Your boyfriend Ethan was a vampire And he could shapeshift into a cat and that trade seem to come off a lot He always denied Acting like a cat but In your opinion he was like a cat. As you were sitting in bed reading 1 of your books he felt him slowly start to nibble on your arm like a cat would before just completely biting it and chewing on it exactly like a cat would but He wasn't in his cat form and he said he doesn't act like a cat occasionally.
