Standing in the Winner's Court - Oikawa x Reader [DELAYED]

Idk. Cringy title, I know (sorry).
You have played volleyball all your life. In fact, volleyball IS your life. Good thing you're a pro at it. You were the captain of your team at your old school and you have been selected to join the newly co-ed team at Karasuno High School! Unfortunately, you're the only girl there for the time being. However, fitting in shouldn't be a problem, so you think everything will be normal there. But one of the rival schools, Aoba Johsai, has a popular star player- Toru Oikawa. He's extremely talented, probably as talented as you are. And the tournament is coming up. It could be Karasuno's chance to make it into Nationals! But when your school decides to host a practice match against Aoba Johsai, things could get a little bit dicey.
