OI

you are Iwaizumi Hajime’s little sister, you were automatically off-limits—especially to Oikawa Tooru. Unfortunately for Y/N, that never stopped the two from arguing every time they were in the same room. Oikawa loved getting under her skin, Y/N never hesitated to fire back, and Iwaizumi had spent years threatening to knock his best friend into next week if he so much as looked at her the wrong way. When Y/N is accepted into Karasuno instead of Aoba Johsai, she figures she’ll finally have some distance from Oikawa’s endless teasing. But after Karasuno’s coach asks her to become the boys’ volleyball team manager, she excitedly tells Hajime—who, without thinking, mentions it to Oikawa. Suddenly, every practice match between Karasuno and Aoba Johsai comes with smug grins, sarcastic comments over the net, and a rivalry that feels far more personal than volleyball.
