Y/N and Su-hyeok raced down the stairs, desperately trying to avoid the zombies that were close behind them. Their feet came to a sudden halt when they found more of the creatures stumbling towards them from the lower staircase, realizing they were trapped. Su-hyeok's hand tightened around Y/N's as he began to drag her down the corridor, when a group of zombies emerged from one of the classroom's, cutting them off from all sides.
"Su-hyeok!" Y/N cried, spotting a store room door half open, making a run for it.
The pair raced into the small room, slamming the door behind them just before the zombies could reach them. Y/N gulped as she heard them banging from the other side, watching as the wooden door creaked, looking as if it was seconds from shattering. A loud scream from outside had the banging noise stopping, as they could hear the zombies sprint off in the direction of the sound. Y/N let out a sigh of relief, her heart still racing, amazed they had managed to make it out alive. Just as she turned to face Su-hyeok, his hand suddenly clamped down over her mouth, muffling the gasp that left her lips. He pulled her against him, his eyes wide as he stared at something on the other side of the room. Y/N's movements stilled as her gaze fell on a student lying on the floor, facing away from them, a pool of blood underneath them. Y/N felt Su-heyok pull the knife away from her hand, as he slowly pulled his hand away from her mouth, knowing she had now seen the risk. Cautiously, he began to approach the motionless figure, his hands shaking a little. They both jumped back in surprise when the girl rolled onto her back, a terrified look in her eyes.
"H-help me..." She trailed off, holding her hand out.
"What happened to you?" Y/N asked, coming to stand beside Su-hyeok.
"I tried to run but...it's bad, isn't it?" The girl sobbed, looking down at her leg, which they could now see had a chunk of flesh missing from her shin.
"You were bit?" Su-hyeok gaped, his tone full of panic.
"I got away. I thought maybe I...I don't want to die" The girl started to whimper, as Y/N took a step forward, much to Su-hyeok's surprise.
"Does it hurt?" Y/N questioned, crouching in front of the girl, earning a nod in response.
"I can make it stop hurting" Y/N offered, watching the girl's eyes widen.
"I'm scared" The girl murmured, as Y/N reached out to take her hand, hearing a sound of protest from Su-hyeok.
"I'm right here" Y/N exclaimed, keeping her eyes on the girl, as she raised her other hand in the air, gesturing to Su-hyeok to hand her the knife.
"Y/N...are you sure?" Su-hyeok questioned, handing her the knife nonetheless.
"I've got this. Don't worry" Y/N told him, hoping he didn't hear the shakiness to her voice.
She grimaced as the poor girl started to shake, blood beginning to coat her lips as she coughed, clearly in agony. Her eyes had become bloodshot, and her breathing laboured. It was horrible to see.
"What's your name?" Y/N asked, turning her attention back to the young girl.
"N...Nari..." The girl stuttered, as black veins started to rise over her neck.
"You did good, Nari" Y/N told her, squeezing her hand.
"I did?" The girl mumbled, as a tear dropped down her cheek.
"Yeah. You did. Now, close your eyes. Take a deep breath" Y/N went on, as the girl did so, not seeing how Y/N raised her other hand over her head.
"I'll see you on the other side" Y/N exclaimed, watching the girl's lips twitch into a sad smile.
A second later, she brought the knife down onto the girl's head, killing her instantly. Her hand that had been holding Y/N's, flopped to the ground, the smile still on her face. Y/N pulled the knife out, her bottom lip trembling when she saw the blood now splattered over her hand. She flinched when she felt a hand touch her shoulder, looking up at Su-hyeok with watery eyes. He was looking at her strangely, an expression on his features she had never seen before. It was almost like...admiration?
"What?" Y/N frowned.
"I was just thinking...about how proud of you Cheong-san must be" Su-hyeok replied, earning a small scoff from her.
"Not after all the screw ups I've made" Y/N muttered.
"You seem pretty amazing to me, Y/N" Su-hyeok smiled, as the blush slowly rose back on Y/N's cheeks.
ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ---------------------------
The rest of their group had made it to the Science Lab and were busying barricading the broken windows to stop the zombies from getting in, when Cheong-san felt his heart stop. His eyes darted around the room for his sister, his mouth going dry as panic took over him.
"Y/N? Y/N! Where is she?!" Cheong-san exclaimed, as his classmates froze.
"She was with..." Dae-su trailed off, as a realization hit him.
"Su-hyeok. He's...he's not here either!" On-jo cried, turning to Cheong-san.
He had been so preoccupied with getting On-jo to safety that he had forgotten to keep his eye on his little sister. And now she was gone. What if she was already...
