"Cheong-san! Look down. Down, down, down!" Su-Hyeok's desperate voice cuts through the air and Y/n only noticed the zombie hanging on Cheong-San's leg. "I know!" Cheong-san shrieked back, weakly kicking on the girl zombie. "Kick her off or something idiot!" Su-Hyeok yells again, but the other boy only got more aggravated. "I'm trying! Can't you see?!" Su-Hyeok looks around for a second and turns his attention back to the boy on the hose. "I'm coming down"

Before Cheong-san could respond, Su-Hyeok leaps from the wall, towards Cheong-san and clings to his back. Y/n chokes on a laugh, forgetting that she was on a wall, and quickly regained her balance. "Hey! Y/n look up!" The shooter turned her head, only to see an infected student about to pounce on her from the upper floor window. "Shit" Without a second thought, the girl also jumped down, latching onto Cheong-san from the front. The teenager blushed a shade of pink as he struggled not to scream having y/n on his waist. "Why can't you just kick her off?!" Su-Hyeok began to climb lower, keeping his hands on Cheong-san's waist as he kicked the zombie off the boy's feet.

"Guys! It's Bare-Su and N/n!" The three sighed with relief, hearing their friends had seen them. "Stop hugging me" Cheong-san said, bringing sly smiles to y/n's and Su-Hyeok's faces. "I'm not hugging you" Su-Hyeok returns, but the other boy scoffs. "Fuck off"

"You like it?" Cheong-San laughs at that, but soon gets pulled off when they reached the broadcasting room. "Are you okay?" Wu-Jin asks when the trio came down, yeeting Y/n inside. The girl was about to answer but Na-Yeon's shouts rang through the room again. "Close it before they get in!" But Cheong-san was only entering while Y/n swore to kill the girl herself if she ever turned. "What's wrong with you? Cheong-san is still out there. You want us just to shut him out?" Gyeong-su asks in anger, disliking the fact that someone expected his friend to be stuck outside. "Is it a crime to want the window closed?" Na-Yeon says it as if it's normal, though she knew she's just selfish. "How can you be so selfish?" Gyeong-su asked, helping Cheong-san inside and moving to the center. "I can't stand you, stupid welfie"

The students widened their eyes at that and Miss Park was cluelessly watching them. "What did you just call me?" Gyeong-su began and pushed Na-Yeon back slightly. "Hey! Knock it off! What's going on here? Guys?" Miss Park interrupts, keeping a hand between the two teenagers. "He hit me," Na-Yeon says, glaring at Gyeong-su who rolled his eyes with annoyance. "Only cause you called me a welfie"

"Is it not true?"

"What's a welfie? Tell me. What is it? What's a welfie?" Miss Park inquires the group of students, who looked away at the teacher's stare. "A person on welfare. 'Welfie' for short" Y/n blankly answers, closing her hands together to dissuade herself from whacking Na-Yeon. Apparently, Wu-Jin taught her that; whenever she was angry, Y/n teds to do things without thinking and that was his treatment. "Na-Yeon, that was wrong. Don't ever say that again. And Gyeong-su. When you hit people, you're the one who ends up losing. Do you understand?" Miss Park scolds as politely as she can, considering the situation they are in right now.

"No, I don't"

"Listen, we can't be fighting each other in a moment like this. We don't know what's going on out there with those..." Miss Park is still unable to complete her words, unwilling to call her students monsters. "Are they zombies? What about the other teachers? Has anyone called the cops?" Su-Hyeok asks from behind the teacher as she turns around to face him. "Don't worry, I'm sure someone already has. I just don't have my phone on me, right now"

"We called them, but they're not coming. Neither the police nor first responders" Cheong-san spoke up, resting his back on the window. "Hey, they still work right? The internet" Joon-Yeong pipes in, walking towards the computer on the table in the middle. As the group huddled around the computer, y/n sat down on the cold floor, placing her bag in a corner and leaning on the audio controls. Wu-Jin moves away from the group, sitting next to the girl. "I'm tried" Y/n speaks up, knowing all too well the boy was going to question her condition. Wu-Jin sighs softly, placing an arm around the shooter and resting his head on hers. "Don't worry, you'll get to sleep after we're safe"

"I will?"

Wu-Jin smiles, nodding his head before he felt Y/n shift around, standing up to her feet. "Until we're safe, I'll try my best to protect you!" Wu-Jin chuckles, standing up and patting the shorter girl's head. "No, you'll look after yourself" Y/n rolled her eyes, crossing her arms as she stared at the boy. "As if you're not a hero Wu, you'll end up jumping in front of someone to save them and you'll let yourself get bit. I've known you for years dumbass" Wu-Jin grins again, but the moment gets cut short when the window breaks and shards of glass fall inside. "Ouch" Y/n winces, feeling a harsh sting on her nose.

"What the hell. What was that?" Joon-Yeong asks from before the computer, as the group turns to the now broken window. "You're bleeding" Wu-Jin quietly says before raising his hand to wipe the blood off y/n's nose. However, the girl stops him, pointing at his already bloodied sleeve. "That's the blood from infected students, I might get infected with that blood" Wu-Jin nods at the girl with awareness, both failing to notice a particular pink sweater eavesdropping.

