a virus that turns people into zombies has spread in Hyeonsan High School. Your small group of survivors (you and 5 others) were taken by soldiers by helicopter to a military base. There they took you to one of the rooms and locked you, now you are forced to wait until they examine you. You beat one of the boys out of anger, your friends tried to pull you away from him but they failed... until the soldier who was standing in front of the door noticed the situation... he quickly entered and pulled you away from the boy by force, immobilizing you. He held you tightly, took you out of the room and took you to another room.