"I have to go get her" Cheong-san announced, rushing towards the barricaded door.
"You can't, Hyung! If you go out there, you'll die!" Gyeong-su warned him, grabbing the other's boy's shoulder.
"I don't care! I'm not leaving her!" Cheong-san yelled, as Dae-su rushed over to him.
"I'll come too" Dae-su informed them, hearing a harsh scoff from the other side of the room.
"Why bother? They'll both already be dead" Na-yeon pointed out, watching a furious expression grow on Cheong-san's face.
"Don't you dare say that!" Cheong-san shouted, as On-jo pushed herself in between the two.
"I want to go too, Cheong-san but...they'll get in if you open the doors. We'll all die" On-jo explained, as he turned to the dozens of zombies already trying to break through.
"Su-hyeok will look after her. They'll come back. I'm sure of it" Nam-ra insisted, as Cheong-san clenched his jaw, but reluctantly nodded.
"If something happens to her..." Cheong-san trailed off, with a sob.
"Y/N can handle herself, right? She's been looking out for you for years. She can handle a few zombies" Gyeong-su said, in a comforting tone, squeezing his friends shoulder.
ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย -----------------------
Y/N had opened the window of the store room, looking out at the steep drop below, feeling herself growing dizzy. She shook her head, looking at the next floor up, where she hoped her brother would be. They hadn't heard any other screams, and she had faith in Cheong-san. He was more resourceful than people gave him credit for.
"Here" Su-hyeok murmured, coming to stand beside her.
"You found water?" She gaped as he opened a water bottle.
"There's a box of supplies down there. It's not much, but we can pack it up and take it with us when...you should watch the blood off your hands" Su-hyeok explained, as Y/N bit her lip.
"We shouldn't waste the water--" She began, but Su-hyeok reached down to pick up her hand, already pouring the cold liquid over her knuckles.
Her lips twitched into a smile as he cleaned her hand, his fingers brushing over her skin, cleaning away any of the dried blood. Once her hand was clean, he still kept holding on for a few seconds longer, a nervous expression having grown over his features.
"So...you never said. Why'd you bring a knife to school?" Su-hyeok inquired, reluctantly dropping her hand.
"Protection" Y/N shrugged, dismissively.
"From someone in particular?" Su-hyeok frowned, when Y/N wouldn't meet his eyes.
"...Taehyun Choi. I sort of...beat him up last month" Y/N admitted, hearing a laugh leave Su-hyeok's lips.
"Sort of?" He asked, as her lips twitched into a smile.
"I beat him to a pulp" She grinned, as he shared the expression.
"He had been bullying Cheong-san. He started hitting him...I couldn't let the bastard get away with it. But now I think he's had someone following me" Y/N admitted.
"Ah. So, you brought the knife in case you were attacked" Su-hyeok realised, as she nodded.
"I just didn't count on the attacker's turning out to be zombies" Y/N mumbled.
"...You're not freaked out? Most people don't want anything to do with me when they find out" Y/N stated, as Su-hyeok shrugged.
"You were just protecting your brother. Besides, it's..." Su-hyeok trailed off, with a smirk.
"What?" She inquired.
"Nevermind" Su-hyeok mumbled, smiling to himself.
"You keep doing that. Not telling me what you're really thinking" Y/N went on.
"I don't think Cheong-san would like me flirting with his sister" Su-hyeok exclaimed, as Y/N's mouth went slack.
"Well...he's not here right now, is he?" Y/N replied, quirking an eyebrow, as Su-hyeok bit his lip.
"You're definitely trouble, Y/N" Su-hyeok murmured, his eyes flickering down to her lips, as she felt her heart beat quicken.
Just as Y/N opened her mouth to reply, they heard a loud beeping sound, causing them to freeze. Their eyes flickered to Nari's body, seeing her pocket was lit up, a phone clearly inside. Y/N raced forward, grabbing the phone and answering the call, only for the battery to die a second later.
"Fuck!" She exclaimed, angrily.
A second later, the banging was starting on the store room door again, the zombies clearly having heard the phone. Su-hyeok was quickly grabbing the box of supplies and chucking them into Nari's discarded backpack, knowing the door wouldn't hold for long. The banging got louder and louder, as Y/N watched in horror as it started to splinter. Su-hyeok slung the backpack over his shoulder and grabbed her wrist, pulling her to the window, as he jumped onto the windowsill.
"You can't be serious!" Y/N gaped.
"It's our only way out" Su-hyeok pointed out, as Y/N shook her head venhmently.
"Okay, well I'm just gonna' stay here--" Y/N began, as Su-hyeok cut her off.
