Kageyama hates it. He hates Yamaguchi's new volleyball shoes. Kageyama remembers that Yamaguchi invited him to go the mall to help him buy some new shoes, but he declined the offer because he had early practice with Hinata the next day. But now he deeply regrets it. Maybe if he went with Yamaguchi that damn shoes wouldn't be there. That thing is taking his boyfriend away from him. OR Kageyama realizes(with some help) that he spends to much time with Hinata and this is making Yamaguchi sad.
