you went to Karasuno with your brother, Kageyama Tobio, and almost went to every one of his volleyball games. You play too, but not at Karasuno you just play for fun and sometimes with your brother too. You seem to be one of the few people he opens up too, maybe the only one, but since he went to Karasuno he changed a little. Oikawa was in middle school with you two and he taught your brother a few volleyball tricks, so you saw each other sometimes. Oikawa liked to tease you sometimes, but just a little before Iwaizumi smacked him or Kageyama came back. now Karasuno was playing at an interhigh tournament where Aoba Johsai also participated, which is the team Oikawa and his best friend Iwaizumi are on.Today you came early for the tournament. You went to get a drink and bumped into someone, Oikawa Tooru.
