h at 80°C to form the second layer of PMMA inside the PUA shell through the in situ polymerization of MMA monomers. The resultant MEPCMs with double-layered shell were washed with deionized water and dried at 45°C for 12 h to remove the water for performance testing.

The morphology of the MEPCMs with PUA/PMMA shell was measured using a field-emission scanning electron microscopy (SEM, Sigma 300, ZEISS, Germany), the chemical structure was measured using a fourier transformation infrared spectroscope (FTIR, 8400S, Shimadzu Corp., Japan), and the thermal stability was evaluated using a thermogravimetric analyzer (TGA Q50, TA Instruments, USA). The phase change performance of the MEPCMs was measured using a differential scanning calorimeter (DSC 3500, Netzsch, Germany). The measurements were carried out in the temperature range of 0°C-50°C at a heating/cooling rate of 5oC/min. The encapsulation efficiency (Een=(ΔHm,MEPCM/ΔHm,PCM)×100%), the energy storage efficiency (Ees=(ΔHm,MEPCM+ΔHf,MEPCM)/ (ΔHm,PCM+ΔHf,PCM)×100%), and the thermal storage capability (Ces=(Ees/Een)×100%) of the MEPCMs could be calculated from the melting (ΔHm) and freezing(ΔHf) enthalpies obtained from DSC scans [13,14]. The prepared MEPCMs were also subjected to 200 cycles of heating and cooling in DSC to evaluate thermal durability.

Results and Discussion

Figure 2a shows the FTIR spectra of the n-octadecane and the MEPCMs with PUA/PMMA shell. The MEPCMs presented three additional peaks compared to the n-octadecane. The peaks at 1649 and 1558 cm-1 were assigned to the carbamide group of PUA, and the peak at 1732cm-1 was assigned to the ester carbonyl group of PMMA, suggesting that the n-octadecane was successfully encapsulated by the PUA/PMMA shell. A typical elemental spectrum of the MEPCMs was given in Figure 2b, and the presence of carbon, oxygen and nitrogen elements also confirmed the microencapsulation of n-octadecane with PUA and PMMA as shells. Figure 2c shows the TGA curves of the pure n-octadecane and the MEPCMs formed at different MMA concentrations. The thermal degradation of n-octadecane exhibited one stage with the initial weight-loss temperature (T0.05) of around 131°C. The decomposition of n-octadecane went quickly and stopped at around 206oC. The prepared MEPCMs degraded in two stages: the first stage was the weight-loss of n-octadecane in the temperature range of 150-225oC, and the second stage showed the decomposition of polymer shell in the temperature range of 225- 450oC. Apparently, the decomposition of n-octadecane core was successfully delayed by the PUA/PMMA shell, indicating that the MEPCMs achieved good thermal stability.

The SEM micrographs of the MEPCMs prepared at different MMA concentrations were displayed in Figure 3a. The MEPCMs had a regular spherical shape and a uniform size distribution around 100μm, demonstrating that the first shell of PUA could stabilize and prevent the PCM microdroplets from breakup in forming the second shell of PMMA. The polydispersity index (PDI) was used to characterize the size distribution of the MEPCMs. PDI is a number calculated from σ/da, where da is the average size, and σ is the standard deviation. In the study, the maximum value of PDI did not exceed 0.03, indicating that highly monodispersed MEPCMs was achieved via the droplet-based microfluidic approach. Figure 3b shows the SEM micrographs of the MEPCMs subjected to thermal cycling test consisting of 200 cycles between 0oC and 50oC. The MEPCMs formed at 40 wt.% and 45 wt.% maintained good spherical shape and compact surface, whereas for those formed at 30 wt.% and 35 wt.%, broken MEPCMs with irregular shapes were observed, namely, the thin shell couldn’t protect the n-octadecane from leakage anymore. In short, the MEPCMs with PUA/PMMA shell could achieve long-term thermal durability when the MMA concentration was higher than 40 wt.%.

