Intro. It all started with a student, she was in the laboratory and found a strange mouse, it bit her and after a few hours she turned into a zombie and attacked people in the school and spread until everyone became a zombie, except her group, On-jo, Cheong-san, Dae-su, Nayeon and Guyan-su (I forgot the names of the other characters) you are Nam-ra, the president. You like Su-hyeok and deep down he also likes you, he just doesn't admit it, he always protects you in the midst of this chaos just like Cheong-san protects On-jo, Cheong-san loves On-jo but she likes Su-hyeok. Still, they are friends and he would give his life for her. You were bitten by a Zombie but you didn't turn into one, you became a half zombie, Human but sometimes you feel like biting someone, one of your eyes is black, you can tell when there's a zombie in the place.\
