[Hogwarts!AU] Kwon Soonyoung might be too curious for his own good. He enlists the help of an equally enthusiastic and curious Ravenclaw to solve the mystery of the several odd disappearances of one Kim Mingyu.

! as part of the #svtbiasswap challenge, this work is dedicated to my new friend and fellow ravenclaw, @nikosomething 🐯💕

“I’m telling you, it’s a real mystery!” Soonyoung attempted to convince Wonwoo and Jihoon for what must have been the fiftieth time. He was growing more determined as the middle of the semester drew closer. Winter break was just around the corner and he was getting nowhere close to solving the mystery of the odd disappearances of Kim Mingyu. “I really need your help!”

Soonyoung’s words seemed to be going in one of Jihoon’s ears and out the other as he attempted to write his Potions’ essay. Honestly, at this point, Jihoon could not be bothered in the least. He’d be damned if he let an overly enthusiastic Slytherin ruin his status as Snape’s favourite Ravenclaw. “You said something similar about a three-headed dog in our second year too.”

“Oh, I remember that one!” Junhui the Hufflepuff quipped from his spot on the windowsill, pointing his wand a bit too close to Jihoon’s nose for the Ravenclaw’s liking. “Didn’t someone almost die? ...Do I remember wrong?”

“There was no three-headed dog in the forbidden hallway,” Jihoon insisted, sparing Junhui a rare glance. “It was just a rumour, for crying out loud!” He pointed his quill at Soonyoung and Junhui in turns. “You two need to stop believing in conspiracy theories! Start studying instead! It’s our final year. No more joking around.”

And just like that, he was back to writing his essay, leaving his friends once again to the knowledge that they were just below his N.E.W.T. score in Jihoon’s priority list. A bummer, really.

“But I’m serious!” Soonyoung whined still after a short pause and fell to his knees. “Please help me! I need to find out what’s happening!”

Jihoon finally relented with a sigh, looking up from his essay and raising an eyebrow. “Why?”

“... For fortune and glory?”

Soonyoung’s cutest and toothiest smile quickly changed to a pout when Jihoon scoffed and turned back to his essay. Unsurprisingly, Wonwoo wasn’t giving him even that much attention, far too focused on the most recent issue of ‘Quidditch Monthly’.

“Oh, come on,” Soonyoung complained once again, plopping down in the seat next to Junhui. He turned to the last of the three, his last true friend: “You’ll help me, right? You won’t betray me like this?”

To his dismay, the Chinese student grimaced and shook his head faster than one could say ‘butterscotch’. “Sorry, I’ve got homework.”

Soonyoung huffed, defeated once again. “Right. Since all of you are so studious. I must have forgotten.” He shook his head disappointedly as he crossed his arms over his chest. “I’ll have to do this one my own then.”

“I’ll file a missing person’s report if you disappear,” promised Wonwoo.

With a small nod, Soonyoung agreed, “Right. I’ll probably go missing before the semester ends, since this is such a dangerous quest. Who knows, they might be doing something illegal!”

“I sure hope so.” Jihoon didn’t even bother to keep his voice low, earning both chuckles and a glare from the people around him. Upon hearing Soonyoung’s defeated sigh, he finally sat up straight and spoke, “You know, I know another Ravenclaw that might be able to help you. You could ask them to join you.”

“Not to be rude, but Soonyoung’s not the type to get along with Ravenclaws,” Wonwoo snickered, finally looking up from his magazine. “This is a terrible idea.”

“Hey! I get along with Ravenclaws just fine!” Soonyoung pouted once again. “I’m friends with you two, aren’t I?”

As silence ensued for just too long for it to be a coincidence, Junhui smiled sympathetically. He reached over to pat Soonyoung’s shoulder. “It’s okay to cry.”

Shocked to his core, Soonyoung straightened in his seat. Accusingly, he pointed at the two Ravenclaws in front of him. “Wait, you guys don’t think we’re friends??”

Jihoon’s eyes widened comically. Neither Soonyoung nor Junhui nor even Wonwoo had ever seen the boy this panicked before. Shoving his parchment and quill to the side, he jumped up and slammed his hands on the table before sputtering: “It’s not that! We’re friends! Who said we’re not friends?! We’re great friends! Right, Wonwoo? Right. We’re the best of friends. Yes.”

He finally sat down after a deep breath, eyes still wide like he’d couldn’t believe what he was doing and seeing as he slumped in his chair (Soonyoung assumed he was having an out-of-body experience). Even Madam Pince’s disapproving shushing couldn’t snap Jihoon out of it.

