You weren't sure if the door of the former Art Room would be unlocked, you hoped it wasn't.

However, you were disappointed as the doorknob only jiggled. Truth be said, you weren't surprised. It wasn't unusual for the staff to lock this room, away from the public, especially since one of the students were found dead in there.

You silently praised yourself for bringing with you some wire, easily bending the malleable metal the way you want. It didn't take you too long to unlock the door because it was a standard lock which wasn't built in a complicated way. It was one of the very first skills you were taught when you began training years ago.

You made sure to close the door behind you as you slipped through, your eyes taking a while to adjust to the dark room. You were expecting boxes and unneeded furniture because you had heard it was turned into a storage room. However, that wasn't the case.

The windows were boarded down with wooden pieces, blocking any light from outside from peaking through, probably along with prying eyes.

The boxes and furniture were absent as well, the room almost completely bare except the built-in closet at the corner of the room. However, you paid no attention to those details, for now, your eyes zoning onto the middle of the room where a lone vase of pink flowers that were beginning to wilt and one bar of Hershey's chocolate was placed.

You eyed it in curiosity, slowly walking up to the vase, eyeing the variety of flowers that obviously have been there for a while. You were sure they were all quite beautiful at one point, however now they were beginning to shrivel up, the petals of the flowers all in various shades of pink losing some color, the outer edges turning brown.

You crouched down, leaning forward to have a better view of the items placed on the floor. You don't dare touch anything, only pulling out your phone, quickly snapping few photos so you can do some research later. You'll definitely have to look up these flowers later...

Your eyes then moved to the chocolate bar, quite confused on why it was placed there. It was standard Hershey's milk chocolate bar, but you just couldn't understand why it was placed beside the vase. Subconsciously, you run your fingers against the wooden floor, seeing that some parts were stained a dark brown. From your past assignments, you recognized them as blood that soaked into the wood flooring.

So this was where Chou Tzuyu was found with the flowers painted with pig blood...

You were surprised that they hadn't peeled the wood and replaced it. But seeing that it was spread throughout the room, you could understand in a way why they just locked this room up. Financially it may have been cheaper....

You stared down at the flooring, eyeing the stains that were indeed shaped into flowers in disgust. Why did the killer do this? Why did he glorify these girls death like this...? Why use pig blood to paint flowers? Why not just use paint? You were sure there used to be shelfful of them when this room was still the Art Room.

As you're thinking, you feel your heart rate accelerate as you hear the sound of the doorknob being jingled along with the sounds of keys. With wide eyes, you whirl around the room, desperately looking for a place to hide. The only place was the closet that's connected to the wall at the corner of the room.

You cringe as you enter the small space, silently telling yourself that the area was filthy with cobwebs. It's tight, but you fit in barely, closing the door as you tried to conceal your breathing and rapid heartbeat that pounded against your rib cage.

You swallow nervously, using the small air vent on the door to look outside. The space was small, and you couldn't see much, but it was enough for you to hear and see what's going on in the room. But there was no denying it was uncomfortable.

Extremely.

You shifted, trying to adjust yourself to a position that was more comfortable for yourself. However, before you can completely change positions, you covered your mouth with your hand, stopping yourself from letting a sound escape as you recognized the figure who stepped into the room as they turned the light on.

Why was he here? How did he get inside, you made sure to lock the door... Does that mean he has the keys?

The familiar male held two items in his arm, a vase which was very much similar to the one on the floor and a small rectangular candy bar that was wrapped in a brown wrapper. You watched as you held your breath as the man exchanged the vase and the chocolate bar before sitting down where you were investigating moments ago.

He was silent, looking down at the vase of fresh flowers. You squint your eyes to see better but it's no use, the boy's face was blank. However, you were able to see his dark orbs swirling with emotion.

"I brought you some more flowers and your favorite chocolate bar, I know you love these ones...." The boy began speaking as he picked a flower, twirling the stem with his forefinger. "Someone else got killed today. It was Nayeon, she was in the same group as you, right, Tzuyu?"

Hearing the name of the female who died in this room, you confirmed that the male was probably imaging her as he spoke to himself. "I can't believe it's already been a month since you died... I miss you... I regret so many things. There were so many things we could have done. But out of them all I wish we made our relation public, I—"

The male didn't finish his sentence as the door opened, another figure slipping into the room.

His head snapped to the side as he jumped to his feet, his hands curling beside him as he faced the female who walked in with a look of boredom on her face.

You, yourself didn't know what to think. So many questions were running through your head. Listening to him, you realized he was probably in relation with Chou Tzuyu but...

