you are the lonely girl in the highschool, and this highschool is a mixed school, between vampires and humans. vampires rule here and humans are only servants of their blood. and you the only one who always holds the principle of not being a slave to a vampire.

you sitting on ur chair and the teacher told u to deliver documents to the room, you dont know if that was vampires room. you arrive at the room, you open the door and how damn u shocked. all the vampires currently biting human neck.