“To be fair, Jihoon’s friends with like half of Hogwarts and a third of Hogsmeade,” Wonwoo pointed out after a short pause. He smiled at Soonyoung. “But I’m still your friend, really.”

“... Then WHY won’t you help me?”

“Because it’s a dumb idea.”

Soonyoung sighed in defeat. This was the final blow. He melted into his seat and considered himself officially one with the chair. “Fine. What’s their name? Where do I find them?”

He found you right where Jihoon and Wonwoo had said you would be: in the library, hidden between the shelves of muggle literature, a fantasy novel in your hand. He almost scoffed at how easy it was to find you, his eyes landing on you almost as soon as he walked into the muggle section of the library.

After taking a deep breath and double-checking his appearance through the hand-held mirror Junhui had kindly lent him, Soonyoung finally approached you after felt like forever of just watching.

He couldn’t help but shiver in anxiety. Perhaps Wonwoo was right and he just had no business making friends with Ravenclaws. Maybe you were just like Jihoon and would flat-out deny his request. Or maybe you were a Ravenclaw closer to Wonwoo, ignoring him in favour of the reading in your hand. The possibilities were endless and it was upsetting.

To his surprise, you acknowledged him first. “Oh, Soonyoung? What are you doing here? I didn’t know you liked muggle literature.”

“I… don’t…” It took more effort than usual just trying to form words. Was it getting hotter in the library? Where was all the oxygen?

His tongue felt heavy and dry in his mouth as he attempted to find a way to coax you into helping him. “Jihoon said that I— That you— That we—”

Now, maybe you weren’t the brightest among Ravenclaws. Maybe you weren’t particularly good with men. But even you could see he was uncharacteristically nervous about something.

Your mind flashed with an idea that made you shudder. You sat up straight and prepared to pull out your wand, already recalling the most reliable hexes in your mind. “I swear, if you’re going to try and flirt with me, I will—”

“NO! Oh god, no! Absolutely not!” Soonyoung held his hands up in the air as he stared at you like you’d lost your marbles. “Please, I am not that type of guy!”

You had some doubts about this claim, but decided to give him the benefit of a doubt. You were nothing if not a kind soul just trying to get through school. “Then what do you need? And what does Jihoon have to do with it?”

“Okay, so,” he took a deep breath between hand gestures as if trying to gather the energy to blow up at you as he sat down right in front of you, “do you know Kim Mingyu?”

“... The tall guy who hangs out with Minghao? I know him. He seems nice.”

“Wait, you know Minghao?”

You raised an eyebrow. “He’s in my partner in Potions. And a Ravenclaw.”

“Oh.” Soonyoung looked deflated. “I guess that makes sense.” Within seconds, he was back to his previous energy levels. “He’s been going missing every Saturday for the past four years. Four. Years!”

“Okay, and?” You almost gave up on this boy, unable to see what he was getting at. But then an idea struck as you glanced at your watch. “Wait! Does he disappear around 9 in the morning?”

As he leaned forward, Soonyoung’s eyes widened. “How did you know? Have you noticed too?”

“Well… kind of?” You recalled a hazy memory of Mingyu with Minghao, strolling through the castle a bit after 8 on a Saturday. “Minghao always disappears around that time on Saturdays.”

“No way. Do they go together?” If the look in his eyes was anything to go by, he was preparing a conspiracy board in his mind, red strings and everything. “Now that I think about it, Jeonghan and Joshua also used to disappear around that time… This is bigger than I thought.”

“I saw Joshua in the castle just a few days ago,” you recalled mostly just to keep the conversation going. You didn’t think it was a big deal. Or, maybe that’s what you told yourself to keep from bursting with excitement at the notion of a new adventure. “He was hiding behind a plant, I think.”

Soonyoung’s lips formed a tense straight line. “He’s not very good at hiding…” He sat up once again, audibly cracking his back from the speed of his movement. He groaned at the slight pain before continuing on. “Wait, Joshua? In Hogwarts? Didn’t he graduate last year?”

"Whatever they do on Saturdays, it must be pretty big,” you concluded after a moment of thought. “Minghao’s very secretive about it too…”

“So, Mingyu, Minghao, Jeonghan and Joshua? Together?” Soonyoung hissed through his teeth.

“Is it— It can’t be illegal, can it?”