"Y/N! We need to go. Now!" Su-hyeok insisted, still holding onto her wrist.
"Is this a bad time to admit I have a fear of heights?" Y/N grimaced.
"Shit, really?" Su-hyeok mumbled, as the younger girl let out a groan.
"It's never really been a problem, okay?!" Y/N exclaimed, hearing the door creaking from behind her.
"Hey, you trust me, right?" Su-hyeok asked, as Y/N nodded slowly.
"I won't let anything happen to you, Y/N. I promise. I won't let go" Su-hyeok told her, reaching down to take a hold of her hand.
Giving a panicked nod, the pair climbed out onto the window ledge, as Y/N's eyes widened when she looked down to the ground below. Su-hyeok kept his hand tightly wrapped around hers as he pulled her along until they got to one of the outside beams. He went first, grabbing onto the other side of the beam and having to make a small jump over to make it.
"Shit, shit, shit" Y/N whispered, her hands beginning to shake as she looked down again.
"Just keep your eyes on me, Y/N. You're doing great" Su-hyeok exclaimed, when they heard a crashing sound from inside the room, followed by racing footsteps.
Knowing she had to jump over the beam or become zombie food, she rushed forward, almost slipping on the window ledge, as Su-hyeok's other arm reached out to grab her waist, keeping her steady. He held her close to him for a moment, watching as the zombie's began attempting to crawl out of the window, but they were now safely on the other side of the beam.
"Thanks" Y/N sighed, as he looked down at her with a grin.
"You're pretty cute when you're scared" Su-hyeok smirked , as she nudged him with her elbow.
"Stop being a tease" Y/N giggled, having almost forgotten the position they were in.
"Come on" Su-hyeok grinned, moving his hand from her waist back to her hand and dragging her along the ledge.
He frowned when they came to the next beam, which was far bigger than the last one and also had a rain gutter in the way. He tried to lean over the beam, pushing his leg out onto the next ledge, but lost his footing and would have slipped off if Y/N hadn't grabbed his jumper.
"Fuck. We can't get across" Su-hyeok mummured.
"Maybe we can go up--" Y/N began, when there was a loud crash from across the ledge.
Her mouth dropped open when she saw none other than her brother falling out of the classroom window, a group of zombies following him a second after. She let out a gasp as she watched him grab onto a hose that had been tied together and was now hanging out the window. Her eyes widened as a female zombie grabbed onto his ankle as they fell, now attempting to claw at his leg.
"Cheong-san!" She cried, as her brother's eyes flickered up.
"Y/N?! What are you doing there?" Cheong-san gaped.
"Me?! What are you doing? Hit that bitch!" Y/N insisted, gesturing to the zombie holding onto him.
"I'm trying!" Cheong-san huffed.
"Shit, I'll come across to you" Y/N exclaimed, ushering for Su-hyeok to try to climb over the beam again.
"No. Don't" Cheong-san shook his head, trying to throw the zombie off still.
"We're coming. Don't argue" Y/N told him.
"You should be the one listening to me. I'm the older sibling, Y/N" Cheong-san retorted, repeatedly slamming his foot down onto the zombie's hand.
"And I'm the smarter sibling, but you don't hear me go on about it, do you?" Y/N muttered, earning a soft chuckle from Su-hyeok at their antics.
"It's not funny, Bare-su!" Cheong-san groaned, as an idea popped into Y/N's head from hearing the nickname.
"That's it!" Y/N exclaimed, grabbing onto Su-hyeok's shoulder, as she leant down to pull one of her shoes off.
"Hey, bitch!" Y/N yelled, as the zombie's head shot up.
It was then met with a flying shoe a second later, hitting her directly on the nose as the zombie lost it's grip on Cheong-san and fell to the ground below. Cheong-san let out a breath of relief, looking up to find his sister giving him a thumbs up.
"What would you do without me, brother?" Y/N called out, as Cheong-san froze for a moment, before shaking his head and descending down on the hose.
"We're in the recording studio. You can jump and grab this, right?" Cheong-san asked, earning a quick nod from Y/N.
"Yes. Just get in the room before you fall!" Y/N insisted, watching her brother reluctantly crawl into the recording studio.
"...I defintely can't jump that far, Su-hyeok" Y/N murmured, catching his eye.
"You're the bravest girl I know, Y/N. You can do this" Su-hyeok stated, as she gave him a look.
"You're resorting to flattery now? We really must be fucked" Y/N sighed, leaning forward to take a closer look at the hose.
"You go first" Su-hyeok insisted, as Y/N began to shake her head.
