As Na-Yeon and Gyeong-su burst out of the recording room screaming profanities at each other, the others were quite puzzled. Y/n felt a new wave of a headache arriving, watching the two fight for the hundredth time. "I guess I was right after all" Na-Yeon abruptly piped up, scowling at Gyeong-su. The teenagers overlooked the boy staring as blood trickled from his nose. "Gyeong-su..."

"Hey hey, what's wrong with me? Something's wrong" Gyeong-su muttered, gazing at his hands as he wiped off the blood from his nose. "It's not true" Cheong-san says, tears brimming in his eyes. "Come on! Throw him out! Throw him out now!" Na-Yeon began her daily dose of whining, but the students and Ms.Park were extremely startled to listen to the girl. "I'm not... I swear I'm fucking not!" Gyeong-su yelled, shaking with fear as his eyes proceeded to engulf a red tint. "Stay where you are. Stay back"

"Please, stay back" On-Jo whimpers as she moves backward, in fear of getting bit. Gyeong-su stops panicking around, looking at Cheong-san who spilled as many tears as himself. "I've turned, right? Cheong-San what should I do?" Y/n bites her lower lip, unknowingly tears were filling her open eyes too. The reality that a few moments ago she looked after the two boys play around, and now sobbing felt like a stab to her soul. Y/n glanced away, outside the window, trying not to watch whatever happens to Gyeong-su. Not because she doesn't care about the pain he'll suffer, but to ignore the pain of losing a friend like many others had to go through.

"What are you doing? Kick him out. We're all gonna die if not!" Na-Yeon's voice pulls y/n back from her thoughts and forces her to turn back. "I can- I can leave on my own" Declares Gyeong-su, staggering to the door, occasionally hitting himself on the tables. "No- wait Gyeong-su-" Y/n suddenly speaks up, losing control of her body as she grabbed the infected boy's hand. When she swore she won't see him turn, y/n was only deceiving her selfish side. She wanted nothing more than to spend the last moments with her friend. Gyeong-su turned back, smiling at the girl with wet eyes. "There's nothing you can do for me Y/n... But thank you for befriending a loser like me. Thank you" Y/n was pulled back by Ms.Park while Gyeong-su fell to the floor, unconscious.

Gyeong-su turned, he growled at the group with hunger, stumbling around to capture prey. It looked like he was fighting the infection, that was inevitable to his susceptible heart. A familiar tune of Auld Lang Syne rang in the broadcasting room and Gyeong-su turns to Cheong-San, who smiles at the boy and resumed whistling the tune. He was seated on the open window sill, tears no longer streaming as they stained his bloody cheeks. The other boy groaned, cracking his neck as he dashed from his stance. Cheong-San jumped inside through the other window, watching Gyeong-su's body fall outside and run away to the darkened school grounds.

The room was quiet again, but no one was smiling or chatting like a few minutes back. Y/n and Cheong-san were at the windows, looking at the night sky void of stars. Dae-Su was crying rivers next to Joon-Yeong and Wu-Jin who attempted their best to reassure the taller boy. Ji-Min was patting Hyo-Ryung's back as the girl looked too traumatized to speak or respond. "I told you all. He was infected. Well, are you happy now? You were all wrong. Only I was right. What would you even do without me?"

Y/n rolled her eyes, turning around to face Na-Yeon and hopefully shove something up her mouth. However, her bestie beat her to it. Nam-ra rose from her seat standing opposite to Na-Yeon with fierce eyes. "I know you did it" Na-Yeon gives the class President a taken aback expression, and scoffs. "I didn't do anything to Gyeong-su"

"I didn't say anything about Gyeong-su" Everyone's attention was on the two girls, but mostly on not needing another round of the fight. "While we were all watching Gyeong-su, you were alone in the back" Na-Yeon backs up a little as the others seemed to keep their attention on her. "You wiped that blood with your handkerchief. And wiped that on the scratches on Gyeong-su's hand" Nam-ra stated in her calm voice, gesturing to the mop Su-Hyeok used to stab a zombie, although she was angered at the other girl's actions. "I did not!" Na-Yeon shouts with an erratic voice, almost shuddering with panic. Y/n moves to the mop and takes it in her hands and shows it to the group. "The blood is smudged here" Cheong-san eyes the bloody mop for a second, turning to Na-Yeon and Nam-ra with an indistinct expression.

"It's in your pocket, take it out" Nam-ra reaches out her hand to take out the handkerchief, but Na-Yeon instantly took it, throwing it on Nam-Ra's body. Y/n smiled at that, seeing how impressive her best friend was. "Nam-ra, do you realize what you're saying right now? If that is true, it means Na-Yeon killed Gyeong-su" Ms.Park butts in, staring at the class President with concern, half of her wanting to turn away, and let Na-Yeon sprout out whatever she did, but the teacher side of her personality wanted them to stop, to be normal students and carry on with survival. "It's true, Na-Yeon did it, she killed him"

"That's Gyeong-su's blood on it" Na-Yeon argues, pointing at the kerchief in Nam-Ra's hand. Y/n pushes past Dae-Su, taking the kerchief from Nam-ra and shoving it in Na-Yeon's hand. "If a scratch still bled like that after thirty minutes, I'd like to see you wipe it on your scratch too" Said the shorter girl, smiling as she nudged her head downwards, directing at the minor scratch on Na-Yeon's leg. "Like his blood is so clean? Fuck he was a zombie!" The group looks at the girl with shock, almost fixing in their hearts that she indeed was behind Gyeong-su's death. Na-Yeon crouches down and holds the kerchief to her wound, but does not wipe it. Ms.Park jumps in and grabs her hand, giving Na-Yeon a chance to pretend that she was going to wipe it on her scratch. "Give it to me!"

