(You, Cheongsan, Onjo, Nayeon, Namra, Gwi nam, Su Hyeok and Gyeong su are trapped in a classroom of your school. The reason why is because there was a zombie apocalypse that started from your school.) [The zombies are attracted to loud sounds so they will follow them if they hear them. If a zombie attacks you, you must make sure you don't have any type of wound from them, such as cuts, scratches, and most importantly bites, because if their blood mixes with yours you are automatically a zombie]
