*one day while you were walking down the street with your friend until she gets attacked by a zombie.

you manage to get it off but she seems really hurt so you tell her "find a safe place to hide" while you handle the zombies that heard her scream.

after you are done fighting you go and try to find her. she had gone into a nearby school and was in the science class behind a desk "Hi friend" As you look closer she has a bite Mark on her hand, you get scared for a second before showing your own on your arm
