"Pass!"

The corner of your lips tugged up as you threw the ball between your opponents, the orange basketball easily reaching Yoongi who was waiting for it.

You didn't even bother looking up at the hoop to know the male would make it as he jumped up. You only turn your back, returning to your side of the court with a light jog. And halfway, you hear the familiar swoosh of the ball entering the net indicating another point for your team.

"Nice pass," Yoongi grins as he gives you a high five. His cheeks were flushed with exercise, drenched in sweat, much like you were. He looked like how he usually did when he exercised, and damn, he looked good. But you couldn't help the amusement that danced in your eyes as you eyed the ponytail of his wig, a reminder that he was indeed crossdressing and you were both currently part of a mission.

His lips were stretched into a gummy smile you loved. However, it was quick to disappear and turn into a stoic frown as Woojin rushed to the two of you, his arms getting thrown over both of your shoulders.

"When you said you guys were decent, I actually thought you meant decent! Not fucking amazing!" The male gushed as he excitedly jumped around, shaking both Yoongi and you with his movement. However, he was forced to let go as Yoongi's hand shot out, slamming his hand into the vulnerable stomach of the boy. Woonji doubled over in agony; a pain-filled moan escaped his lips.

"Don't carelessly touch me, you're all sweaty and gross. And I hate physical contacts with guys," Yoongi snottily muttered, giving poor Woojin a look of distaste.

You couldn't help the weak laugh from escaping your lips, not knowing how to feel about the ice princess persona Yoongi was perfectly acting. He was just too good... It almost made you forget that he was actually male...

"Yikes, that's an impressing punch Yoonji-Noona delivered," your eyes shifted to Jihoon who had somehow sneaked up behind you. He flashed you a sweet smile as he handed you a small towel, "Great job, Y/N-Noona. You're great on the court." The boy's smile was so angelic you almost felt like you were temporary blind.

You patted your face with the towel you accepted, grinning at his compliment before your attention moved to Jinyoung who stood a couple of feets away. Throughout the game he stayed out of Yoongi, Woojin, and your way much like Jihoon, only moving when the ball neared him. In the beginning, you could tell Woojin was annoyed that Jinyoung wasn't participating, but the male seemed to forget his irritation as he realized that it was possible to win a game with just you three playing.

Your feet moved to Jinyoung who eyed the other teams playing on the court, deciding to engage the boy in a conversation. However, before you could reach him, your eyes widened, your mouth falling open to yell a warning.

"Watch out!"

Your shout did nothing as you winced, one of your eyes closing in a grimace as you watched the hard orange basketball slam right into Jinyoung's face, making the said boy crumble to the floor. You were the first to rush to his side, helping Jinyoung sit up.

"Fuck, that looked like it hurt," you muttered as you tried to pry the boy's hand off his face. However, when you saw the blood trickle down his chin, you sighed, pressing his hand harder to his nose, making him wince. He looked at you questioning through his teary eye, trying to blink away the pain.

"Wha-"

"Keep applying pressure dummy. We need to stop the bleeding. And don't dare look up, we don't want you swallowing the blood," you're gentle while quick to give out orders as you reposition his hand, not caring as you saw blood get onto your hand.

At the corner of your eyes, you saw Yoongi quickly approaching. However, before he could, you feel another presence beside you.

"Hey, there's nothing for you all gather and see! Go back to your games!" The P.E. Teacher yelled as he knelt beside you and Jinyoung, looking at the two of you in concern.

"Just a nosebleed, sir. But I'll go take him over to the nurse's office and make sure everything is fine. I'm pretty sure nothing is broken, and a nice ice packet will do its work and help with the pain," you good-heartedly explain, smiling brightly at the man who grunted as he eyed both Jinyoung and your hand covered in blood.

The man muttered, "Make sure you go wash your hand properly," before dismissing the both of you.