Figure 4 presents the DSC curves of MEPCMs formed at different MMA concentrations. For all MEPCMs, the onset temperatures of freezing (Tf) were approximately equal to those of melting (Tm), implying that the PMMA shell could serve as nucleation substrate to promote phase change of n-octadecane without supercooling (ΔT=Tm-Tf). Supercooling elimination of MEPCMs is beneficial for reducing the energy consumption and making the TES system efficient [15-17]. With increasing MMA concentration, the phasechange enthalpies of MEPCMs decreased, and the encapsulation efficiency (Een) reduced from 77.5% to 56.1%. The energy storage efficiencies (Ees) of MEPCMs were close to the encapsulation efficiencies, suggesting that n-octadecane core in MEPCMs could freeze completely and release almost all of latent heat in the subsequent melting. The calculation of thermal storage capability (Ces≥98.5%) further verified that n-octadecane was well encapsulated by polymer shell and could fully exert its function during the phase-change cycle [14]. Figure 4 also shows the DSC curves of MEPCMs after 200 phase-change cycles. The MEPMCs formed at 40 wt.% and 45 wt.% exhibited little temperature and enthalpy changes in exothermic and endothermic peaks, whereas significant changes appeared in those formed at 30 wt.% and 35 wt.%. It is indicated that the MEPCMs with encapsulation efficiencies of 69.6% and 56.1% possessed good energy storage and release performance for TES.

Conclusion

Microencapsulated n-octadecane with PUA/PMMA doublelayered shell were successfully fabricated by combing the microfluidic emulsification, interfacial and in-situ polymerization techniques. SEM results verified that highly monodisperse MEPCMs with regular spherical shape were attained, the polydispersity index of which was lower than 0.03. TGA measurements showed that the compact PUA/PMMA shell could protect the MEPCMs from thermal decomposition. DSC analysis confirmed that no supercooling was required for the phase change of MEPCMs, and good thermal storage capacities higher than 98.5% were achieved. Thermal cycling tests indicated that the MEPCMs with encapsulation efficiency up to 70% had long-term thermal durability. The advanced MEPCMs with PUA/PMMA shell possess good potentials for TES purposes, such as intelligent textiles, solar cells, and building materials.

oc is back on her bullshit!!! miss out and about im gonna forget about you!! im so sorry for this part actually. descriptions of oc sleeping with someone who is not jaykay (warning!! infidelity but not really). suppressed feelings on jks side. chayoung is still Suspicious. everyone is now mildly shitty actually. roughly 2k. listen to not gonna cry by emma steikbakken and stranger by tove lo.

titled — fuel to the fire

It's been three days since you last spoke to Jeongguk (and four weeks since your break-up). Not about your relationship or the horrendous state your sudden break-up left you in, or about the fact that Jeongguk had moved on before your heart had even registered the cracks he'd left in his wake. No, not that – none of the actual life changing important stuff, only him briefly mentioning that you needed to hand in your event proposal for the student committee before the deadline approached. It was unbelievably strange to watch the person you'd basically surgically attached to your being behave like a complete stranger. It didn't help that he didn't seemed unfazed approaching you, while you on the other hand actively avoided him and all the usual corners of campus where he liked to lurk (which sucked because those corners were some of your favourites places too). But there he was, ambling to you with an ease that made your gut violently twist, acrid bile slithering up your throat.

He'd spoken so freely, the sound of your name on his tongue a brand on your skin. You'd frozen, heart a wild animal locked in your chest, before you could summon the mettle to look him in the face.

The first thing you noted was that his hair was no longer long. Dark locks cropped short around his ears now and casually gelled back, idle strands playfully framing his face. His features are what you settled on next, eager eyes remapping the sharp slope of his nose, easily identifying the sneaky dimple on his cheek begging to burst free and then shifting down to the dark mark right below his soft pink lips.

Your first instinct was to pull him into your arms but they were frozen, glued to the table beneath you before that blinding rage rose it's head, sparking through your veins the longer you looked at him.

He didn't even seem to realise it, rattling off the list of things you needed to email him for the spring scavenger hunt or else the event could be cancelled (which sucked because that was an idea you had created with Jeongguk and now you were stuck carrying the bulk of the event alone).

Your replies had been curt, blunt as they left your lips before you'd pointedly turned away. Maybe if you had looked a little longer you would detected the lingering gaze he granted your features, how he shuffled on his feet, unsure and hesitant, words on his tongue longing to be released. Eventually he had swallowed him down, mumbled a quick goodbye and wandered off, the hands shoved in the pockets of his baggy jeans aching to hold yours again.

You, however, didn't miss the muffled giggles of girls he passed on his way out, a sick icky feeling clogging your throat. You didn't mind the fan girls when you were dating because you knew Jeongguk was yours and yours alone. But now? When he'd moved on not even a weak after your break-up you didn't know how to feel. Jealous, maybe. Furious, absolutely. For a second, you considered throwing your mini stapler at their huddled heads, weighing the odds of possibly going to jail for assault. But there was no reason to truly justify that reaction, not when Jeongguk was single and apparently available for everyone. But did that feeling still brew inside of you? Turning into something black and vile and vengeful? Perhaps.

