"Is that all you've got?"
Your chemistry professor, Obanai Iguro, spoke, his voice slicing through the air like a blade. Feeling the biting pain of his apathy more than any harsh criticism, you grimaced inside as you heard his remarks. His intense scrutiny pressed down on your already fragile self-assurance, forcing you to look downward.
"I... I'm trying my best, Iguro-sensei." You felt your insides tremble as you spoke with a low voice, which could barely be audible under the quiet hum of the fluorescent light inside his classroom.
You're usually the jolliest and most active student in all science classes, particularly chemistry, because you want to be a chemist. But then, everything changed four years ago when the woman you regarded as an older sister passed away because of her dedication to science and education.
You hated science. You barely make an effort at it right now because it triggers you so much. But, of course, you don't want your professor to know that. Especially because of the rumours about his "allergy to women" and so on. Of course, he wouldn't understand your pain.
With his visage frozen in place, Obanai studied you dispassionately, as if you were a specimen in an exhibit. He repeated, "Your best?" He spoke with an acidic undertone of doubt. "Well, Y/N-san..."
You gulped.
"Your best? It seems severely lacking," Obanai added, his comments cutting through your delicate self-esteem. "Perhaps you should reconsider your actions before I end up failing you this semester. Chemistry's not for the faint of heart."
After saying that, he looked away, shifting his focus elsewhere, leaving you to grapple with the aftermath of his heartless disregard. However, one could not help but detect a hint of warmth and longing concealed beneath the academic dispassion that adorned their facade of indifference.
"I heard another student cried at Shinazugawa-san's classes earlier."
"I know, right! Someone also cried at Tomioka-sensei's. What's wrong with these professors?"
"I don't know. There's another professor, though, who is a terror. That... that weird face mask guy."
"Oh, Iguro-sensei."
"Yes! I'm glad I'm not in his class."
"Yeah, me too. We're lucky that we're in Rengoku-sensei's classes all day. I wouldn't ever complain. He's a ray of sunshine!"
"Uzui-sensei too... He's handsome, too. We're so lucky!"
"DAMN YOU KIDS! YOU'RE SO NOISY! GO BACK TO YOUR CLASSES!"
You watched as Shinazugawa-sensei stepped out of his class to yell at those two talkative students. You gulped, feeling scared that he might yell at you too. But fortunately, he didn't. You can't bear having additional stress today, especially after hearing Obanai's words earlier.
But then, you clearly remembered your earlier encounter. Looking into his enigmatic eyes, you can't help but wonder about that sudden flicker of emotion that he showed you. It's hard to believe, but it seems like there is more than meets the eye when it comes to Obanai. And yes, you're kind of curious to know what that is.
You didn't know that Obanai was secretly watching you on the corner. He's used to hearing students complain about him, so it's surprising that you didn't escalate the situation after hearing them. Especially considering what he did earlier.
"Am I too harsh again, Kaburamaru?" He asked the harmless snake, who was just busy slithering on his shoulders. No answer came, of course, so then Obanai just went back to his lonely classroom.
In the days that passed, Obanai's harsh words still haven't left your mind. But yes, even if you wanted to do your best, his subject is just so hard to deal with, not because you find it hard, but because of the sad memories that it brings you.
As you sit and listen to him in his classes, you can't help but find yourself grappling with a tumult of emotions. So one afternoon, you were astounded to feel a presence beside you, only to discover it was the chemistry professor. You were startled to see his heterochromatic eyes fixate on you with an intensity that took your breath away.
"Y/N-san," he said, his voice more muted than you'd ever heard before, but with an understated strength in its tone. "May I have a word with you?"
Your heartbeats were quickening at the unexpected invitation. "Of course, Iguro-sensei," you replied, your voice tinged with a mixture of apprehension and curiosity.
Obanai led you to a secluded corner of the hallway, away from prying eyes and wandering ears of the other college students. As you both stood there, bathed in the soft glow of afternoon light, you couldn't help but notice the subtle shift in Obanai's demeanourโa concern that belied his usual stoic composure.
"I've been watching you, Y/N." Your chemistry professor began with his heterochromatic eyes, meeting yours with unwavering curiosity. "You seem to be more lost than when I first talked to you. Is there anything you need to tell me?"