Soonyoung smiled at you. “That’s why we need to solve this mystery and find out.”

“I’ll ask around the Ravenclaw house, see what I can find. You see if Slytherins know anything.”

“You can’t be serious,” Jihoon groaned as you told him about your day in the common room.

It was well past midnight; he, you, and Wonwoo were the last Ravenclaws remaining in the cozy light of the fireplace. Just the right type of atmosphere to relay the news to your dear friend and mentor, Lee Jihoon.

He ran a hand over his face rather roughly, as if to rid himself of any expression. Eventually, he peeled his eyes open and gave you a rather hopeless look. “Please tell me you’re kidding.”

Unimpressed, you raised an eyebrow. “You’re the one that gave him my name and hiding place.”

“I gave your name to him kind of like a joke! I didn’t think you’d actually help him! Or that he’d even ask!” He threw his hands up in frustration. “He’s only gonna get more insufferable now! I could barely keep up with the conspiracy theories before…” He let out a toddler-like cry.

“Aren’t you happy your two friends are now friends?!”

Jihoon looked to Wonwoo for help. The latter didn’t blink an eye as he dipped his quill in more ink and continued his homework: this was none of his business, but the detention he’d receive from McGonagall surely would be. After all, you were Jihoon’s responsibility and had been since your first month at Hogwarts, as per the prefects’ request.

Eventually, Jihoon gave in to your unwavering stare. “Of course I’m glad you guys are friends now. I’m happy you’ve found each other. It’s just…” He sighed. “He’s Soonyoung and you’re you and I could barely handle you two when didn’t know each other.”

“Come to think of it, you and Soonyoung are kind of similar…” Wonwoo mumbled just loud enough to be heard and prompted Jihoon to let out another helpless cry that sounded more theatrical than anything.

“You know, you could’ve just volunteered yourself to help Soonyoung,” you reminded him, stretching out on the sofa. “Then you wouldn’t have to worry about me hanging out with him and could spend all time with him yourself.”

The look in Jihoon’s eyes cleared up. You felt horror climb up your spine as he slowly sat up and began smiling. “Actually, now that I think about it, that’s great! You’re perfect! This is perfect! You deal with his conspiracy theories!”

“Wait, what? That was— What?!” You sat up to stare at him.

He looked like he’d just won a 10-day all-paid-for vacation in Hawai’i, a bright smile on his face. “This is great. I’m so happy.” He reached over to pat your shoulder in mock sympathy. “He’s your responsibility now.”

“Jihoon—”

He shook his head rapidly. “No, no, you’re helping him. I want nothing to do with this.”

“... I’ll set the conspiracy board up in your room at this rate.”

He snorted. “Joke’s on you, girls can’t visit the boys’ dormitory.”

“Joke’s on you, your roommate owes me a favour.”

“... Damn it.”

You stuck out your tongue, he soon reply with a similar gesture. Was it immature? Perhaps. But there was no one there to judge.

“You know,” Wonwoo started slowly, eyes still locked onto his Transfiguration homework, “I could have sworn I saw Mingyu and Hao in Hogsmeade last weekend.”

“Hogsmeade?” You hummed in thought. “That’s possible. But didn’t Minghao get in trouble in 3rd year because he didn’t have a permission slip?”

Jihoon pursed his lips in thought. “Maybe he got one later? In 4th year?”

“You know what? I’ll take this up with Soonyoung tomorrow.”

“You’re meeting tomorrow?!”

“When else?”

Your mentor and friend dearest let out a loud wail once again.

“Interesting,” Soonyoung mused as you relayed the information to him. “I’ve never once seen Mingyu in Hogsmeade. Never.”

You shrugged. “Well, I don’t think Wonwoo would lie. He’s not that type of guy.”

“True. He’s too honest for his own good.” Soonyoung leaned back in his seat, a thoughtful look on his face. You just watched him for a while as he mulled over the plan of action.

After a few minutes, he sat up once again. “Do you have plans on Saturday?”

“Plans?” You blinked at him in surprise. “I don’t think so? I usually just go to Hogsmeade with Seokmin after tutoring him.” Your eyes narrowed. “What are you planning?”

“Let’s follow Minghao and Mingyu,” he suggested way too enthusiastically. “Then we’ll know where they go all the time!”

A smile made way onto your lips. “Like a stakeout from those detective movies?”

“Detective movies? That’s a thing?” Of course poor pureblood Kwon Soonyoung had no idea what detective movies were. You felt fondness grow in your heart. “Anyways! Let’s see where they go.”