And maybe that's why you're here now, the body of some boy pressing against yours, your bare back prickling as the night wind grazes against it. The dress you'd plucked from your closet was criminal, clinging to the dips and rounds of your body perfectly, a silky emerald backless piece that shimmered beneath the soft lights of the porch you'd abruptly accoupled. His name might be Lucas – you may have been able to accurately remember that three drinks ago but you're beyond that now. And it didn’t really matter when all you wanted was for him to fuck you. He's also big and huge, massive shoulders caving you in, and his hands is snaking it's way up your thighs, ginger kisses peppered along the span of your neck.

Which is not what you wanted. Not in a one-night stand at least. You don't want soft and gentle, you want something wild – feral even. Something harsh enough to wipe the memory of Jeongguk's hands on your skin, something bright and fierce and new. Something to make you feel alive again.

Lucas gets the hint soon enough, spurred on by the bold movement of your hand guiding his closer, right between your thighs were you wanted him. Deft harsh fingers on your clit followed, pressing against the damp fabric with no remorse. You couldn't help the whimper that floats from your lips, the tension stringing through your limbs finally alleviated.

"Cute," he murmurs, seemly pleased judging from the broad smile that tugs at his lips. You make a noise of agreement in return, drawing in him for a kiss as the pad of this thumb toys with you. There's the sillage of whiskey on his tongue, something that nearly makes you freeze because you're used to tasting that on Jeongguk. But you beat down that apprehension, a muffled moan breaking past your lips when Luca's tongue mets yours.

"My place?" He suggests, lips glimmering from your lip gloss. You smile, a familiar giddiness bubbling in your chest when he shifts a little, hard bulge bumping into the base of your stomach. You give in a little bit more easily than you normally would have, clinging onto his hand as he guides you out of the party towards the neighboring building. Chayoung and Sieun are going to kill you later for this but you simply can't force yourself to care.

"You're in that frat?" You finally murmur out when he keys himself into the building. Lucas hums, glowing under the moonlight when he smiles at you.

"Mhm, Sigma Chi for life, babe."

Babe. A complete one-eighty from the bunny you'd grown accustomed to.

It hits a little harder when he gets you into his room, the mess unlike anything you'd ever seen at Jeongguk's (he's very anal but his room and how clean it should be, specific down even to the various scents he kept around to ensure the air he breathed was perfect). Lucas was the average frat boy, messy but neat enough that you find yourself naked on his bed a couple moments later, his tongue deep inside of you. Your brain couldn't help but recall the last time a head had settled between your thighs, Jeongguk eager to lick out the pool of cum he'd left there. But this wasn't him and as of five seconds ago you decided you’re no longer allowed to think about him.

Lucas makes it easy, tongue skilled and swift around your clit, a fervour in his movements that leaves you dripping down his chin. Jeongguk evaporates from your mind entirely when Lucas descends on you, his mouth glistening and his tongue tasting of you. His kisses are hungry now, forceful, just what you need. Your palms stray down his wide back, a strange tingle erupting in your gut when your nails dig and he groans right down your throat.

"You're so big," the comment is a mumbled slur, lost in Lucas's mouth. For a second, you think he misunderstands, his hard cock twitching against your thigh. You're actually talking about his shoulders; they're broad, muscles rippling every time he shifts to press you harder into the mattress. You like the weight of him on you, it makes forgetting easier.

But Lucas knows what you're saying, discerning your wandering fingers and clouded eyes well.

"I know," he returns with lopsided smile. "Perks of swimming."

Oh, of course he was an athlete. Maybe you had a type after all.

Before Jeongguk has a moment to resurface Lucas has you in his arms, easily twisting you around so that your face is buried in his sheets. It short-circuits you, brain sparking with how large and huge and strong he feels. The following sudden press of his lips against your ass doesn’t help, your heart thumping loud in your head as your shuffle onto your elbows.

"Good?" Lucas asks, rising to fetch a condom from his drawer.