"Leave me alone! fսck! I should just die too then, huh? That's what you want, isn't it? Why is Gyeong-su better than me? That dirty welfie pushed me" Says Na-Yeon, crying as she sat on the cold floor. "How could you just fucking..." Cheong-San trails off, the tears that had stopped a while ago, returning. "I didn't kill him, okay? Gyeong-su fell, but he got up and ran. He's still alive. He didn't die, he just turned"

The next few moments were hazy, as Cheong-san had slapped the girl across her face, addressing her as a murderer. The next thing was more shocking as Na-Yeon ran out to the hallway, shouting how she had no friends. "Listen... No matter what happens, you stay alive. Also, you must never take a life. If you cause someone else to die, life becomes completely meaningless. All right?" Ms. Park says, leaning against the closed door which Na-Yeon used to exit. Before the students could comprehend the circumstance, Ms.Park rushes out, closing the door shut. Dae-Su tries to go after her but was held back.

Y/n slumps down on a chair, holding her head in her hands. When she found everyone safe, she thought everything will be okay, that all of them will stay alive and survive. However, one by one everyone was dropping dead, and she couldn't help but think maybe it was her fault. Wasn't y/n the toughest out of them all? Wasn't she clever like Nam-ra? Then why couldn't she prevent this? Why was she powerless to save them? Why was she so useless?

The noise of a helicopter whirs around the school, as a huge white light was shined on the broadcasting room. Y/n felt the light red through her closed eyes, feeling Wu-Jin's hand resting on her shoulder.

"I didn't hear anything after Na-Yeon and Ms. Park went out" Cheong-san says, leaning against the window where On-Jo had attempted to comfort him. "You mean, screaming?" Ji-Min asks, playing around with a whiteboard marker. "Maybe they didn't die, then. They wouldn't have been quiet if zombies were biting them. They must be alive" Dae-Su speaks up, looking at his fellow peers. He sighed when no one made a sound, lost in their thoughts. "Why won't you respond? No one answers me. I'm always talking to myself"

"I think you're right" Wu-Jin says with a smile, tapping the boy's shoulder. Dae-Su rolls his eyes before swatting his hands away. "It feels weird to ask this, but does anyone wanna go to the bathroom?" Su-Hyeok started after a long period of being quiet. Soon enough, with On-Jo's help from her previous learning lessons from her dad, the group succeeded in making a temporary toilet.

"Do you have any idea what's going on out there? You gotta tell me what you know" Jae-Ik asks as he dashes inside the questioning room, glaring at the science teacher. "The strong are now ripping apart the weak. It happens all the time" Blankly declared Byeong Chan. "Are you crazy?!" The teacher meekly sighs, leaning back on the iron chair that has turned warm after hours of sitting on it. "Why did you do this?!" Jae-Ik asks again, frustrated by the ambiguous and unnecessary answers from the teacher. Byeong Chan scoffs at the question. "I tried to tell you, but no one listened to me. My son was bullied for a very long time. I only found out when he tried to kill himself. It was too late. But I still thought I could fix it"

"We transferred him immediately pretty much to run away. And they kept finding him and harassing him. I guess it was fun for them. Like they're playing with a toy" Byeong Chan sharply exhales, leveling his eyes with the furious detective. "That's when I realized it. We live in a system of assault. A complete nobody like me... can't change the system. So I decided to change my son. I just hoped he wouldn't die. I didn't want him to try and commit suicide again" Jae-Ik slammed his fist on the iron table, his breath trembling with the quantity of anger he had inside. "You... You created a monster"

"That's how desperate I was to save him. Rather than die as a human, I wanted him to survive as a monster"

Jae-Ik soon brought Byeong Chan outside, moving to evacuate the city. However, the police station was also broken in with zombies cheerfully munching on policemen. Jae-Ik goes around to help his colleagues, whacking the zombies with his baton. "My laptop is in the school science lab. If you try to find a solution to all this in there, that's the only way" Byeong Chan unexpectedly says as Jae-Ik looked at the man with bewildered eyes. He stood to his feet, blind to the zombie dashing to him from behind. "So let's go get your laptop. Come on. Let's go" However, Jae-Ik falls to the floor, being pushed by Byeong Chan, who was being devoured by the swarm of infected. "Damn it. Byeong-chan!"

"Go! Get out of here!" And so, Jae-Ik escaped, setting his mind to recover the laptop.