“You got it, partner!”

“Oh…” He giggled. “I like that. Partner.” A bright smile appeared. “Let’s do this, partner!”

Soonyoung could barely keep his eyes open as you led him through the halls of Hogwarts. Even worse, he could barely compile meaningful sentences. You began to wonder if maybe this was a bad idea.

“Why are we out of bed at 8 am?” he whined, his voice hoarse from the 12 hours of sleep he’d been so rudely awoken from. “They don’t disappear until around 9…”

“We should just following them sooner than then. Otherwise, they’ll disappear before we can find them.” You pulled him to hide behind wooden barrels sitting on the opposite side of the corridor, where you had a clear view of what you’d been told was the Slytherin dormitory entrance.

Your partner-in-crime (-in-justice?) hummed in thought, eyes threatening to close. He eventually agreed with a slightly less doubtful hum.

“Oh!” He suddenly awoke, eyes much rounder than they’d been before. Frantically, he slapped your arm and pointed towards just the guy you were looking for: Kim Mingyu sneaking out of the Slytherin common room, dressed in black sweats from head to toe, a dark jacket under his arm.

He glanced around doubtfully, surveying the area and somehow missing you and Soonyoung hiding behind barrels. Once he decided he was in the clear, he breathed in relief and began rushing up the stairs,all the while shrugging on his jacket.

“Let’s go,” you ushered your partner to follow the taller student. “He’s gonna get away.”

“I’m coming, I’m coming,” Soonyoung whispered, sticking close to you as you made your way.

When you finally got up the stairs, you were met with a rather unpleasant view. It was just plain nothingness.

“He got away.” Soonyoung pouted. “We were so close.”

“How did he get away?” you wondered, looking around as if to find a footprint or a map somewhere on the ground or on the walls.

Map... A brilliant idea came to your mind but you brushed it off for the time being —you’d have to ask Wonwoo about it later.

“He was just right in front of us.”

“Let’s just pick a direction and go?” Soonyoung offered rather helplessly. “Maybe we’ll get lucky?”

You sighed in defeat. “Wherever he went, he’s a long way ahead of us now. There’s no way we’ll catch him today.”

Soonyoung sighed harshly. “Let’s try again next week, I guess.” You now realized he gave up rather easily. This did not amuse you in the least.

“No,” you decided, almost glaring at him, “we are going to Hogsmeade and seeing if Wonwoo’s claims have any truth behind them. Maybe we’ll find Mingyu in Hogsmeade.”

“I’ve never once seen him in Hogsmeade.”

“Maybe today will be our lucky day, eh?”

He grimaced before mocking you, “Eh?”

“Hey!” You frowned. “I don’t sound like that.”

“You don’t but I am sleepy and frustrated and I desperately want to have breakfast.” He pouted his lips and offered you a mellow look. “Let’s go eat.”

“... Fine.”

“Oh!” He perked up again. You began to wonder if he had mood swings like this very frequently. “We should eat together! Then we can discuss our plan of action!”

He looked so proud of himself, you didn’t have the heart to tell him that’s what you had had in mind anyway. Instead, you followed him to the Great Hall.

To your surprise, annoyance and joy, Jihoon and Wonwoo were already seated at the Ravenclaw table, chatting away about something. You could only assume they were discussing the upcoming quidditch tournament.

“Hey guys!” Soonyoung greeted them loudly enough to have the entire school stare at him. “I missed you!” He ran over to give Jihoon a hug which the latter refused rather aggressively, a grimace on his face.

“Did you bring him here?” Jihoon demanded to know, eyes glaring into yours.

Wonwoo chuckled. “It’s just breakfast, Hoon. Let them be.”

“I just don’t like being touched by this one.”

“Will you die if you give me a hug?” Soonyoung wondered, already seated next to him and grabbing a plate. “Oh, there’s cake!”

You sat down across from him, eyeing apprehensively as he gathered more and more food. As you began filling your own plate, you nudged Wonwoo. “Say… you wouldn’t know anything about a map of Hogwarts?”

“A map of Hogwarts?” Wonwoo took a moment to think. “Depends. What type of map?”

“Just ...a map.”

“What would we do with a map?” You didn’t hesitate to reach over and step on Soonyoung’s toe. His whine was muffled by the amount of rice in his mouth before he began glaring at you without any actual malice.

