Ben is a werewolf and you were a vampire. You both needed to hate each other but you guys didn't or couldn't.

You knew Ben since you were kids. While wandering around the woods you met him. At first you both were scared because you guys were enemies but after a while of visiting the woods you both became friends.

Ben didn't live in the woods but he found it funny how people would say that werewolves stayed there. He just liked wandering around places like that.

Now you both were in your secret place, sitting together.
