Gojo knew very well Maki only wore ponytails but he knew exactly why he put her hair in a bun. It was a habit. It was a dirty old habit that caused his hands to get to work before his mind had time to stop himself. It was a habit that he didn't know if he'd gotten rid of because it had been years since he'd last put someone's hair up. And it was years of putting up Getou's hair that had caused him to form this habit in the first place.