She froze when Su-hyeok suddenly leant forward to press a soft kiss to her cheek, biting his lip as he pulled away, their eyes connecting. A second later, he was grabbing her waist and all but throwing her across the ledge as she let out a scream, reaching out to grab the hose. Her heart was threatening to beat out of chest as she opened her eyes to find that she had managed to grab one of the loops on the hose and was now just hanging on.
"You fucker!" She screeched, hearing Su-hyeok laugh.
"Y/N?! Are you okay?" Cheong-san called out, looking up to see she had made it.
"I'm just great" Y/N grumbled.
She looked back up to Su-hyeok, ready to curse him out, when she spotted something above him. A snarling zombie was crawling out of the window directly above him, causing Y/N to let out a gasp of horror.
"Su-hyeok! Above you!" She yelled, as his head snapped up, just as the zombie drool dropped onto his cheek.
A second later, he was jumping across the ledge, just missing the zombie that had been hurtling out of the window towards him. He managed to grab the hose about a metre above Y/N, his legs kicking her in the back, as she let out a yelp.
"You could have tried to catch me, Y/N" Su-hyeok teased, as he began crawling down to her.
"I can't save you all the time" Y/N grinned.
Su-hyeok let out a cry a second later as a zombie's hand suddenly waved in his face, from the classroom Cheong-san had jumped out of. Su-hyeok quickly jumped down on the hose, scared of getting scratched, wrapping his arms around Y/N's shoulders.
"Fuck, you're too heavy, Su-hyeok!" Y/N complained, feeling how her shoulders strained under his weight.
All of a sudden, the hose dropped down further, as Su-hyeok lost his grip. He grabbed onto her jumper, before moving his hands to wrap back around her front, letting out a sigh of relief as he thought for sure he was about fall to his death.
"Uh, Su-hyeok?" Y/N mummured.
"Yeah?" Su-hyeok replied, looking down at the zombies below.
"You should probably move your hand" Y/N blushed, as Su-hyeok leant forward to see what she meant.
His mouth went slack when he realised he was groping her chest, able to feel her bra under his hand, quickly pulling it away a moment later. He pulled himself up, reaching out to grab the hose just above her hands, his cheeks a bright red color. He scrunched his eyes shut as he desperately tried to think of something else, when he heard Y/N begin to laugh.
"Are you getting hard right now?" Y/N giggled, feeling something pressing against her ass.
"...Oh, shit. Uh...sorry..." Su-hyeok mumbled, looking down to find she was right, feeling his cock straining against his trousers.
"So...just to clarify, it's me doing it for you, not the zombies trying to eat us, right?" Y/N teased.
"You're unbelievable" Su-hyeok huffed, shaking his head, fondly.
"You certainly seem to like that" Y/N smirked, arching her back a little, pushing her ass against his groin.
"Fuck, don't do that" Su-hyeok bit his lip, finding himself growing harder.
"Sorry" She laughed, a smug expression growing on her face.
"Are you two coming down or what?!" Gyeong-su called out, as the pair's eyes widened, realizing they had completely forgotten where they were.
"Uh...we're going to stay up here for a bit longer" Y/N announced, after she heard Su-hyeok gulp.
"Why?" Gyeong-su questioned.
"No reason!" Su-hyeok exclaimed, in a strained voice, scrunching his eyes shut.
"So...how long do you think it's going to take for your, uh...problem to go away?" Y/N asked, a moment later, as he let out a loud moan.
"You're enjoying this, aren't you?" Su-hyeok complained, dropping his head onto her shoulder.
"You're the one moaning" She grinned, earning a kick to her shin.
ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย ย --------------------------------
A little while later, the pair climbed down into the recording studio, greeted by many relieved faces. It was then that Y/N realised that her fear of heights had certainly lessened that day. A hand reached out to pull her in, as Y/N looked down in surprise to see it belonged to Nam-ra. She held on tightly as Y/N jumped down to join her, a worried look on her face.
"Are you okay?" Nam-ra questioned, causing a smile to grow on Y/N's face.
"I'm good. Are you? No one got hurt did they?" Y/N asked, as Nam-ra shook her head.
"I was just...we were worried about you two" Nam-ra admitted.
"I was in good hands" Y/N shrugged, eyes flickering to Su-hyeok's as he was dragged in by Gyeong-su and her brother.
"I didn't have time to say before, but thank you for standing up for me. You didn't have to" Nam-ra stated, shyly.
"It's okay. And, uh...thanks. You know, for worrying about me" Y/N replied, as Nam-ra looked down to the floor with a smile.
A moment later, a hand was slapping her shoulder, as Y/N whipped around with an indignant cry to see her brother glaring at her. Before she could shove him back, he was pulling her into a tight hug, dropping his chin onto her shoulder, breathing shakily.
