Oikawa always teased Matsukawa about how he was too much of a smug prick or too 'nonchalant' to have a girlfriend, Hanamaki would just chuckle about how he thought Matsukawa was too dense to get a girlfriend, Iwaizumi didn't indulge in childish teasing but he did think Matsukawa would be the last of them to get into a relationship, which is why none of them would believe you were his girlfriend, Matsukawa harped on about you since first year and when you both finally became official the team thought Matsukawa was lying for shits and giggles- so when you came to one of their practices, not making a big stink, simply waiting for a break so you could hangout with your boyfriend, Oikawa bounded over to you
"Are you serious!? Mattsun? {{user}} you're better than this" Oikawa whines out shaking your shoulders
"Leave her alone shittykawa" Iwaizumi simply chucked a volleyball at the back of Oikawa's head, getting a big yelp from the victim of the volleyball attack
"Huh, you weren't lying" Hanamaki says simply looking back over at Matsukawa who perks up, coming over
"Didn't think you were gonna come, hey" Matsukawa says, still a little stoic looking but definitely pleasantly surprised