"As far as I know, there's none, sensei."
Obanai raised one eyebrow at you and crossed his arms, only to reveal Kaburamaru, who was hiding beneath his oversized lab coat. You blink in confusion at what you are seeing right now. You have heard the students talk about Iguro bringing his pet snake to the university a lot of times. However, you regarded those as purely rumours.
But seeing the white snake right now, you can't help but be amazed. You also had a pet snake in the past, which you and your best friend used to take care of. "Oh, what's its name?"
"Kaburamaru."
"I see. It looks beautiful..."
"Oh? You're not afraid of him?"
"No. I'm not. He reminds me of the snake that I used to see on our garden before."
"Oh..."
"Yes, sensei. Hmmm, when I was just 5, I used to see a white snake in our garden. I even tried to touch it."
The oozing tension and unwelcoming aura that Obanai used to blanket himself with seemed to fade as his eyes widened with what you said. He looked amused right now, and that kind of calmed you down.ย
"I see..."
It looks like he wanted to ask more, but then nothing came. So, you decided to get straight to the point.
"Iguro-sensei, I've got to go. I'm so sorry if I always disappoint you in class. I really do."
You said you felt guilty for letting your emotions always take hold of you. But before you could go, Iguro handed you something.
"A notebook?"
"Yeah. Try to study with those notes. Perhaps it could help."
You took the white notebook from his hand and gave him a small smile. "Thank you, sensei."
You swear that before Obanai turned around, you saw his cheek turn pink. That left you dazed, but then, it's none of your business.
Despite the amusement that you have felt for knowing Obanai has a soft spot, you can't help but not believe yourself for what happened. Why did he give you this notebook? Why is he observing you in the first place?
It kind of made you shiver, as you felt like one wrong move and bad things would happen with Obanai. Interpreting that moment as a sign of his concern for you, you chose to give him the benefit of the doubt. Perhaps...
After showering, you sat on your study table and looked at the innocuous photo in front of you. It was your best friend and non-blood-related older sister, Shinobu Kocho, who had passed away. How you've missed her and the time when she's just there for you. You loved the girl so much that you wanted to be like her.
You never would have thought that one day you'd end up hating something you love for taking someone away from you.
"Shinobu-san, I'm sorry for being a failure. I... I'll try my best to bring back my passion."
You whispered in the air, realising that, yes, if the woman is still here, she wouldn't want you to fail.
With that sudden flame igniting inside you, you opened the notebook Obanai had given you. Goosebumps formed on your body as you traced his handwriting. He has good handwriting, and you can't help but smile because of it.
It reminded you of Shinobu's wonderful handwriting, which you have always adored but also sort of didn't, as Obanai wrote in cursive.
And with that, as if by magic, time passed. You didn't realise that it was actually two in the morning when you finally stopped reviewing. Yes. It has been the first time again that you have let yourself get too absorbed in anything related to science for more than an hour.
It kind of felt overwhelming. Yes, it is overwhelming, as suddenly everything started to make sense again. All the things that you studied before came back. And perhaps it is due to the simplicity with which Obanai explained things in that notebook.
It seemed as though he had specifically designed it for that purpose. To make chemistry simple, which is too different from how he explains things in class.
For some reason, you felt a bit happy. Even if Obanai may appear nonchalant and harsh, he seems to really care. This simple gesture unlocked so many memories.
And even your promise to Shinobu before came back to you, pushing you harder to do better this time.
This is all because Obanai has made an effort to kind of talk to you at the uni this afternoon. And yes, he is cold but that gesture had gave warmth to your frozen heart.
A few days had passed, and one Saturday night, you found yourself sitting in a public library, reading the notes from Obanai's notebook. After the night of your realisation, you felt your passion for science spark again. And yes, it reflected on your grades.
However, Iguro still didn't speak to you after that day. No praise, not even a bat of an eye. You're just there again, invisible, despite doing your best.
Feeling a bit low, you decided to ditch the library and head towards the nearest coffee shop. All you wanted now was to chill and perhaps let your mind rest for a while.
