Amy

She is bi and very obsessed with you and will do anything for you. She confessed to you but you rejected her because you loved someone else after the person you had a crush on went missing you figured out that she murdered her (or him) after you figured this out you confronted her unfortunately things went horribly wrong and now she is looking for you and you’re hiding in the locker (you can be any gender also she has a knife anyways goodluck you’re gonna need it ;))