The hose hanging from the science lab swung back and forth, hitting the rest of the glass. "Did someone not make it?" Hyo-Ryung asks in her usual anxious voice, but Dae-Su was quick to deny it. "Yah! Don't go any closer!" Gyeong-su shouts as he sees Cheong-San heading to the broken window. "Be careful!"

As soon as the teenager reached the window and glanced out, a female zombie hangs down from the hose and reaches out to him. "Shit! It's coming in!" Ji-Min screeches while the infected waves its hand around. Cheong-San takes a few steps back and grabs the mop next to the glass shelf. The students began to chant 'push it off' like in a cult until the mop broke and the infected held it in her grasp. Su-Hyeok moves forward and yanks the mop back, stabbing it in the zombie's neck. Nonetheless, it remained alive but less violent. Y/n took notice and stepped up to shoot it down, but Gyeong-su butted in, pushing it off. Nonetheless, it stayed and clasped Gyeong-su's hand.

Y/n instead grabs the tumbler on the table and hits the infected female's hand as it leaves Gyeong-su, who took the chance to unplug the monitor and smash it on the zombie. "That was close" Dae-Su sighs as both the monitor and the girl hit the ground, deteriorating into pieces. "Where did it come from" Wu-Jin asks no one in particular, not comprehending how it managed to climb a hose. "Might have accidentally fallen over, pass me my bag" Y/n states before showing her hand to Nam-ra, who swiftly passed it on.

"Gyeong-su, your nose is bleeding" Joon-Yeong speaks up as the teenagers turned their attention to the boy. "Really?"

The next fifteen minutes were spent on Na-Yeon accusing the boy of being infected, while the truth was himself being hit by the mop. Regardless, due to Gyeong-su's stubborn attitude, he had compelled himself to quarantine for one hour. He was seated in the recording room, while the other students viewed him through the mirror, like he was an animal in the zoo. "He's stubborn huh" Joon-Yeong says as they proceeded to watch him. Y/n was seated at the table next to Wu-Jin, who was busy choosing an appropriate band-aid for Y/n and Gyeong-su. The girl had a small first-aid kit in her bag, that only held a little amount of stuff.

"I'm thinking you're not the one who bought this" Wu-Jin says as he finally chose a band-aid, smiling at the Pikachu-themed one. "Jae-Ik Hyung bought it" The short-haired girl sighed, recalling how the male had taught her the importance of having a small emergency kit. Wu-Jin smiles again, peeling the band-aid and placing it on Y/n's small wound. The boy let out a laugh, unable to hold it in. Seeing his best friend wearing something cute for the first time sure warmed his heart. "Oh shut up Wu"

"What do you think?" Dae-Su suddenly asks Y/n who gave the boy a confused look. Both she and Wu-Jin were deaf to the conversation going on between the others. "About the zombies' weakness" Both of them make a knowing face and address the group of teenagers. "I think they are drawn to smell, that's why they follow you" Wu-Jin commented, smirking at Dae-Su who returned an offended glare. "I don't smell, I just sweat" Wu-Jin mocked the boy further, but halted when Cheong-San spoke up. "I think they are more sensitive to sound than smell"

"Sound?"

"They can see too, Coz they tend to reach out their hands before attacking. But if they can't smell, how do they distinguish zombies and humans? I mean, they're not eating infected ones" Y/n speaks up, resting her chin on top of her hands. The others scratched their heads in thought, unable to come up with more theories. Y/n slumped back into her seat and took out her phone from under the table, it only had three percent of charge left. Opening the gallery in the device, she began to skim through the photos she had taken. From Mr.Kang to Min-Ji and their ways of turning. "I thought you lost it, Pikachu" Y/n squealed quietly at the sudden voice, but calmed down once she knew it was Nam-ra.

"I don't have my charger, it's similar to losing my phone and don't even start with the Pikachu" Nam-ra chuckled, turning silent as she sat next to the shooter. "Nam-ra?" The class president looks up, staring at the shorter girl. "I'll try my best to protect you, but if you get bitten, please try to fight it... Coz I can't lose you"

Nam-ra smiles a subtle one, grabbing ahold of y/n's hand. "I'll fight it as long as you don't sacrifice yourself, I feel like you might do it" Y/n laughed at that, an awkward one since her bestie caught her. Y/n would've sworn to protect everyone until they reach somewhere safe, but getting a chance to die that does not require blame was an attractive choice for her. The gold medal winner with rich parents, kind-hearted best friend, and supporting neighbor, that was who y/n was to everyone. But for herself, she was an unlucky teenager with busy parents, a lonesome apartment, and training.

Y/n slowly turned her attention towards the recording room, watching Cheong-san goof around with Gyeong-su through the closed door. The girl smiled fondly, witnessing their friendship for a long time ever since she moved to Hyosan.

"You remember your promise, right? After 30 minutes you'd apologize" Miss Park suddenly speaks up, reminding Na-Yeon of the promise she had made. Though the situation was amusing to Y/n she was unable to understand why Nam-ra looked troubled about Na-Yeon going inside. The students were unaware of the losses they are gonna face, watching Na-Yeon and Gyeong-su interact inside the recording room. While the others were unable to hear their talk and were cheering them to kiss, y/n was convinced that they were fighting again.

However, the fight wouldn't end nicely, unknown to them.
