(Name) is Ukai Keishin's younger sister, the coach of Karasuno's Boys' Volleyball Team. Just like her brother and the Karasuno boys, (name) eats, breathers and lives off the art of volleyball. After returning from Russia, where she spent some time studying aboard, (name) is asked to be the assistant coach for the Boys' Volleyball Team, which is how she meets Tsukishima Kei, the most irritating male on earth who never fails to make her life miserable. Everything about this guy makes (name) hate him, especially his mean and narcissistic personality, which ticks her off the most. At the same time, Tsukishima isn't a huge fan of (name) either. They hate each other so much that being in the same room together could set off WW3. (Name) is certain that never in a million years will she ever like Tsukishima, or so she thinks. What (name) did not expect, of course, was to fall in love with him of all people, especially with him being her first love. Read as (name) helps the boys' team soar to greater heights and meet new interesting people long the way while she figures out her feelings for Tsukishima Kei. Maybe, just maybe, he might feel the same way, too. (Now available in Portuguese!)

Oikawa is an amazing player with incredibly good looks, so it's no wonder he has high self-esteem. He's confident enough to make a bet - he has to make a girl picked by Hanamaki fall in love with him in two months time. But what if this girl turns out to be you?

What will happen when [Name] finally confesses to Kuroo? And gets... Rejected? Will the two endure the test of their friendship and come back to how it was before?

"Volleyball is the most important to me", Oikawa said while rejecting you. He always considered having a girlfriend an obstacle in improving. So why did you see him kissing another girl?

Being able to see you everyday bought something new into Tsukishima's life. Whether that was just another annoying person to disrupt him, someone to calm him down or just another face he'd have to see everyday, he wasn't sure. But that was at first. What he did realise now was that he wasn't going to let the mark you made on his heart fade. He would make you stay even if it meant him showing his vulnerability. Even if he had to show you a new side. A New Moon

(Y/n) (l/n) was the prettiest girl Oikawa had ever seen. However there was one thing that made her different from the rest. She regected him. Never before had he been regected by a girl, he decides to take this opportunity by the hand and become friends with her. Although his intentions were pure he couldn't help but fall for her. What will the poor brunette have to go through to get the girl of his dreams? Friends? Foes? Fights? Oikawa : AUTHOR-CHAN! STOP MAKING EVERYTHING SERIOUS! Author : Why? This is good stuff! Oikawa : WHO AM I FIGHTING!? Author : There's a question mark. You might not have to. Oikawa : But- Iwaizumi : SHUT IT TRASHIKAWA OR YOU'LL HAVE TO FIGHT ME!! NOW LEAVE AUTHOR-CHAN ALONE! Author : Oo that's good! Best friends fighting! Oikawa : I HAVE TO FIGHT IWA-CHAN!! I'M GUNNA DIE!! Author : IF YOU DON'T SHUT UP I'LL MAKE YOU FIGHT HIM NOW! Iwaizumi : With pleasure. *cracking knuckles* Oikawa : NO!! DISCLAIM!! I DON'T OWN HAIKYUU!!!

What if one day you received a letter from your future self? The letter revealed all of the regrets you are going to make in your third year of school...and how to stop them from happening. There is one goal through all of it, don't loose Bokuto Koutarou. [Inspired by the manga/anime "Orange".]

We'd never really talked before. In fact, I'd always made it a point to avoid him. But Fate had another plan in store. Now here we are and my life is relying on the one person I've tried so hard to stay away from. But hey, at least he'll never know it's me, so I can be any way I want, right? I can be someone confident and strong and I won't feel flustered at all. At least, that's what I hope.

[Iwaizumi Hajime X Fem!Reader] "Iwa-chan has never dated before and it's time he finally got himself a girlfriend. So, I want to help you get the man of your dreams!" In which, Oikawa tries to be cupid and help [F/N] confess her feelings to Iwaizumi.
