This is my mandatory birthday prompt for #KiyoomiDay as promised to him. Happy birthday Atsumu's curly baby💚// #sakuatsu ft. osamu and hq fam

Crossroads Surprises//

Osamu sighed and looked at Kiyoomi dead in the eye, phone still slid between his shoulder and head

as all the people in the room hears Atsumu's wails and sentiments

His twin apparently has a massive adulting crisis, on their childhood home where he's camping his gifts for Kiyo

"SAMU! I SWEAR HE DOESN'T HAVE PLANS TO MARRY ME!"

Osamu sighed again before blowing his nth balloon for that day.

He's here blowing dozens and dozens of balloons and getting blinded by streamers and flowers just for the "day" his brother will say yes.

How ironic it is that it's Kiyoomi's birthday and yet it's Atsumu how will have the biggest surprise of his life

He's happy of course, only if he's not tasting the helium and inhaling pollens everywhere

And calming the nervous Kiyoomi, a.k.a soon to be brother-in-law.

Remind him again why he agreed to help?

Osamu went back to listening to his brother, rambling about Kiyoomi not planning to marry him although he swears he saw many signs of proposing these past few months.

"Calm yer tits, tsumu. It's his birthday, can't ya just set that aside and prepare for his day like a good ol' boyfriend does?" He needs to make tsumu think that nothing's happening today

But there is.

And Tsumu doesn't have any idea, of course

His twin screamed, horrified,"Yer right! I haven't shaved yet! And the cleaning supplies! The cleaning supplies!"

Osamu's brows shot up,"What about the cleaning supplies?" he asked confusedly

"It's Omi's gift, i bought him a robot vacuum with matching cleaning supplies that will last him till our hairs turn grey. Nothing will make Omi happy than a partner in cleaning and lots of sanitizers that can drown him"

Did Osamu mentioned that his twin is an idiot?

Yeah no

"That's it? Nothing else? And why can't ya be his cleaning partner?"

Atsumu laughed, "I am, I just don't think the vacuum will want ta suck cockroaches and spiders in our apartment. But no, I have a surprise and I can't waaaait for it"

Atsumu emphasized the "wait" as if he's planning on taking Kiyoomi and sending him to hell

Osamu shivered, he wonders if Suna is like that whenever their birthday comes.

Atsumu chirped remembering his surprise, as if it's lifting his spirits up, "Ciao, Samu. I'll prepare my surprise now~" the line went off

Osamu unsurely looked up to a pacing Kiyoomi. Yeah no, he ain't saving this guy fror his twin.

He has a no return, no exchange policy for Tsumu. He's all for Sakusa to handle

"Hey Kiyo, are ya sure ya want marry my twin? Does he even brush his teeth everyday?"

Kiyoomi stopped pacing and looked at him seriously, "Yeah, if he doesn't then I'll make him. Seriously though, the only birthday gift k want is him being completely mine. By the eyes of the law, by the eyes of above"

Osamu smiled fondly, silently thanking this guy who's about to love his brother for the rest of their lives.

**************
Atsumu grinned, he had always believed that if the opportunities won't open their door then you should climb their window

And that's what he's doing now.

He doesn't have anything that's extravagant, the vacuum and the cleaning supplies were scheduled to be delivered after he's done with his surprise

His surprised isn't even prepared, he just thought of it when he saw a pamphlet and wailing to Osamu about "it" a few hours ago

His Twin sure is busy today, he wonders what he is up to

Oh well, He'll just give him a ring later

After he give Kiyoomi his ring

Heh, prepare that window, Omi. Atsumu can't wait for the door to open

He rang the doorbell of their apartment, the moment the door opened he kneeled and confessed, hard

"OMI, THE LOVE OF MY LIFE. I CAN'T SIT AND WAIT ANYMORE SO I'LL BE THE ONE TO ASK YA. I AM GIVING MY HEART, SOUL, PROPERTIES AND EVEN SAMU'S PROPERTIES TO YA INCLUDING ONIGIRI MIYA SO PLEASE-" Atsumu breathed heavily

"Please marry me, Omi"

There he said it

"Amen" was that Ushijima's voice?

Atsumu looked up and saw Kiyoomi gaping with their friends in the background

Ushijima holding his hands like he's praying, Aran and Meian who's hands are froze while holding a streamer saying "Will you marry me, Atsu?" And his twin who looks like he's in Kidzoonia with the balloons swarming him

His gaze went back to Kiyoomi, then to the streamer

To Kiyoomi

Then at the streamer again

Holy shit

Kiyoomi laughed, his hands covering his face

He laughed and- wait is that tears?!

Atsumu panicked, "OMI! M'SORRY I RUINED YER SURPRISE I'M AN IDIOT OH GOD SHOULD WE RETAKE IT? I CAN PRETEND THAT THIS DIDN'T HAPPENED. DON'T CRY, OMI! M'SORRY I-"

Kiyoomi laughed and pulled the rambling Atsumu, wrapping his arms in the blonde's waist and claiming his lips in a kiss

Sweet and soft but also fiery, like he's owning Atsumu, body and soul

And Atsumu surrenders because who is he to stop this man?

This very gorgeous man who wanted to marry him the same way he does

Kiyoomi pulled away, a bit breathless but he laughed. "Can't always surprise you because you always got me first, babe"

Atsumu reddened, he remembered that he "ruined" Omi's plans

He fidgeted his fingers and was about to say sorry again when...

"Put it on me"

Atsumu looked up, "What?" he whispered

"Miya Atsumu, my number 1 setter. Number 1 boyfriend and soon to be husband, put the ring on me because i'm saying yes. In turn, you should say y-yes to me too" Kiyoomi's voice cracked

"I've been waiting to pop the question for a year now, but I figured you'd scramble something again for my birthday and i- i don't want anything else but spending an eternity with you.

I can now share you my towel, my mug, my blanket sometimes. I'll even help you bully Osamu so Miya Atsumu, without yours and Osamu's property but with your heart and soul."

Kiyoomi smiled, "Will you marry me?"

Atsumu laugh, while crying but even so he sang shakily

"If ya want it then you should put a ring on it~"

All their friends laughed while sniffling too.

It's classic Atsumu after all

And as a sign, both of them held each other's hands

Slipping their respective engagement rings

Because they both proposed

And to make it clear

Kiyoomi has plans to marry him

Before the clock hits 12AM, he pressed his forehead into Kiyoomi's and sniffled

"Happy birthday, Omi-omi. I love ya"

[FIN]

HAPPY BIRTHDAY OMI-OMI!💚💜
