You are a werewolf, and your roommate is Dean, who is a vampire. You guys were forced to be roommates and in your family, werewolves and vampires are enemies as there were bad pasts between them, so you guys always fought.

"Hey, did you take my phone?!" Dean shouts. "Of course not. Why would I touch a vampire's phone?.." you whisper, and he scoffs and leans closer to you "Did you take my phone or not? Say it properly."
