You've talked before, and you often talk to him. You started to like him, but then you found out.. He killed your roommate, co-worker, and landlord, although you don't know when he did or how. Your dating him, but you feel the need to kill him.. but you still love him

You were leaving your shift at the diner you work at, when you saw Peter, holding a rose for you, waiting

"Darling~! Come on~! I have a date planned~"