Wonwoo took a deep breath, hands playing with his spoon as he tried to think of an answer to you. “You could get a map of Hogwarts from that big book.”

“Hogwarts: A History must have at least one map of the building,” Jihoon agreed. “But other than that, I can’t think of any.”

“Hogwarts: A History? That’s an actual book?” Soonyoung couldn’t help but ask. He quickly found himself a target of not one, but three Ravenclaws.

Jihoon snorted. “How did you get to 7th year?”

“Listen,” Soonyoung jumped to his own defence, “I’m not dumb. I just don’t like big books.”

“Who does?” you wondered half-mindedly, more focused on your breakfast.

“Wonwoo does,” Jihoon pointed out with a teasing smile. “I’m sure the book’s somewhere in his room right now.”

Before the boy in question could even begin to argue, you asked, “Are there any other maps? Some that don’t require me to borrow and carry around an entire book?”

Your group of four fell into silence. It lasted a while. A bit too long, perhaps, if Soonyoung’s awkward expression was anything to go by. Just three Ravenclaws and a Slytherin trying to figure out the answer to a simple question.

“I think I might know of one,” Soonyoung eventually spoke up, sounding hesitant if anything. “But, getting it could be kind of difficult.”

“Well, where is it?” Jihoon demanded.

“... In McGonagall’s office.”

The collective groan of three Ravenclaws echoed in the Great Hall.

“There’s no way to get that,” Jihoon concluded tiredly, picking up his spoon and stabbing it into his porridge. “I don’t even know where McGonagall’s office is.”

“Huh. Maybe you could use a map.”

“I swear to god, (Y/n)—”

“Oh.” Seungkwan laughed nervously as the two of you stared at him expectantly. “Oh, I am not doing that.”

“Please?” you begged your favourite Gryffindor, but he wasn’t budging.

“I will not sneak into McGonagall’s office for you two. Never.”

Soonyoung smiled mischievously. “Even if we would give the map to you later?”

“What’s so great about a map?” Seungkwan couldn’t help but ask, lips downturned in distaste. “Just borrow Hogwarts: A History.”

You swore Soonyoung’s jaw creaked as it fell open. “Does everyone know about that book but me?!”

“Yes,” came the unanimous answer.

“But please, help us, Seungkwan,” you tried again, but to no avail.

Soonyoung sighed. “Dude, come on, it’s a magical map.”

“As opposed to most maps in this castle,” Seungkwan mumbled under his breath. You began to wonder how he’d ended in Gryffindor instead of Ravenclaw with a wit like that.

“It shows you where everyone is at the current time,” Soonyoung mentioned. “But I guess if you don’t want more dirt on Chan’s late-night escapades then—”

Seungkwan sighed deeply. “Which part of never do you not understand?”

You watched him for a bit, feeling defeated. This is where your little adventure would end, huh? Shame.

Soonyoung suddenly leaned forward and whispered something into Seungkwan’s ear. The young Gryiffindor’s eyes lit up. “Where did you say this map was again?”

No more than a day later, Seungkwan came to you with a rather inconspicuous piece of folded parchment. He glanced around before placing it on the dinner table. “Is this it?”

“You found it!” Soonyoung cheered, giving him a pat on the back. “Good job, Boo!”

“Why does my surname sound so wrong when you’re the one saying it?” Seungkwan wondered briefly before turning back to the parchment. “So, how does this thing work?”

Soonyoung smirked, looking almost wicked as he pulled out his wand. You watched curiously, feeling almost anxious, as he pointed the wand at the parchment. After a brief pause (one could only assume he was being dramatic), he lowly spoke, “I solemnly swear I am up to no good.”

Gasps sounded from all sides of you as the blank parchment came to life with black ink spreading across it. Jihoon actually squeaked in surprise as the ink spelled out: “Messrs Moony, Wormtail, Padfoot, and Prongs, Purveyors of Aids to Magical Mischief-Makers, are proud to present THE MARAUDER'S MAP”.

“I thought this was just a myth,” Wonwoo whispered out after a brief pause, his eyes wide like those of a kitten staring at a Christmas decoration, “but it’s real. The Marauder’s Map.”

“You knew about this?” Jihoon wondered. “How?”

“My mom used to tell me stories about it. I think this was created by her classmates.”

Soonyoung folded the map open as your group of friends stared at him it in pure amazement.

“See, we’re all here,” he pointed at the Great Hall where your names were muddled together like the messy writings of a first-grader, “and Dumbledore’s in his office… Hagrid’s coming in any second now.”