"Mhm," you return, thighs trembling when he returns. He easily lines himself up with you, the head of his cock pressed into you coaxing a low groan from your throat. The first thrust hurts, probably because you're body isn't as on board with this as you thought. But that changes quick when Lucas's hand slides underneath you, swiftly settling on your clit until you're leaking around his length, skin tight with tension and sweat beading along the length of your back. The stretch feels strange – he's larger than Jeongguk, wider. At first it's too uncomfortable to feel good. Your senses narrow on the sound of your meeting instead, loud and lewd, your pussy squelching with every drag of his cock inside of you. The ripple of your ass helps you relax too, a pleasant almost dizzy feel spreading through your body when Lucas draws you closer, shoving himself deep inside, the whine floating from his lips painting your skin warm. He fucks you hard enough to leave marks, large fingers digger into your hips with every resounding collide of your bodies. You shiver when he finishes, a grimness appearing on your skin. It's vanished by Lucas tugging you close, his mouth light on your lip as he kisses you, cock slowly slipping out.

It feels better the second round. He's perceptive, quickly learning how you like your clit touched, or that you like when his teeth sink into your skin rather hard. You actually cum this time, spread open over his massive strong thighs, his length splitting you open, the stretched welcomed.

You forgot about Jeongguk and your sore heart for a total of two wonderous hours, before your phone starts blaring from your discarded mini-bag on the floor. Lucas is the one that gets it for you.

"Hi?"

"Y/N! WHERE THE HELL ARE YOU?" Chayoung's tone is aggrieved, wavering through the sound of some song blasting in the background.

"Oh. I left." You hope she gets it, doesn't press any further. But what was Chayoung if not a button pusher?

"WHERE? YOU WENT HOME? WHEN?"

"No, I'm not home. And awhile ago." Lucas is pointedly not listening, pattering through the adjacent bathroom of his room. The pressure ebbs when he turns the tap on loud.

"WHAT?"

"I said I'm not home! And please stop yelling!"

There's a loaded pause. You can feel Chayoung thinking through the line. "Okay... Who are you with?"

"Fine, yes I'll meet you there," you say instead, completely ignoring her question. Lucas is out of the bathroom now, massive and still naked as his knee sinks into the mattress. He crawls to you as you scramble to get out, phone wedged between your shoulder and ear. "Yeah, yeah I know I'm sorry. I'll come get you."

"What the hell are you talking about Y/N? Who are you with?" Chayoung's words are bitter now, stinging as they hit your ear.

"Gimme five seconds, I'll be right there," you return, swiftly cutting the call. Chayoung is going to kill you the second you see her but you'd rather attempt to live through that than Lucas overhearing you gossip about him on the phone with your friend. The man in question is watching you with a chary gaze as you hurriedly tug your dress over your head. "Sorry," you supply, pulling the hem down hard over your butt. "My friend needs me."

He nods slow, strawberry blond locks swaying. He's actually very hot, an observation that has you stilling for a second.

"Cool. See you around, yeah?" His eyes are round and big, bright even – almost like Jeongguk's. That breaks the spell.

"Yeah, see you around." And then you take the chance to flee, bag swung over your shoulder. Except Lucas halts you with a low cough, raising his hand, something bunched up in it.

"You forget this, though." It's your underwear, red and lacy. Your cheeks match the colour of fabric, flushed hot as you pluck it out of his wide palm. Lucas watches you slip them on with a smug smile, one that you should hate but there's a humour in it that blooms through you. He lets you part with a fond squeeze of ass when he gets up to open the door, still grinning.

"See you, Y/N," he says, leaning against the doorframe. He's very tall too, how did you miss that?

"Yeah," you squeak back, eyes shifting from his face with speed. "See you."

He's not Jeongguk, and that's good. He also makes it easy for you to forget about Jeongguk, another plus. And you can't help but wonder as you scurry back to the party, that it might be nice to see him again.

—

That sentiment gets jumbled when Chayoung avidly spills to you later that she'd stumbled into Jeongguk with his hands tangled with another girls, leading her right out of the party as Lucas had lead you. It stings, of course it does, but not as much as the first one. Not when Lucas is in your DMs, his messages sweet albeit corny, and you can still recall the taste of you on his tongue.

But despite everything, even with Jeongguk a new stranger and Lucas's body warming yours, you haven’t truly let go. You can feel it in how you cling to the clothes Jeongguk had left in your closet. He hadn't requested to come pick them up yet, a fact that keeps a wedge in the door you're not sure you can close alone. Your heart still spikes when you see him on campus, and there's a home game coming around the corner that you're longing to go to. Because you still want to see him. Still want to be by his side Sometimes it felt nice to want to forget but you couldn't – not yet at least, not until you know whether he wants to forget about you too.
