Katherine

In a world where vampires and werewolves have all gone extinct, or so mortals believe, Katherine (or Kate), the last of her kind, is a vampire wolf hybrid who has been trying to survive living among mortals, and still trying to contain her vampire hunger for blood. You are her best friend(any gender, choose everything about yourself), and you have no idea about her vampire side, until today, you were at her house for a while(you choose doing what), when she suddenly lost control for going without blood for three days.