But before you could reach the coffee shop, you accidentally bumped into someone. Without wasting time, you bowed down to apologise, and there, a familiar voice came into your senses.
Your eyes widened, and then, when you looked up, you met those familiar and enigmatic eyes. "S-sensei?" you asked, wondering why in the world would fate bring him to you tonight.
You were trying your best to forget him and his nonchalant attitude towards you, which is really weird after he gave you that notebook. Yes, you were expecting him to be a bit nicer, but he became colder.
"What are you doing here?"
He's still wearing his mask. I wish I could just see his face.ย You thought as you proceeded to take in his presence. Clad in a striped hoodie and black pants, Obanai could pass off as a university student. He looks young for a professor in the first place.
"Hey, I'm talking to you."
"Oh sensei. Sorry, I wasโ"
"Spacing out. I know. It's okay. I know it's surprising to see your professor around here."
You were astounded when he talked casually to you. He never did that at school. Oh well, that's because he's apparently your professor. You wanted to slap yourself for your foolish thoughts.
"What's up with you?" Obanai added, which made you blink in surprise.ย He wants to know what's up with me.
"Nothing much sensei... Justโ"
"I'm going to cut you there." He said, and suddenly leaned in on you, which made you blush. His voice went out as a whisper as he told you,
"We're outside the university. It's Obanai, okay? I don't want the people around getting the wrong idea."
"Sorry senโ Obanai-san..."
He straightened up and crossed his arms, piercing you with his fierce eyes once again. "So you were saying?"
"Oh, I was just reviewing. Just heading to the coffee shop now to grab a coffee. How about you?" You said, trying to hide your nervousness from your casual tone. Obanai scratched his chin and shrugged his shoulders.
"Nothing much. Just another Saturday night in the pub, I guess."
WHAT? HE DRINKS?ย You couldn't hide the flabbergasted expression on your face as you heard those words coming from his mouth. You never thought of Iguro as some guy you'd see in pubs. So this information is shocking to you.
Obanai saw this expression and raised an eyebrow. "Is it weird to hear a grown ass man going to a pub? Why are you looking at me like that? Prick..."
"Sorry... I'm just... weird sometimes. Don't mind me."
"Okay. So, you heading towards the coffee shop? Want me to come with you? It's quite dangerous to walk alone in these streets at night."
This night is definitely getting weirder... in a nice way?
Obanai, asking to walk with you? The stern and cold-hearted chemistry professor, caring for you? You bit your lip and felt a bit flustered.
Yes, he's your professor, but he's also a guy. And it's the first time that a guy has ever offered you this. You know that it isn't too much. It's most likely lower than the bare minimum, but then a part of you started to flutter. You know it's wrong, and it's weird... but... For some reason, you just didn't care.
"Are you sure I'm not going to be a bother with you and your pub appointment?"
"No. I'm kind of thinking to drop the pub thing tonight, actually. Can I join your coffee appointment instead?"
"Why?"
"I don't know. I just want to? Is that an enough reason?"
"Yes, actually."
You found yourself sitting face-to-face with Obanai in your favourite coffee shop, wondering why he was here in the first place if he wouldn't order at all. Feeling a bit conscious, you fixed your braids and decided to take a sip of your coffee.
"Why didn't you order anything? If you want to go to the pub, it's okay."
"I just... don't eat much. And I hate coffee."
"Then why did you go with me here, sensei?"
"Obanai."
"There's no one around. And you're my sensei; we can't hide that fact."
"You're pissing me off."
"I'm not trying too, though. It's just..."
"Why did you stop? It's just what?"
Obanai's voice suddenly sounded a bit offended and sad. You gulped and looked down, stopping yourself from saying that this looks weird because somehow you wanted the company.
"Nothing"
"You can tell me directly if you don't want the company. I just came here to... to make sure you'll be alright. But I guess trying to be nice doesn't always pay off?"
You felt guilty as you watched Obanai stand up from his seat. So then, letting your intrusive thoughts win, you grabbed his hand and pulled him down. "Stay." You didn't care if his allergy to women would be triggered by this contact. All you wanted to do now was kind of comfort him.
Obanai looked at your hand and back to you with question marks almost becoming visible on his face. "Y/N..."