"What are you doing here?" The male questioned her, his voice dripping with disgust that surprised you. You didn't expect that reaction from him. You've seen him interacting with the female multiple of times. You've never seen him like this...

"I followed after you when I saw you sneaking out. Really Daniel? You still come to this disgusting place? Huh, of course, you would, this was the place where you always came to see her. But she's already dead, just forget about her," Rose scowled, eyeing her finger in disgust after she touched the wall, her digit picking up a thick layer of dust.

Daniel looked away from the female, his eyes going back to the vase on the floor, "shut up..."

Rose rolled her eyes before looking down at the floor, eyeing the two items with annoyance. "Oh how sweet, look at you being romantic. Too bad she can't appreciate it because she's already six feet under and rotting away," the orange-haired teenager mocked as she stepped closer to the male until she was directly in front of him. She flashed him a sultry smile as she placed her hand on his chest, "why don't you hang out with someone who's warm and actually has blood running through her? What's the fun being in a room that someone died in?"

Daniel scowled as he shoved her hand away from him, looking disgusted at her touch. Rose obviously didn't like the rejection, snorting as she whirled around her leg connecting with the vase, spilling the water and the flowers onto the floor.

The male silently watched with his teeth gritted as she picked up the candy bar before it got wet, ripping opened the wrapper, taking a bite out of the sweet. Rose's face scrunched up as she spits it out onto the floor, making it land on the floor next to the ruined flowers. "Ugh, why did she even like these? No wonder she was fat," Rose scowled looking at the remaining bar with disgust.

You weren't sure how Daniel still contained his anger as the female continued to disrespect his late girlfriend, his eyes narrowing on his classmate. "Why do you have to be such a bitch Rose? Weren't you her best friend?"

Rose released a snort, crossing her arms over her chest. "Best friend?" She laughed in disbelief, "what the hell are you saying, Daniel? I've never ever even considered her a friend. She was an annoying brat who was using her Daddy's money to buy stuff for all of us. We were just using her."

If you hadn't thought that Rose was a bitch, now you evidently did. She was a fucking bitch.

Rose seemed to find Daniel's anger amusing as she played with a piece of her hair, a thoughtful look appearing on her face. "But aren't I lucky? Every time I begin to think someone is annoying they end up disappearing for me! Today Nayeon was found dead, and recently she was getting on my nerves trying to kiss ass to Seulgi and I. Maybe I have that ability to just kill off useless people with a thought. If that's the case I want the new transfer students gone, they've been getting on my nerve, especially Y/L/N," the female jokingly was saying these, but it made your stomach burn with anger.

How can she talk about a human life that was lost in such a way? Did it not weight anything to her?

And she wants you and Yoongi gone? Please, she wouldn't even be able to a single hair on your scalp before you had her on the ground in a chokehold.

"I would personally fucking kill you if I find out you had anything to do with Tzuyu death..." Daniel growled as he sends a piercing glare at Rose.

Rose seemed slightly surprised at the male's words. However, she was quick to recover, throwing her head back as she laughed loudly seeming indifferent. "Why would I want to kill her? She was my 'best friend' like you said. I still had some purses I wanted her to buy for me, and even if I did, you have no evidence to tell anyone," the female giggled as she threw the half-eaten chocolate bar to Daniel, it hit his chest before falling to the floor. 

Daniel was literally shaking with anger as the female twirled around, mockingly wiggling her finger at the male. "Well, I should get going, I need to check to see if Mina has done the math homework I asked her to do. Talk to you later, handsome."

You silently watched from where you hid as Daniel began to clean up the mess Rose left. You didn't know the boy had this kind of side of him. You had thought that he was a flirty fuck boi with the way he interacted with the girls in the class. You also didn't expect him to actually have a lousy relationship with Rose seeing that the two were civilized in the classroom setting, the boy even hanging out with her group.

You hold back a flinch as the male suddenly chucks the vase to the wall in anger, the fragile glass shattering to pieces before dropping to the floor. His shoulders heaving as he breathes heavily. Destroying the vase doesn't seem to calm down his nerve in any way, it only fueled it even more. It doesn't take long for the boy to rush out of the room, leaving the mess scattered across the floor.

You only come out of the closet, your hiding place when you hear the door gets locked. You heave, coughing slightly, thankful that you were now breathing fresh air as you brush your clothes that are covered in dust. You scrunch your nose, holding in the sneeze that was threatening to spill.

There was no denying that what you had witnessed was interesting. You consider yourself lucky in a way, you had gotten useful information by listening to the conversation. However, you were also disappointed as you realized that the room was cleaned out since the discovery of the body and even if there had been clues left about Tzuyu's murder, it would have been long gone by now.

But now you had some things you had to dig up...
