#sunaosa | cocky and flirty suna, oblivious osamu (lol)

"Not there," Suna shakes his head. "Kinda wonky."

"Huh, here then?" Osamu tilted the sign in his hand. Suna hums behind him. They were trying to put up a class cafe sign for the school's cultural festival.

Osamu was in charge of hanging it, so Suna decides to help.

Well, not really. All he wanted to do was to stare at Osamu’s ass as the boy hobbles around the entryway of their class.

"Here?" He repeats the question, glancing back at Suna.

"Huh? Not really." Suna smirked, walking

up right behind his friend. He loops a finger in one of Osamu’s belt loops to tug him into the right position, pressing their bodies close.

"Riiight here." He murmurs. To his dismay and slight amusement, Osamu didnt even look affected. The boy just taped the sign and

sidestepped Suna to look at it.

"Hey, yer right. Nice placement, Rin. Now help me out with the menu." He pats Suna on his arm twice before walking back into the classroom.

Suna sighs. Osamu is either really dense or he's just pretending to not notice.

And Suna is unfortunately betting on the former, since he really genuinely thinks Osamu is too dense.

Perhaps Atsumu got all the perceptive genes, because Osamu wouldn't get some things if they weren't obvious snd spelled out in front of him.

"Rin!"

"Coming!" He hollers back.

Oh well, better luck next time, he cheers himself. See, because no matter how dense Osamu is, Suna can't find it in himself to feel annoyed.

In fact, he's annoyed at himself to find that trait on Osamu adorable. It makes him want to smother Osamu with kisses and praises.

Atsumu called him a simp, because of course the blond twin caught on his crush for his brother better than the intended party. Suna just rolls his eyes.

"Ya gotta up the ante. Samu doesnt know if ya straight up flirted with him or not. He's kinda stupid."

"Yeah," Suna had said

with a dreamy sigh, a fond smile on his face. "He kinda is."

"Ugh, gross."

So here he is now, getting his waist measured so that the girls could go buy the right sized butler uniform. He watches as a girl nervously approach Osamu, tape measure in her shaking hand.

"U-uh, Osamu-kun?"

She falters when Osamu looks at her. She was one of the quieter ones in class, the ones who get shy easily.

"Yeah?"

"M-measurements for-"

"The butler costume." Suna swoops in to the rescue. "You need measurements, right?"

"Yes!" She looked slightly more

comfortable with Suna present. Suna took the measuring tape from her hands.

"It's alright. I'll do it. What first?"

"The shoulders." She read off a list she was holding.

"Stand straight, pretty boy," Suna instructed. Osamu grumbled something, lips pursed slightly in a cute

pout. Suna resisted the urge to lean in and kiss him.

"What's that?" He asked after relaying the measurements to the girl. Chest next.

"I'm not pretty." Osamu mumbles, looking down as Suna circled the measuring tape around his chest.

"Look up," Suna instructed. Osamu did and Suna gives him credit for not flinching at how close their faces are. The middle blocker smirked.

"See, up close you look real pretty. 39.5 inches, by the way." he says without even breaking eye contact with Osamu.

"Um, next is waist."

"I'm not a girl," Osamu whines as Suna steps closer, holding the measuring tape taut behind Osamu’s back, slowly inching down to his waist.

"Who says you need to be a girl to be told you're pretty?" There was a mischievous twinkle in his eyes. He wrapped the tape around

Osamu’s waist and pulled it tight. "Would you look at that. 27 inches. Small and petite, my pretty."

"Too tight," Osamu huffs thumping Suna’s chest. He lets a relieved breath out when Suna loosens the tape. "Don't take that, that's too tight."

"28 inches," Suna amends. Osamu

pouts at him, and Suna laughs. He leans in to nuzzle at Osamu’s collar.

"Cute. Dont make that face to anyone else, yeah?"

The girl stuttered a 'hips', eyes glued to the two boys in front of her.

"Nobody teases me like you do, not even 'Tsumu, and he's the worse."

"So I'm

even worse than Atsumu? Cruel, Samu."

"No, ya aint." Osamu says softly, looking down as Suna slides the tape around his ass and to his front, their bowed heads touching and leaning against each other. "I like ya more that anyone else, really."

"Glad to know," Suna chuckles.

He turns his head to hand the girl the measuring tape. "37."

"Th-thank you Suna-kun, Osamu-kun."

She scampers off, face red. Osamu scratches his cheek, wonders if she was okay. Suna shrugs.

"C'mon. Lunch time. I'll buy you a pizza sandwich."

"Oh," Osamu’s eyes sparkled at

that. "Nice!" He follows Suna, unaware of the gleeful stares he's getting from their classmates.

A week passed and it was the school cultural festival. Osamu huffs as he roughly tucks in his shirt into his pants, huffing louder and untucks them again.

"Need help, Samu?" Suna asks, an amused smile on his face. Osamu pouts, nodded.

"The shirt's too starchy. I cant... its not comfy," he whines as Suna approaches him.

"Hmm, gonna have to unbutton these, kay?" He tugs on the pants. Osamu nods, letting Suna unbuttons them.

Suna sucks in a breath. He always imagines himself pulling down Osamu’s pants, but surely not like this.

"How are you 17 and you still dont know how to properly tuck in your shirt?"

"Too starchy!" Osamu defends himself. Suna chuckles, smoothes down the slightly crumpled shirt

onto his body, humming as his hands deliberately pats down his ass and thighs.

"You got a nice ass, Samu."

"Really? Atsumu says it looks big. Am I getting fat?"

"All in the right places, no worries," Suna says with a grin, buckling Osamu’s pants up again. He runs his fingers

down Osamu’s thighs teasingly. "Cute."

"You sure I don't look fat? Maybe I could do some more squats after this." Osamu mumbles, clearly bothered.

"I'll spot you. No worries." Suna grins. Osamu smiles at him, delighted.

"Cool! Now just the jacket... c'mon Rin, we can't take

too long. The girls are gonna complain."

Another missed shot. Suna sighs, but follows him back to class.

Their class was busy, the concept of a butler and maid cafe attracting crowds. Despite seeing his pretty classmates in maid dresses acting cute, Suna couldn't seem to stray

away from staring at Osamu. The way the pants hugs his legs, the way the jacket emphasizes his small waist, his easy smile and sleepy eyes.

"Ooh, look at Osamu-kun," he heard a group of girls whisper amongst each other.

"He looks so good!"

"He does! Oh my, Rintarou-kun also

looks good!"

Their hushed whispers had him thinking of something. He grins and sneakily drops a fork on the floor.

"Samu!" He calls. "Come here for a sec, will you?"

"Oh? Okay." Osamu predictably did not look where he was going and trips on the fork.

Immediately Suna catches him, an arm around his waist and pulls him tight.

Squeals and gleeful shouts. Suna smirks at the dazed Osamu.

"Careful, pretty. You almost fell."

"Oh..." Osamu slowly straightened up, didnt even push Suna’s hand off of him. "Thanks Rin."

"Anytime," Suna winks. Osamu laughs, patting his shoulder.

The group of girls left a huge tip as they left. Osamu brightens, their class goal has been reached.

Suna hums from afar. Perhaps next time. Next time, Osamu will definitely pick up on his crush.