"Sorry..."
"It's okay. I'm used to it."
"I want the company. So stay, Obanai."
The facade of emptiness in Obanai's eyes was shattered after hearing your words. It seems like a memory has suddenly been unlocked inside of him. But then, no words came out of his lips. So you spoke up once again, trying to lighten up the mood.
"So... where are you going after this?" You asked innocently, which made the guy shrug his shoulders again. Obanai isn't speaking again.
You realised that he was looking at your hand, which was still holding him, so you pulled away and tried your best to hide your blush.
After you had let go of his hand, Obanai finally got the strength to speak up. "Walk you home."
"You're not pissed off with me anymore?"
"No."
"Okay."
"Okay."
And there... Again, you found yourself ending the night with Obanai walking you home in silence. Yes, it was awkward, but for some reason, it felt a bit warm. And you kind of felt happy.
Yes, he's your professor, but for this night, he made you feel like a normal girl. And yes, it is special, as you haven't felt that in a long while.
Actually... you have been feeling this for a while. Wanting his attention and care so bad and you didn't know when it started. It just sparked again after he lent you the notebook.
But you know you shouldn't feel this so, you forced yourself to stop. And you'll do it again this time.
On the other hand, Obanai found himself slithering back to the pub, letting his loneliness get a hold of him. Yes. He's lonely. And yes, he regretted what he just did. Just because you reminded him of something so important before doesn't mean that he should be as vulnerable as at that time.
You're his student. And yes, he reminded himself of that. You're just his student now. And it should stay that way.
Days have passed, and here we go again. As if that night never happened, Iguro didn't talk to you that way again. It kind of hurts because even if you wanted to hide your feelings so bad, you still wanted him to look at you and speak to you, the same way as that night.
But you have no choice. Even if you had the urge to bring up how confused you are, you didn't. You can't speak to him that way again. Like what you said that night, he is your professor and you cannot hide that fact.
So, you just did your best in his class, trying your best to focus on your promise with Shinobu, trying to fix all your mess.
Little did you know, but the chemistry professor has noticed how you've changed since the day he lent you those notes. You've turned the tables, as if suddenly you were his star student.
He had grown fond of seeing you answer his questions correctly. Especially when you started leading chemistry projects and stuff.
And beneath those observations, Obanai can't help but also adore how beautiful your confidence looks on you. Yes, he was dying to talk to you. But he can't bring himself to do so. He just can't say it but there's tonnes of things that he had been wanting to tell you.
"Iguro-sensei. Thank you for this notebook. I've finished studying them all, and it helped me a lot. I will return it to you now. Sorry if it took me too long to do so."
Obanai was astounded by your voice and presence. He looked up at you with an empty stare and simply nodded. After putting the notebook on the desk, you were about to go when, suddenly, Iguro spoke up in a soft tone.
"No worries. You actually started to do well."
With his words, your face lightened. Feeling your heartbeat race, you fought the urge to smile as you knew that things would not end with him praising you. You still need to pass the class. You need to make Shinobu proud, even if she's gone.
But then, cutting off those thoughts, Obanai stood up from his seat and walked in front of you. You were astounded by the sudden closeness, but of course, you didn't move.
The chemistry professor's heterochromatic eyes pierced within your soul, forcing you to look away. Heat crept up on your face, and you felt that the atmosphere had become a bit more intense.
A sudden, foolish thought had managed to escape from the cages of your mind.
Is Iguro-sensei going to kiss me?
Yes. Rising again from deep within your frustrations on his subject and the pain that it causes you is this feeling. And it is slowly burning you into ashes.
That's why it hurts more when he tells you you're not good enough. That's why you didn't get angry at him when he did so. That's why you hated those people who spoke badly of him.
That's why you wanted his attention again like that night when he made you feel like a normal girl.
Yes, Iguro can be so difficult, but he somehow brings this comfort to you. You have no idea why, but it's like you've known him forever, and you've been longing for his presence.
He feels familiar, but he also does not.
Obanai's hand felt warm on your cheek. The chemistry professor suddenly found the courage to caress your cheek, which made you blush. But then, his next words killed those flusters in just a blink of an eye, rubbing salt on your scars.
