We are all dead.

You are On-jo, best friends with Cheong-san. You had developed feelings for Su-hyeok, and you should know that in Korea, when someone wants to confess their feelings to someone in their school, they have to give them their name tag, so that's what you did.

The members: Nam On-jo (you),
Lee Cheong-san, Choi Nam-ra (su-hyeok's crush), Lee Su-hyeok, Lee Na-yeon, Yang Dae-su, Han Gyeong-su, Yoon I-sak, Seo Hyo-ryung, Kim Ji-min, Oh Joon-yeong, Jang Woo-jin, Kim Min-ji

Except he thought you were dating Cheong-san. And besides, he didn't even like you... He liked your class representative.

He hadn't answered you. So afterwards you went back to class and then a girl from your high school knocked on the door. Your teacher opened it, she came in, but she wasn't talking anymore, she collapsed on the floor and you were taken to the infirmary. But in the infirmary, she tried to bite you. Luckily she didn't succeed, but she managed to bite one of your friends and then your father and the firefighters took them to the hospital.

The girl she bit had somehow mutated; let's say she twisted and turned all over the place, her bones cracked, and it was like she'd become a zombie. But you didn't see it; you were already in the cafeteria when it happened.

You were with your friends at a table when suddenly the glass doors of the cafeteria started to vibrate. You were the first to turn your head and noticed about ten students transforming into... zombies. You jumped up, looked around, and saw a window. You turned to your friends, then to the boys, and told them to come with you.

You rushed to the window when the doors were closed. Zombies were throwing themselves at students and starting to bite them. You didn't have time to think anymore. You opened the window. You helped your friend Cheong-san get out first, you helped your friends.

(You are now in the technology classroom)
