Work Text:

Kiyoomi always got told that he wasn’t a good omega. He was too bossy, too tall, too harsh. Many people told him no alpha would want him. Not that he particularly cared about anyone's second gender, but ouch, it hurt to hear especially from some of his closest family members.

Motoya always tried his best to defend him and steer conversations away from the topic, but as a beta, he was often pushed aside. This caused more issues since Kiyoomi would not allow anyone, family or not, to disrespect his cousin.

Kiyoomi had never been interested in anyone until he saw him. A spiker form Inarizaki. He watched him play, watched him bicker with a blonde who he learned was his twin, the twin he had met during training camp. The blonde was loud and clearly passionate about volleyball.

He was curious why the other wasn’t here with his twin. He had seen them play, and he was impressed. So, he asked. It was the first time he actually talked with the setter. The blonde had been defensive and dismissive but bothered by the lack of his twin by his side. Kiyoomi never asked again.

Following their first discussion, the two began a shaky bond. He discovered that both twins were alphas, that Atsumu was the older one (or so he claims), and he learned about a third-year boy they'd known for a long time, a third brother of sorts, a captain who encourages and keeps them in check, and a libero who enjoyed mocking them. He learns of a green-eyed boy who seems alike to himself.

But, most important of all, he learns about Osamu. Always calling Atsumu out when he takes his clothes and battles him over the last pudding. Who enjoys cooking as much as Atsumu enjoys volleyball. That's when he understands why the other isn't present. Atsumu is aware of this as well, reflected by the expression on his face, which is reluctant to admit or accept the truth.

By the end of the training camp, the setter and the spiker have become friends. When Kiyoomi gets home he learns that Motoya had shared his number with the blonde alpha. Kiyoomi is dreading the years to come. He wouldn’t have it any other way.

In a blink, Kiyoomi finds himself settling in his new dorm room. He is apprehensive about meeting his new roommate. Would they be a rowdy alpha expecting Kiyoomi to do as he says? An omega that would avoid Kiyoomi? Would they be messy? Loud? What if-

His rapidly derailing thoughts are interrupted by the door opening and the mix of lemon and honey hits his nose. In walks an alpha he never thought to see again. Roots are showing between gray hair, which is now slightly longer since he last saw the other at nationals.

“Neve’ thought I’d see ya here, thought ya would go pro right of high school,” Osamu says in the form of a greeting.

“I could say the same,” Kiyoomi responds, “Thought you would have gone pro along with your brother,” Kiyoomi has known since his second year that would never happen, at least not in this lifetime.

Osamu’s expression becomes guarded, “Maybe I just wanted something else for myself,” defensive, like he’s had to justify his decision many times.

“Well, maybe I wanted a backup plan,” Kiyoomi retorts back, watching as Osamu’s shoulders relax minutely.
Osamu gives a noncommittal hum changing the topic, “Have ya picked a room? Ya can have the first pick,” Osamu states bringing some boxes he had left by the entrance.

“Thanks,” Kiyoomi deadpans, already believing the offer was made for his secondary gender, “I already chose a room, I wasn’t letting the other person pick first.” Turning on his heels, the raven-haired boy swears he hears the other chuckle.

In the following days, the roommates get to know each other. Their quirks and what ticks the other off. Oddly enough, they complemented each other. Kiyoomi always found a clean kitchen (sink and all), along with a pristine bathroom. The first time he had walked into the newly cleaned bathroom he had inspected it, pleasantly surprised by the deep clean he found was done once a week. Kiyoomi cleaned the shared space. A burner always wafting a complementary smell to their mixing scents.

Kiyoomi was happy the alpha always maintained their space clean, only ever seeing a slight mess when the door to the other’s room was left open. He didn’t have to remind the other to pick up his stuff, to keep the noise down, to respect him. Osamu did all that and more by his own will. The curly-head felt that interest he had felt those few years ago start to resurface.

As the years went on, their friendship grew, along with the omega’s feelings. Every moment spent with the alpha, whether it be studying, hanging out, or even comforting the other when classes got too much, made Kiyoomi’s heartache.

Kiyoomi called one of his best friends, thanks to Osamu for introducing them. He paced his room waiting for the other to pick up, hoping he wasn’t in practice. When the call connected, he wasted no time.

“I don’t know what to do,” Kiyoomi confessed, “And if you don't help me, I’m kidnapping you and withholding all the jelly sticks.” He heard a startled laugh from the other end.

“Hello to you too, Yoomi,” Rintarou’s amused tone made him scowl, “No need to threaten my jelly sticks, what do you need.” His tone turned serious, knowing Kiyoomi didn’t call unless he was desperate.