As you gently helped Jinyoung up to his feet, your eyes met with Yoongi who stood with your team, a look of annoyance present on his face. But he gave you a nod, knowing you were probably going to sneak off to investigate the school a bit after you brought Jinyoung to the nurse.

Yoongi brushed his wigs choppy bangs out of his eyes before he whipped around, Woojin following behind him with sparkling eyes. Jihoon, on the other hand, gave you a small wave and followed behind the two before you left with Jinyoung.

The hallways of the school were empty because classes were still in session and it was absolutely silent except your footsteps because neither Jinyoung or you were trying to make conversation.

The injured boy himself led you to the nurse's office, only stopping once as he waited for you to open the door because he was unable to with his hands being bloody and still attached to his face.

"Oh, my. That's quite a lot of blood!"

Before you could even step in into the room, a female had rushed to the both of you; her painted lips drawn to a frown. Your eyes were quick to take her in, subconsciously raising an eyebrow of doubt.

This couldn't be the school nurse... right?

When you thought about nurses at a school, you always imagined middle-aged to older women with graying hair and gentle smiles. However, the woman before you couldn't be older than thirty and you wouldn't be surprised if she were close to your age. Her makeup was done flawlessly, her clothes hugging her body a bit too tightly and showing a bit too much skin to be called appropriate at a school, a private school if you must add.

Although she had a typical doctor's white coat on, her buttons were open revealing a tight pencil skirt that barely reached her knees. Her blouse was a bright red; her cleavage seems to be peeking out through the free buttons that should have been closed.

The woman ushered Jinyoung to sit in a chair, quickly moving to act. It almost seems like she didn't realize you were there as well, cooing at the injured boy who looked as if he wanted to be anywhere else but there.

"Is it alright if I washed my hands? I got bit of blood on them," you finally speak up, announcing your presence to the woman. She eyed you for a second before nodding, moving to clean up Jinyoung's face that had blood smeared on it.

You held in a scoff as you pumped soaped into you palm, thoroughly washing your hand to rid of any blood that attached to your skin. By the time you were satisfied, Jinyoung was trying to push away the nurse who was placing a packet of ice to his nose.

"Ms. Ahn, I-I can hold the ice myself!" Jinyoung stuttered, looking flustered as the woman placed her hand on his knee.

"Nonsense! And how many times have I told you to call me Nurse Hani, you don't have to be so polite! Anyhow, your hand is covered in blood, and I can't have you ruining my ice pack. Why don't you lay down over there as well, you may get a delayed headache because of the impact. Now be a good boy an-"

You coughed, making the poor boy look up at you in relief while the woman, who you concluded as Ahn Hani gave you a stink eye, obviously displeased that you interrupted her in "helping" her patient.

"Well, I'll be heading back to class now, Jinyoung. Hope you feel better," you smiled at the younger boy as you moved to leave through the door.

"W-Wait, I'll go with you Y/N-Noona!" The boy tried to stand up to escape the nurse's grip, but before he could, the woman pushed down onto his shoulder, forcing him down onto the chair. You send him a smile of pity as he sends you a pleading look, only waving at him as you closed the door.

You shook your head, thinking about the nurse. You obviously didn't like her. She had blatantly ignored you, not even acknowledging your presence and that ticked you off. Where was her professionalism? And the way she acted so sweet with Jinyoung as if she had a motive made you sick. Was she perhaps sexist, you couldn't even believe the way she was so touchy with Jinyoung was even appropriate.

The annoyance you were feeling was quickly pushed to the side as you straighten your back, your eyes becoming serious. You were going to take advantage of being out of class to go dig up any kind of info. And the first place you were going to go was the art room, the place where the third victim, Chou Tzuyu's body was found.

You personally wanted to visit each place where the girls were found to do your own thorough investigation to make sure nothing was left unfound. It wouldn't be unusual for the police to not notice something your trained eyes were taught to find. Even the smallest thing wouldn't escape your eyes and you were desperate for anything. You needed every single information to find the killer of these poor girls.

