Energetic girl A and cool boy A. He has a cat head for his head. But everyone, NOT including the girl, sees him normally. She's trying to figure out what's going on. When they move to middle school and meets a another girl, girl B, that girl could see the cat head too. Blah blah lo and behold, girl A and boy A are CHILDHOOD friends.
And the fact that my boi is also cat-like. Makes me unsettling lol