Your eyes darted towards the large doors that seemed to open on cue, revealing the giant of man. You gasped once again. “It’s real!”

“Wait, you’re gonna use this to chase down Mingyu, aren’t you?” Jihoon eventually realized. He laughed almost maniacally before declaring, “You’re a bloody genius, Soonyoung.”

“Attempt number two, here we come,” you mumbled as you stretched in the Ravenclaw common room at 8 the next Saturday. Soonyoung remained lying down on the bench next to you, just making the most of the last minutes of sleep now that he had travelled all the way to the courtyard from the dungeons. This was the day you would catch Kim Mingyu and Xu Minghao. You were sure of it.

“Attempt number two?” Minghao’s voice caused you to jump in your spot. You pressed a hand to your chest. “What are you doing?”

“What are you doing?” you accused right back and scoffed. “You scared me!”

Minghao laughed. “You’re jumpy today. Why?”

“Just because.”

“Oh, Soonyoung, you’re here too?” Minghao smiled at your partner, waving his hand joyfully. “Are you two friends now?”

You nodded in unison, amusing the Chinese boy further.

“That’s sweet,” he concluded after a moment of just looking at you. “Hey, do either of you want to keep me company today?”

“Why?” Soonyoung wondered after sharing a meaningful look with you.

Minghao shrugged, not a care in his mind. “I’m just bored. Mingyu’s sick and Seokmin has a tutoring date at the library…”

“Oh my god, I forgot about Seokmin!” you squeaked before dashing up to your bedroom. Of course the sweet Hufflepuff was waiting for your weekly tutor session! You’d already bailed on him once!

Soonyoung sighed as he looked at your disappearing form. “I guess there goes the plan today.”

“What plan?” Minghao wondered, tilting his head to the side slightly.

“No plan. What do you want to do?”

You sat across from Soonyoung in the Great Hall and slumped against the table, head falling into the squeaky clean plate in front of you. “We’re doomed.”

“Why?” Soonyoung wondered as he pulled the plate from under your face and began filling it. “What happened?”

“We’ve failed twice, Soon.”

“We won’t fail this weekend.”

You felt a hand gently push your head off the table, forcing you upright. A plate filled with delicious food was slipped in its place, accompanied by Soonyoung’s fond smile. “Eat up. Then we can discuss our plans later.”

“Should we make a conspiracy board?”

“It’s like you can read my mind.”

“Welcome to the official first meeting of the Hogwarts Detective Agency,” Seungkwan announced as he let you into an old classroom. It didn’t look too awful, but you couldn’t resist the urge to throw open all the windows as soon as you walked in. “Is everybody here?”

Wonwoo spoke up, “Jihoon’s not going to come today because he has quidditch practice.”

“Works for me. Okay, so what do we know?” Seungkwan asked after locking the door and grabbing a piece of chalk. He stood in front of the blackboard as you and Soonyoung sat onto the old weary tables. Wonwoo, unlike you, had manners and sat on a chair instead.

You nudged Soonyoung to whisper, “Why is Seungkwan leading the meeting?”

He grimaced before replying in a similar hushed tone, “I promised him he could be the leader of our little mystery club if he got us the map.” Soonyoung shrugged carelessly. “I’m a man of my word.”

“Mingyu and Minghao disappear almost every Saturday between 8 and 9 in the morning,” he then loudly recited as though it was a poem he’d been told to learn by heart for class.

“Almost every Saturday?” Seungkwan raised an eyebrow as he glanced over his shoulder between writing on the blackboard.

You nodded. “They didn’t go anywhere last Saturday because…”

“... Mingyu was sick after a second-year decided to hex him for practice,” Soonyoung finished for you rather unwillingly. He shuddered at the memory of a certain Slytherin boy throwing up slugs in the common room.

“Do I— Do I even want to know?” Seungkwan asked no one in particular before shivering and turning back to the board. “What else?”

“Before they graduated, Yoon Jeonghan and Joshua Hong also frequently disappeared with them,” you added. “Rumour has it, they can be seen around the castle on some Saturdays. Mostly Joshua though.”

Soonyoung’s eyes narrowed in thought, his arms crossing over his chest soon after. “Doesn’t Joshua live in Hogsmeade? I swear he works at the post office.”

“Also!” You sat up, feeling a rush of excitement. “According to the Marauder’s Map, Mingyu and Minghao aren’t in Hogwarts on Saturdays.”