“I’m in love with Osamu,” he whispers, this being the first time he admits it out loud.

Silence meets him at his confession. Panic starts coursing through his body. Oh god, he messed up. Why did he think it was a good idea to confess such a thing to one of Osamu’s oldest friends?

“You what!” The beta screeches, unusually loud, “About time!” Wait what.

“The hell you mean ‘about time’,” Kiyoomi’s tone is exasperated as he questions him.

“Yoomi, I tell you this with all the love I have for you.”

“Not very much then,” Kiyoomi interrupts.

“Shut up, and listen to me you pinning idiot,” Rintarou close to yells at him. At Kiyoomi’s silence, he continues, “In the year that I’ve known you I could tell you at least liked the guy,” Kiyoomi catches Rintarou whisper something along the lines of ‘Thank god it's this one and not the blonde’.

“We were just waiting for you to notice.” We?

“Who’s we, Ri’,” Kiyoomi can only hope it’s not Atsumu, “Motoya, who else,” is the snarky response. Thank god.

“Yea whatever you witch,” RIntarou grumbles ‘I’m not a witch, you’re just obvious’, which Kiyoomi completely ignores as he keeps talking, “What do I do.”

“You court him,” he says as it was obvious. And it was, only if Kiyoomi hadn’t been doing that for the past four months, “What do you think I’ve been doing these past four months,” Kiyoomi deadpans, “I may have never admitted I love him, but I’ve been trying.” He is near hysterics and the beta has the gal to laugh at him. “Neither of the twins has ever been good at getting hints like this, especially Osamu,” Yeah, Kiyoomi can tell, since Rintarou is also trying with Atsumu.

“How’s it going with yours?” Kiyoomi can’t help but ask, “We aren’t here to talk about my problems,” the green-eyed man quickly shuts him down. Kiyoomi smirks as the other keeps talking as he isn’t blushing on the other side of the phone, “Continue with the courting and you hit him for being an idiot once he notices,” that makes Kiyoomi chuckle.

“Alright, thank you Ri’” Kiyoomi thanked softly.

“Of course,” Rintarou’s tone is just as light, before turning teasing, “I’ll be your maid of honor at the wedding.” Kiyoomi laughs, “Motoya is going to fight you for that title,” he jokes. “I can take him,” Rintarou says confidently. With a last goodbye, the line goes silent.

Kiyoomi takes a deep, steadying breath. Okay so, change in plans. No more subtle gifts, well maybe he can still get the other some stuff anyway…

Kiyoomi gets bolder with his gifts. The gifts he gave the other with the excuse of ‘They reminded me of you’? He still gave him those, and now he just added something else along with them. The new knife set he gave him? Came with freshly baked pastries Kiyoomi made himself. He doesn’t just bake for anyone, Osamu knows this.

That new hoodie Osamu had been eying every time they walked past it? He got it for him, scenting it heavily with his subtle flowery yet slightly acidic scent. A scent he knows mixes perfectly with Osamu’s own after all their cuddle sessions on their couch.

Maybe the scenting is also his way to stake his claim on the alpha. Stupid alpha, always surrounded by other omegas rubbing themselves on him. Kiyoomi has to suppress his growls whenever he catches a whiff of their scent on him.

Just like right now, they are sitting at one of the tables in the cafeteria, surrounded by their friends and this extra. Kiyoomi admits the omega is a pretty little thing, but her scent is just too sweet, artificial if you will. Hugging and pressing her chest against Osamu’s arm, who hadn’t been able to eat since the girl joined them How dare she.

A kick to his shin stops the light growls coming from him. Kenma’s, his attacker, attention has left his game and is now on him. Akaashi sent him a pointed look, and Bokuto, who was visiting him for the weekend, sent his own worried look towards him. Enough is enough.

“Hey, Osamu?” Kiyoomi starts without looking at him, instantly gathering the alpha’s attention, smelling that sickly sweet scent that turns sour, “Will you help me build my nest?” Kiyoomi turns to Osamu now, looking at him through his lashes. Osamu choked as did the rest of the table, except Akaashi, who has a small grin decorating his face.

“‘Mi…,” Osamu gulps, “Are you sure?” the now natural brunette stutters slightly as he asks. The girl omega had excused herself at some point briskly walking away. Kiyoomi grabs Osamu’s wrist, bringing it up to his scent gland, “I’m sure,” he confirms, rubbing the alpha's wrist against his neck, scenting him, marking him.

Osamu’s breath stutters, eyes locked where his wrist meets Kiyoomi’s neck, “Okay,” he whispers. Kiyoomi smiles internally, victorious. Soon after he drags Osamu back to their dorm, the other following behind him like a puppy.

