Shoujo manga, where the girl is but she is super strong. She's mistaken for a kid, but I think she's in highschool. Or college, I'm not really sure. She works in a pastry shop with two other guys- a black haired dude and a light haired dude. The black haired dude is her love interest. The light haired dud is super chill and super funny