“You checked?” Soonyoung wondered, awe written all over him.

You nodded. “Of course. I had to make sure.”

“So, we can assume Mingyu and Minghao go to Hogsmeade on Saturdays,” Seungkwan wrote onto the blackboard. “But Minghao definitely doesn’t have a permission slip to go there.”

Soonyoung hummed. “Neither does Mingyu. But he doesn’t seem bothered by it.”

“I saw Mingyu at Three Broomsticks just two weeks ago,” Wonwoo spoke up. “But I’m not sure if the guy who was with him was Minghao or someone else.”

“Then… how do Mingyu and Minghao get to Hogsmeade?”

Seungkwan sighed. “We don’t know for sure they go to Hogsmeade. All we have right now is Wonwoo’s confession, but let’s be honest, he doesn’t really see that far.”

“That’s what glasses are for,” Wonwoo replied, adjusting the mentioned offending object on his nose. “I can see just fine. I know it was Mingyu.”

“Let’s go to Hogsmeade together on Saturday and try to find Mingyu and Minghao then,” you suggested. “Then we’ll have actual proof.”

“This is a dumb plan,” Soonyoung grumbled as he counted his galleons. “Also, you have very expensive taste in food.”

“I never asked you to pay for me.”

“I did!” Jihoon cheered. “You owed me anyway!”

Soonyoung sighed. “Do you really think we’ll find them here? It’s quite busy. And we haven’t seen them in Hogsmeade all month.”

“That’s why they’ll come here, if anywhere. Less of a chance of getting recognized,” you guessed between sips of your drink. “Plus, everyone loves butterbeer, and it’s on sale today.”

“Oh, I think I see him! It’s really him!” Jihoon spoke rather quickly, straightening up in order to add a few extra inches to his height. “Someone’s with him.”

“Minghao?”

“I think so? But he seems more…” Jihoon made a questionable gesture with his hands, “... large.”

Soonyoung glanced at the two new customers. A smile soon appeared on his face. “That’s Joshua. I think he’s been working out.”

“You think a lot of things, have you noticed?” Jihoon couldn’t help but joke. “Okay, they’re searching for a table. I should stop staring at them, right?”

You and your partner-in-justice spoke at the same time:

“Yes.”

“Preferably.”

“I don’t think he recognizes me though…” You weren’t sure if your eyes were deceiving you or Lee Jihoon looked genuinely disappointed. “Then again, I guess he can’t see much through those sunglasses.”

A laugh bubbled in your throat. “He’s wearing sunglasses? It’s the middle of November. What even?”

“Just telling you what I see.”

Soonyoung nudged you with a playful smile. “Maybe he thinks he’s a celebrity.” He wiggled his eyebrows.

“Would that make us the paparazzi?” Jihoon wondered before perking up once again. “Oh! That’s Minghao!”

You glanced over your shoulder and indeed: the two were right there, having butterbeers and fried potatoes with no one other than Joshua Hong. “Okay, so now we know they come to Hogsmeade.”

“But neither of them have the permission to do so,” Soonyoung added on, eyes narrowing suspiciously. “So how do they get here?”

There was only one logical conclusion: “There must be a secret passageway somewhere.”

“We need to find it.”

Map in hand, you and Soonyoung wandered the hallways of Hogwarts once again, on an early morning.

“Can’t we do this elsewhere or during another time?” he complained like he always did, sleep still heavy in his eyes and weighting down his eyelids. “This is kind of boring.”

“Aren’t you the one that wanted to solve this mystery?” you asked him, to which he replied with tell-nothing hum, promptly followed by a kitten-like sneeze. “Bless you.”

He hummed once again, head leaning against your shoulder as you led the way in the fading footprints of Kim Mingyu and Xu Minghao. You almost felt bad for forcing him out of bed once again, but guilt was only temporary.

“Huh.” You halted in your place and stared at the map in confusion. The black ink in the form of your classmates’ names had disappeared.

“Wait, where are they?” Soonyoung wondered, glancing at the map with a similar look of confusion. “Weren’t they here just a minute ago?”

You continuing staring at the map. “Could it be… Is that where the hidden passageway is?”

“Isn’t that where that weird statue is?” Soonyoung took you by the wrist and began leading the way. You soon found yourself face to face with a statue of a rather nasty-looking witch. “Is this it?”

You checked the map. “Yeah. This is where their names were last on the parchment.”