Once inside their dorm, Kiyoomi makes quick work of standing before Osamu’s door, expecting. Osamu stares at him dumbfounded for a few minutes. Kiyoomi stays, patient. Shaking his head abruptly, he opens the door and holds it for Kiyoomi to walk in first.

Inside the room, Kiyoomi waits for no invitation to search Osamu’s drawers and closet. Osamu stands by his door, blushing and letting Kiyoomi search his room. Kiyoomi takes Osamu’s favorite hoodie for his closet, recently washed, but that simply won't do.

“Scent this,” Kiyoomi throws the piece of clothing to Osamu as he heads for the drawer, “And this,” he throws another piece of clothing to him, this one an old Inarizaki jersey that somehow still fits Osamu. As he turns to leave, he grabs Osamu’s sweatpants he has been using to sleep.

Grabbing Osamu’s hand as he leaves the room, he drags him to his own room. Pushing the door open he makes Osamu sit at his desk chair as he gathers his other stuff for his nest. Quickly he fishes out the different bags holding his friends' scented items. Placing the bags on his bed, he pushed aside all his pillows and blankets, before carefully arranging them in a neat circle.

Osamu watched as Kiyoomi picked the first bad, Motoya’s, and arranged the items neatly, every position carefully considered. Shirts, a blanket, and a weasel plush that looked eerily similar to his cousin close to the top of the nest. Next was Akaashi and Bokuto from them he got three hoodies one with each of their scents and the other with their mixed scent. Kenma sent him a small kitty plush. All these items he placed by the end of his nest. Next, he opens Rintarou’s and Atsumu’s bags. Placing the items intertwined in the middle of his nest.

Standing from the bed, he stood examining the bed. Making quick and slight changes, he nods to himself, running out of the room and coming back with the blanket he and Osamu share when they cuddle on the couch.

“Sit in the nest,” Kiyoomi demands of Osamu.

Osamu freezes on his spot. Eyes darting from Kiyoomi’s nest to him, “You…” Osamu hesitates, “You want me to get in your nest?” Kiyoomi’s omega whines at the alpha’s hesitation.

“You don’t want to?” Kiyoomi asks softly, sadness creeping into his tone.

Osamu’s eyes widen, rushing to reassure the omega, “No! That’s not it,” he tries to say gently, “Jus’ wan’ ta be sure this is what ya want.”

Kiyoomi can’t help but glare at the idiot alpha, “If I didn’t want you,” his pause is deliberate, “You wouldn’t even see what my room looks like.”

Osamu searches Kiyoomi’s eyes, beaming suddenly. He turns to Kiyoomi’s nest, gently entering the omega’s space. He sits; legs crossed careful not to break this precious space. Kiyoomi walks towards him as the brunette looks at him.

With a hand on Osamu’s chest, he pushes him down. Happy with Osamu’s place in his nest, he moves to pick up the items he carefully chose from Osamu’s room. Then, right in front of Osamu’s watchful gaze, he stripped down to his underwear. Dressing in Osamu’s sleeping sweatpants, followed by his old jersey, he grabs their blanket, stalking to his bed. He joins Osamu in the center of his nest, purring loudly. His nest was finally complete. He lays next to Osamu, throwing their blanket over both of them.

Osamu quickly wraps Kiyoomi in his arms. Picking one of the raven-head legs and throwing it over his thigh. Holding him tightly against his body. Kiyoomi’s purrs never let up on their intensity.

“I love you,” Kiyoomi finally confesses, looking up at Osamu.

Osamu tenses momentarily, looking down at him before relaxing and smiling softly, crooning, “Why ya never told me?” Kiyoomi huffs and purrs stopping, “You never noticed,” Osamu startles, “I’ve been courting you for almost six months now,” Osamu’s face makes Kiyoomi laugh.

“‘m sorry,” Osamu mumbles, hiding his face against Kiyoomi’s chest.

“It’s quite alright,” Kiyoomi consoles him, pulling lightly at his hair to get him out of hiding, “You’re mine now, right?” he asks.

Osamu smiles at him, capturing his lips in a soft, tender, and full-of-love kiss, “Of course I am,” Osamu kisses him one more time, “I love you,” he says lovingly, nuzzling Kiyoomi’s hair.

Kiyoomi’s purrs start once more, holding his alpha close to him. He lets his pheromones cover them, Osamu copying soon after, their scents mixing to perfection. Suddenly he lands a loud smack on Osamu.

“What was that for!” Osamu jumps, “That’s for not noticing,” Osamu blushes at the reminder, “Yea’, I deserved that.” Both men laugh, joyful and content, finally together.