"I told you to not talk to me ever again, didn't I?!"

You stop, subconsciously holding your breath as you heard a voice from down the hallways in front of you. You pressed your body against the wall, making yourself smaller as you turned the corner to avoid directly meeting whoever spoke down the hallway.

"Y/N-Noona?" You flinched and turned around in alarm to see Jinyoung eyeing you in question. He was no longer covered in blood, carefully pressing a plastic bag to his nose that had a piece of frozen paper towel in it.

He blinked in surprise. He swear you were in front of him but... He gasped, you, who were a couple of feet away from him a mere second ago was now behind him, dragging him into an empty classroom. You brought your finger to your lip, muttering a soft 'shhh' to indicate to him to stay quiet as you forced the two of you to crouch down where you wouldn't be detected.

Seconds later, two forms walked past where you hid. You were quick to recognize the female who stomped down the hallways, trying to walk away from the boy who scrambled after her.

"Nayeonie-Noona!"

The female whirled around, her lips curled up into a snarl. She angrily stomped up to the male, her finger jabbing harshly to the taller male's chest. Her eyes were filled with anger, a look that you were starting to realize was always present on her face.

"Do. Not. Call. Me. That." She hissed as she jabbed him with her finger at each word. "I don't care if I used to let you call me that when we were younger. Here, I don't fucking know you, do you understand me? Don't look at me, don't talk to me, don't come near me when you see me in the hallways. I don't even want to be breathing the same air as you, do you hear me? You and I have nothing to do with each other. And if I ever hear you telling people that we are actually related and were adopted out by different families, I swear I'm going to hunt you down. How the hell am I supposed to keep up my imagine when I'm associated with the nerdiest guy like you?" Nayeon spat out as she glared at the boy who had a heartbroken look on his face.

"B-But..."

"I don't fucking care. Do you know how hard I worked to be included in Seulgi-Unnie's group? I'm not letting everything go to waste by letting people at school know that we're siblings. I hate you, do you understand. Never approach me again, you disgust me."

You winced at the harsh words, feeling pity for the boy who was on the receiving end of it. He wasn't even a bad looking kid like Nayeon said. Sure, his glasses seemed like it was too big and thick for his face and his hair was almost like a birds nest. But he had a cute face and he would definitely be described as handsome if he took better care of himself. And although it's not obvious, you could see the resemblance between the two now that you knew they were siblings.

The poor boy stood by himself in the hallway even after Nayeon was gone, staring down at the floor. But eventually, he turned around with clenched fists, walking away from the scene with heavy footsteps. With him gone, you finally release a breath, letting Jinyoung who was crouching beside you to stand up.

"That was rather harsh, don't you think?" You muttered as you dusted your clothes off. Not that it made such a big difference because it was covered in dirt and sweat from P.E.

Jinyoung looked a bit uncomfortable, rubbing his neck as he avoided eye contact with you. "H-Her whole group is like that... But I didn't know that.."

"Well, I think all those girls should look at themselves in the mirror and see how ugly their personality is if they all act like her. And we should probably keep the information we found out a secret. Poor uh..."

"Lai Guanlin, a first year..."

You raised an eyebrow in surprise, not expecting the shy boy to know the boy who was getting verbally abused by Nayeon. Jinyoung seems to notice your curious gaze, his cheeks flushing as he looked away from you.

"H-He lives two doors down from my room..."

You hum in understanding as you look up at the ceiling. Different thoughts were running through your head, trying to link possibilities. However, your thoughts were cut off as you heard the familiar sound of the dismissal bell, a mess of curses being whispered under your breath.

It looks like your visit to the art room is going to be postponed for now. Especially since...

Your eyes drifted to Jinyoung's awkward, lanky form. You couldn't investigate if he's here with you.

However, you now knew you needed to investigate a bit more about the people who were in this school. Ahn Hani, Lai Guanlin, Im Nayeon... And of course Kang Seulgi's little click of popular girls.

It should start to get interesting....