"I thought I lost you" Cheong-san murmured.
"Don't be so dramatic, idiot" Y/N giggled, hugging him back just as tightly.
"You're not leaving my sight again, okay?" Cheong-san all but ordered.
"Yes, sir" Y/N replied, pulling away to give him a mock salute.
"Where's your shoe?" Dae-su asked, noticing she only had one on.
"Turns out they're pretty good zombie weapons" Y/N laughed, deciding to pull off her other shoe.
All of a sudden, a fight broke out between Gyeong-su and Na-yeon again, as the girl had been insisting that they close the window incessantly. Y/N's eyes widened as she heard Na-yeon call her friend a welfie, earning a quick shove from him in response. It was then that Y/N realised a teacher had now joined them, remembering her name was Ms Park. She was asking what welfie meant, as clueless as all teachers usually were.
"It means a person on welfare" Su-hyeok mumbled, removing his backpack and placing it on the table.
"If you like names so much, Na-yeon, I'm sure I can think of a few for you" Y/N spat out, as her brother grabbed her arm to hold her back.
"Please, stay out of this" Ms Park told her, trying to diffuse the situation.
"Na-yeon, you were wrong. Don't ever say that again. And Gyeong-su, if you hit someone for saying that then you're the one who loses" Ms Park argued, making both Gyeong-su and Y/N scoff.
"I think there's only loser here" Y/N muttered, as she and Cheong-san pulled Gyeong-su away, not wanting to listen to whatever they teacher now had to say.
The others soon started trying to log on to a computer, hoping to find out what was going on outside, but Y/N had little hope. They could see from the window that infected students had left the school, and it was clear how quickly they could spread their disease. It was already too late. She was lost in her thoughts when the window suddenly smashed, causing them all to jump out of their skin.
"What the hell?" Cheong-san exclaimed, watching as the end of the hose continued swaying.
"Fuck. That scared me" Dae-su complained.
"Did someone not make it in?" Su-hyeok asked.
"No. Everyone's here" Cheong-san frowned, taking a step forward.
"Hey! Be careful!" Y/N insisted, going to follow him when she realised a hand was gripping onto her hip, keeping her in place.
"Uh, Su-heyok?" Y/N mumbled, gesturing to his hand, thinking he didn't realise what he was doing.
"You've got in danger enough today" Su-hyeok replied, keeping his hand in place.
Y/N shook her head at his words, cursing the way her cheeks began to blush again. It felt nice having his hands wrapped around her, not that she would admit it. A moment later, she felt another pair of eyes on her, finding it was Nam-ra staring openly at the pair. Nam-at averted her eyes to the floor when she found she had been caught, her lips pursed. She looked...upset?
A scream brought her out of her thoughts, as they watched a zombie appear at the window, it's foot hooked in one of the loops on the hose. Cheong-san was the first to race forward, grabbing a mop and trying to push their attacker away. But the zombie simply grabbed onto the mop, almost as if it was a game. Gyeong-su went to help his friend as they both tried to shove the zombie away, but it wasn't working. Y/N let out a gasp when the zombie began to claw at Gyeong-su's hand trying to bite him. She took a step forward, but Su-hyeok's hand hauled her back.
"Stay here" Su-hyeok insisted, rushing forward.
Cheong-san then attempted to hit the zombie with the mop, breaking it in half but barely affecting the zombie. He gripped tightly on the wooden mop, staring at the sharp end but for some reason he couldn't seem to hit the attacker. Su-hyeok didn't have the same problem, and quickly ripped the mop out of his hand, accidentally hitting Gyeong-su in the face as he did so. Y/N watched in a panic as Su-hyeok stabbed the zombie in the throat, causing it to still for a moment. They all flinched as the zombie continued growling and trying to crawl in shortly after. Worried about his safety, Y/N raced to his side despite her brother's protests.
"Together" Y/N exclaimed, placing her hands over his which were clutching onto the mop.
They then ripped the mop back out of the zombie, backing up a few steps before lunging forward, hitting the zombie in the forehead. They cheered as the zombie dropped to the ground below.
"We did it!" Su-hyeok grinned, slinging his arm over her shoulder to hold her close to his side.
Y/N beamed back at him until she heard an irritated cough from beside her, turning to see her brother glaring at the pair, his arms crossed. She quickly pulled herself away from Su-hyeok's side, hoping Cheong-san wouldn't think too much into it.
"Hey, Gyeong-su..." Na-yeon's sharp voice announced, causing them to whip around to face her.
"Your nose is bleeding" Na-yeon exclaimed
Shit, what now?
