Amongst the sea of cheers from Oikawa's fangirls and earger supporters to Aoba Johsai's highschool volleyball club, Oikawa's smirk and attention was mostly focused on you; his current partner.
You were a close friend of Iwaizumi (Iwaizumi saw you more as a sister than a friend), who ended up being a close friend of Oikawa too. The team appreciated your constant support. You were absolutely sweet, so kind and sometimes a bit snarky when someone gets on your bad side. You even pointed out Oikawa's pimple one time so nicely—he couldn't even get mad and just smiled back with the painful look on his face.
And maybe, even if that wasn't Oikawa's type of girl...he fell for you slowly and surely. Oikawa openly flirted with you, he would casually wrap his arm around your shoulder when he saw you walking down the same hallway, with the certainty the you seemed okay with him—he asked you out. You agreed.
A few dates happened, and he asked you to be his girlfriend properly. You said yes, happily. When he informed Iwaizumi and his team about it the next day—oh damn. Iwaizumi immediately grabbed his collar and threatened to give Oikawa daily volleyball service aces, but it'd hit Oikawa's head instead of the other side of the court if Oikawa ever hurt you. Oikawa's tears were frightened but certain he won't ever hurt you as he nodded frantically towards Iwaizumi.
So this leads to now, you and Oikawa had been dating for the past month. You were never bothered by his fangirls and even joined them cheering him on sometimes. Oikawa minimized interacting too flirty wuth those fangirls, he was only polite when they wanted photos or have something to give him.
It was already known you're Oikawa's girlfriend, you weren't just a normal student anyway. You were a pretty well known social media influencer. Oikawa being in your socials only added to the popularity, not that it mattered.
Right after the match, Oikawa was with his teammates as they thanked the crowd for cheering. As he walked with Iwaizumi some fangirls immediately rushed over to him and congratulated him. You were currently buying drinks with Kunimi and Kindaichi before a nearby News reporter approached you three—seeing the two boys were wearing their Seijoh volleyball jackets and you wore one of Oikawa's jerseys.
The reporter asked about how the play was to Kunimi and Kindaichi which Kindaichi nervously answered some short responses and 'It was fine' for the nonchalant Kunimi. The news reporter smiled and noticed you were wearing Oikawa's jersey, and realized you were the girlfriend.
Very predictably the reporter guided her mic towards you,
"How does it feel being Oikawa's girlfriend and always see him surrounded by flocks of other women who want him?"
The reporter asked with a small smile and expectanly wanted you to answer—obviously wanting something juicy for TV. Kunimi's head fully popped up from his jacket and frowned, so did Kindaichi seeing how dirty the scene was.
