#SakuAtsuFluffWeek2021 - Day 6 - Wedding @sktsfluffweek

Osamu gets the front seat as Kiyoomi and Atsumu debate over who gets to walk down the aisle.

--

“So who gets to walk down the aisle again?”

“Oh, I will.” / “Of course it’s me.”

Osamu’s eyebrows raise in intrigue as the engaged couple snap their heads towards each other, mouths agape. Kiyoomi furrows his eyebrows and purses his lips in thought. “It’s me… right?”

“Why is it you?” Atsumu asks, confusion contorting his face.

“Oh, god,” Osamu spits out a laugh, hands rifling through the day’s profits. “You idiots never talked about it. There’s literally one week left until the wedding rehearsal.”

Suna shakes his head as he helps Komori wipe the counter, their movements honed and refined out of habit. Onigiri Miya has been long empty for hours now except for its five late-night regulars crowding the counter and poring over the couple’s wedding plans.

“I thought it’s me, y’know, because you’re already taking my last name,” Atsumu offers, gesturing wildly to his fiance.

“I thought it was a given that it’s me, since /I’m/ the one taking your last name,” Kiyoomi rebuts and tilts his head.

Osamu wishes he didn’t see Kiyoomi pout and marvels at the difference between the stoic spiker who always beat their asses in high school to the pouting man currently insisting that he should be the one to walk down the aisle towards his idiot twin. “Isn’t that how weddings go?”

Atsumu looks back at his fiance half in awe and half in laughter. “Omi, love, we’re gay. Why are you thinking about straight wedding culture?” Atsumu is baffled now, the lines in his forehead deepening. Osamu snorts without taking his mind off of the bills in his hands.

“I thought it’d be me so I can show off my suit. And everything else,” Atsumu grins, waving a hand towards his thighs before smacking his own ass.

All four of his company groan collectively. “What?! I want everyone ta see what they’re missin’! That I’m Omi’s and only Omi’s!”

Osamu does not fail to see the blush bloom in Kiyoomi’s cheeks even as he scowls. He knows Tsumu sees it, anyway, if the telltale smirk on his twin’s face is any indication.

“Anyway, besides that…” The trail in Tsumu’s voice makes Osamu look up.

Now it is /Atsumu/ who is blushing, shoulders rounding in a show of timidity all too foreign for Atsumu’s famed shamelessness.

All three of them are staring at Atsumu now as he hung his head, fingers drawing endless circles on the counter.

“Ya already took my last name, so ya know… me walking down the aisle should be symbolic, like me provin’ to ya that I’m worthy enough for you to give up yer last name and take mine. Like, meetin’ ya halfway, or somethin’. I don’t know.”

Suna laughs and folds the rag neatly, setting it above the counter. Osamu is just dumbfounded. He looks back and forth between the couple and catches Kiyoomi rolling his eyes. It does nothing to conceal the blush dusting his cheeks and ears, though.

“That’s so cheesy, Atsumu.” Kiyoomi teases, but the smile on his lips says otherwise. “You know you don’t have to do that, right?”

Atsumu sits upright, resolve lining his body. “But isn’t that marriage, though? We both put in effort to make it work? Besides, I /want/ to!”

Kiyoomi’s eyes crinkle as he smiles softly, the ring glinting as Kiyoomi cradles Tsumu’s face and pulls him in for a kiss. He hears Suna and Komori groan in the background. He would’ve joined but he couldn’t stop himself from smiling. His twin’s happy. Why be a killjoy about it?

“Okay. If that’s what you want.” Atsumu pecks Kiyoomi’s lips and whispers a soft “I love you”. The grin in Tsumu’s face turns Osamu to mush.

Then Tsumu perks up, twisting towards him. “I have one more reason, though. I think it should be me so Samu can walk me to the altar.”

Osamu freezes, the bills now forgotten. He can count them later. “What?”

“Ya heard me. We’re breakin’ usual wedding traditions anyway, so why not?”

Osamu wants to cry. He jokes instead. “Pa’s gonna hate ya for that.”

“Nah, he won’t. Maybe at first. But I think he’ll get it.”

Tsumu looks at him, hopeful. “So? Will ya walk me down the aisle, Samu?”

He’s too overwhelmed, too happy. “Of course.” Atsumu grins and jumps over the counter, hugging Osamu. He can’t stop his tears anymore. And, if the wet patch on his t-shirt is a sign, neither can Tsumu.

“Anyway,” Tsumu says as he pulls away, eyes still red, “at least Suna can stop whinin’ now that he’s promoted to best man.”

“HELL YEAH! Best friend rights!” Suna shouts from behind the counter, waving the rag like a flag, while Osamu asks “Wait, I’m no longer best man?”

“Come on, Samu, you’re his best man since the fucking /womb/. Give me this one, babe,” Suna responds as he wraps his arms around Samu’s waist.

“I’m kinda bummed knowing that Kiyo will never ask me to walk him to the altar,” Komori comments, frowning. Kiyoomi only shrugs.

“You don’t know that,” Kiyoomi says casually. “HOLD UP, KIYOOMI. Are you saying there’s a chance?” Kiyoomi just shrugs again.

Komori swats a hand at Suna at Samu, bouncing at his feet. “Back off, you two. Kiyo’s walking. Kiyo’s walking so /I/ can walk him down the aisle.”

“Hey! You don’t get to decide!” The debate begins again, now with stupider and stupider arguments. Five voices scream over the quiet in Onigiri Miya, and Osamu wouldn’t trade it for anything else. His heart is so full, so happy.

God, that wedding is going to be a riot.
