omi who never met atsumu in high school cuz he didn't play vb, but motoya did.
omi went through the stages of hearing about motoya's crush to when they flirted with each other to finally dating in their third year.
and like, you know when your friend (cousin in this case) is dating someone shitty, but they just ignore all advice?
'atsumu hasn't answered my texts.' 'i got into the dumbest fight with atsumu.' 'why does atsumu keep talking to those girls on insta?!'
apparently things are /good/ when they're together, but the distance means atsumu is acting like a fool.
and omi hears all of it, he's like a fuckin diary of motoya's relationship with his terrible boyfriend.
but motoya wont dump him cuz atsumu is hot and the sex is great. so omi suffers through his third year.
like, is he this annoying about his crush on ushijima?god he hopes not…
and like… ok…. omi has seen atsumu in person once.
the nationals cuz omi had to go support his cousin ofc. he looks and sounds as obnoxious as omi assumed.
omi doesn't get it, but whatever. he passes on eating dinner with a bunch of jocks and that's pretty much the last time he sees atsumu.
he's a year away from graduating and keiji invites him to osaka for a lil three day vacation away from Academia.
bokuto got them both tickets to his msby game too, soooo. whatever, he'll take the break.
now, omi's barely heard about atsumu in recent years. he only follows motoya, bokuto, and ushi (out of habit) when comes to vb.
he knows bo has a roommate. he doesn't care enough to ask about them since he'll only be here for 3 days.
so ya know, he's only a little shocked when he spots atsumu lazing about on the couch when bokuto picked them from the station.
and he's gotten…….. hotter……… jesus christ those thick thighs. omi's eyes are immediately going UP and AWAY from atsumu manspreading.
"Sakusa? Komori's cousin, huh?"
there's something about the way atsumu's gaze lingers on omi. the faint smirk on the corner of his lips.
"Yes, I hope I'm not intruding…"
omi says as bokuto and keiji have disappeared into bo's room to finish what they started at the station.
"It's whatever babe, make yerself at home… I was gonna head out ta give 'em some privacy…"
atsumu's smirk only grows wider, "Akaashi-kun is a screamer."
"You think I don't know that by now?"
atsumu laughs and its kind of a beautiful noise- wait. no.
so like, motoya and atsumu broke up after two years and omi was just thrilled that toya realized he deserved better.
but…. ok. omi could quietly admit there was an attractive, charming air around atsumu.
"Well, how 'bout I make myself decent and show ya around?"
a rejection is on the tip of omi's tongue, but god knows he's left their apartment plenty of times when bokuto came over and.. ergh…
omi just gives a very non-committal shrug.
not a yes or no. but. if he happens to follow atsumu out of the door, it's not a crime.
the next three days are a nice reprieve from school shit and all those stressors. and atsumu is… annoying, but. hot. witty. a great cook.
he follows omi on his socials when he leaves for tokyo and thats how they wind up DMing back and forth.
it's a lot easier to reject atsumu over text when he gets too flirty, but not when atsumu video calls him and looks so fucking gorgeous.
"I have a game in Tokyo next week~"
"I wanna see ya, been thinkin' about ya, Kiyoomi."
all the things motoya complained about spring to mind…. but if they hook up once, it won't be the worst thing.
keiji is sippin' his tea and tilts his head in such a cute way when he sees omi greet atsumu at the door.
it takes a total of ten seconds for atsumu to get his lips on omi and their clothes hitting the floor.
'just once' is a fucking lie. ain't no way atsumu was gonna be satisfied with fucking him only /once/.
(his words when he was holding omi by the hips and grinding into him)
omi had to agree with that. my god atsumu was amazing in bed.
but also……… outside of it.
there were the good morning/night texts. atsumu sending him flowers. atsumu wanting so much of omi's attention. wanting to know about his day. listening to omi vent about his dumbass group project mates.
omi's schedule was a little more flexible in that he could come down to osaka and spend quality time with his boyfriend.
and get dicked down as a distraction from homework but anyway.
he does tell motoya…… sometime…….. like a month after they make it exclusive.
motoya is in disbelief 💔 tells omi good luck with that one, atsumu is the most selfish person he knew!!
he absolutely will not tell his cousin that atsumu's been the best boyfriend he's ever had.
and how he plans on moving to osaka after graduation just to be closer…
//tsumu being bad at relationships until he sees omi and wow NOW he's putting effort.