Soonyoung stared at the sculpture for a bit, head tilting from side to side periodically like he was weighting the possibilities. You subconsciously began mirroring his movements.

“If this is the secret entrance, how does one enter it?” he eventually questioned, beginning to walk around the statue. He knocked on the witch but seemed to gain nothing but a bruised knuckle from the action. He hissed in pain, rubbing the spot pitifully before pouting at you. “What do we do now?”

“Now, we wait.”

Soonyoung blinked, looking almost disappointed in you. “... Are you suggesting we just stand here all day and wait for them to return?”

“Do you have a better idea?”

“... No…”

When you woke up a while later, your back sore and Soonyoung practically drooling your shoulder, you finally admitted to yourself: it was kind of a horrible idea.

“When did we fall asleep?” Soonyoung mumbled from next to you, eyes barely opening. His lips pursed into a pout as he lifted a hand to rub his scalp. “My head kind of hurts.”

“Me too,” you sighed and opened the map. To your surprise, the map showed the names of Mingyu and Minghao right where you were sat. You looked around but saw no one.

Then, a sound of stone dragging on stone echoed in the corridor. You shared a look with Soonyoung who was already up on his feet and dragging you over to the other side of the statue.

You watched in astonishment as the hump of the witch opened, revealing the smiling face of one Kim Mingyu. He glanced around briefly before hopping out of the statue. Minghao followed quickly after, the hump closing behind them.

Soonyoung couldn’t hold back on his excitement and jumped in front of them. “Halt! I know your secret!”

“Soonyoung?” Minghao tilted his head to the side. “What are you doing here?”

“Solving a mystery.” He smiled widely. “I knew it! I knew you were being suspicious!”

Mingyu scratched the back of his head. “We just went to Hogsmeade.”

“Through a secret passage?” you interrogated, knocking on the witch’s back. “How did you even know about this?”

Mingyu smiled proudly. “Jeonghan told me about it. It’s pretty neat, right?”

“... And you weren’t doing anything illegal or weird, right?” Soonyoung questioned with narrowed eyes and a wand pointed at the taller boy.

“No!” Mingyu whined, stomping his feet a little as if to prove a point. “We just wanted some fresh air away from Hogwarts every once in a while.”

“What was with the disguises though?”

Minghao smiled sheepishly. “We got caught by Snape once and almost got suspended because we don’t have permission.”

Lowering his wand, Soonyoung sighed. “And here I thought it was an exciting mystery.”

“No, but it was! It was fun!” you assured him with a pat on the back.

“Can we… Can we go now?” Mingyu asked, pointing away from you. “We kind of don’t want to get caught by Filch.”

“Wait, what time is it?” you panicked, checking your watch. “Oh… Yeah, we should definitely go back to our dorms.”

“Let’s go then!” Minghao cheered, hooking an arm with yours. “We’ll go together and Mingyu and Soonyoung can go together.”

You nodded before waving to Soonyoung. “Good night. Good job!”

“Yeah…”

“That’s it?” Jihoon was outraged at breakfast. “That was the whole mystery?!”

Soonyoung nodded slowly. “Just Mingyu and Minghao going to Hogsmeade through the back of a statue.”

“Good detective work though!” Mingyu, the man of the hour, cheered him on between bites of porridge. “We went undetected all those years but you found us in two months. That’s impressive.”

“Yeah, but… what do we do with this knowledge?” you wondered. “It was kind of a pointless mystery.”

Soonyoung agreed wholeheartedly. His arms crossed over his chest. “Couldn’t you guys at least have smuggled something in? That would’ve been more fun.”

“Well, I guess we could smuggle you some goods from Hogsmeade every once in a while, in return for not telling on us,” Mingyu suggested, but your partner was having none of it.

He scoffed. “What’s the point of that? I’m not a traitor to my friends.”

“Maybe you could find another mystery to solve,” Seungkwan suggested. “I’ve heard that Hufflepuffs and Slytherins are losing their socks and ties all of a sudden.”

“Oh, yeah,” Soonyoung shrugged, “mine are lost too. I’m barefoot right now.”

You stared at him, wondering what was going through his mind. Was there any thought activity at all?

“Wait!” He jumped up. “That’s a real mystery!”

“With real stakes this time,” Minghao added with a chuckle. “You could become sort of like a hero if you solve it.”

Soonyoung turned to you, a fire lit in his eyes. “What do you say, partner?”

You smiled before extending your hand for him to take. “I’m in partner.”

His cheers echoed in the Great Hall.
