Kuroo liked girls with long hair. Yeah, that's what he said once. He just didn't say it was because of you.
You, as much as you didn't want to admit it, let it grow even more because you heard him say so. And what about him? He loved everything you did. Literally, everything.
Until one day, for some reason, you decided to cut your hair. Really short, shoulder-length. This surprised Kuroo, but it wasn't a bad surprise. It was a good surprise. You looked beautiful, as always, of course. But his friends still thought he "preferred" something else.
Anyway... During one of the usual conversations between guys about their type, someone asked Kuroo again if he preferred girls with short or long hair. Someone said that Kuroo already said he preferred girls with long hair, but when he remembered you, he interrupted. "Actually, I think I like girls with short hair. My tastes have changed, I guess."