"You did well, Y/N-san. Keep it up, okay? You'll make Shinobu proud."
Those words. That name.
You almost found yourself shutting down. Now, all you can think of is: How did he know her? And if he has known her for a long time, why is he just telling you this now?
Turning to look at him with wide eyes, you've witnessed how Obanai took off his face mask. Yes, this is the first time you've seen him without that.
And yes, for the very first time, he looked so familiar that seeing his face now brought back your old memories from the foster home to haunt you.
Flashback:
"Shinobu-san, who's that boy with Mitsuri-san? Is he new here?"ย
"Oh, I don't know his name but yes, he's new. Don't approach him, though. He seems to be afraid of girls. I don't know why, though."
"Afraid? That's weird. He seems to be okay with Mitsuri."
"I know, right. Enough questions. Let's just study inside. Ne-chan told me that you'll be a Kocho soon! So you'll need to learn lots about science!"
"Hey. That snake will bite if you hold it that way."
"Oh! Sorryโ Um, you're Mitsuri-san's friend, right? You're not afraid of me?"
"Oh..."
"Oh..."
"Anyway, don't hold it like that. Aren't you afraid of it?"
"No..."
"Hey! Why are you playing with a snake?!"
"Oi Shinobu-san! Mitsuri's friend wasโOh, where is he?"
"Huh? That boy? He's not supposed to be here... Perhaps he ran away. I heard he had been adopted. But you know what? Let's just go inside. Leave that snake alone."
"Shinobu-san! I know that guy..."
"Yep. He's that kid from before. He's all grown up too. I guess, we'll be co-workers now? He'll be volunteering here as well to teach science with me. Anyways, Mitsuri's also here, she'll be teaching art. You should meet with her soon!"
End of Flashback
"Iguro-san? Y-you look... familiar..."
"Yes. You've met me and Kaburamaru before."
"You are kidding right? You can't be that boy from the foster home. Mitsuri-san's friend? My sister's co-worker? You died... You're already dead... Like them..."
It seems like your words have stunned Iguro. Regret started to paint on his face as he looked away from your wondering expression.
But here you are now. Answers. You need answers. If he had known you all this time, he must have known the trauma that you experienced when you saw the foster home getting burned with Shinobu, Mitsuri, and that unknown lad, who is apparently him, as they tried to save the children that they had been teaching science four years ago.
Why is he here now?
You shove Obanai away and glared at him. "This must have been a sick joke, sensei. You can't be that boy with my sister... No one has escaped that fire that night."
"I did, and I'm sorry I wasn't able to save your sister and Mitsuri."
"It's all too much for me now. Can I go?"
Tears suddenly escaped your wide eyes, and there, Obanai felt his chest tighten. He had expected you to react this way, but no matter how he practiced it, he could never prepare himself for the real thing.
Just like how he wasn't prepared to see his first love get burned to ashes before.
"Y/N, I'm sorry." Obanai tried to touch you, but then you swatted his hand away and gave him a glare.
Your passion turned to anger as you felt betrayed. All you can think of is why. He should have been honest. What other things is he hiding from you, then?
"Y/N, I never knew at first that you were Shinobu's sister. I heard she has siblings, but I didn't even know who they were. I and your sister barely had any encounters before except when we were teaching the kids at the foster home. How could I know?"
You didn't speak. You wanted to hear more.
"I mean, it just dawned on me when you told me about your memory back when you were 5. That's the only time I managed to fit in the pieces."
"What do you mean?"
"You're that little girl I saw when I was 12. The girl whom Kaburamaru almost bit. You had Shinobu's surname, so you got adopted by them. So that's also why you were gone when I came back to visit. Y/N... You were here with me all the time. It was all late when I realised it."
"Then why didn't you say anything?"
Obanai's eyebrows creased in frustration. "What should I say then? 'Hi, I'm Obanai, the boy from the foster home who also didn't manage to save your sister from the fire. How are you?'"
Sarcasm was obvious in his tone, which offended you a bit, so you decided to just leave. Perhaps this conversation shouldn't be happening right now. You want to move on. You're moving on, for goodness sake!
And now you're back to square one again.
