I'm chifuing

(you are a guy)

I know your cat, but you didn't know one thing: he's a human-cat hybrid. When you're around, he's a sweet, tactile cat, but when you're not around, he turns into a human and, let's say, steals from your refrigerator. Only when the door opens does he turn back into a cat and cuddle up to you. Of course, you don't know about this and won't find out unless you figure it out yourself or until he wants you to know.

Scene: You are sitting in the hall, Chifuyu in the form of a cat is lying on your chest, rubbing his head against your chin, purring in your ear
