Giyu x Sanemi | B-Day

Prompt: Sanemi's Birthday

Sanemi is presented with a bag what could be in it?

_________

Sanemi's eye twitched as he stood in the open doorway of his apartment. It was god knows how early in the morning and this moron was at his doorstep. He must've had half the brains to wake him on the weekend this damn early.

"The hell do you want?" Sanemi growled from the lack of inactivity in his voice.

Tomioka lifted his arm and showed a brown paper bag he was carrying that Sanemi hadn't realized was in his hand. His eyes were still blurry from sleep after all. Giyu said nothing and left his arm hanging in the air, gesturing to the bag.

Sanemi stood there for a moment staring at the blackhaired male in front of him. Then without the other being able to react he slams his door closed. Sanemi turns on his heels and immediately heads for his room, with no regard to Giyu on the other side of the door.

He's probably still holding his arm up like the idiot he is. Sanemi face turns smug at the thought.

Idiot.

His walking comes to a halt when he hears repeated knocks at his door.

“Fuck off ponytail!” Sanemi shouts back at the door. The knocking stops and Sanemi assumes he's decided to leave, but when he turns back to go to his room he hears the knocking on his door start again. He heaves a sigh and walks back angrily. Opening the door, sure enough the bastard was still there.

“Do you know what time it is?” he snarls at Giyu.

“It's still fucking dark out you moron!”

Of course nothing on his emotionless face changes since he first opened the door, and that irritates Sanemi greatly.

Curse him and that stupid dumb face of his.

"I brought you this" Giyu says, opening his mouth for once.

“If I take that will you leave me the fuck alone?”

“Maybe”

Sanemi scowls at him and snatched the bag from his hand. He intended to shut the door on his face again but thought twice about it. If Giyu intended on staying the fucker would just keep knocking. He glances at the bag and then to Tomioka who looks expectant to see him open it.

He raises an eyebrow at Giyu suspiciously and hesitates on opening the bag for a moment. Tomioka has never pulled any pranks or anything on him before so it isn't likely that it would be something like that, hes probably too dumb for pranks anyway. But for some reason he felt a bit apprehensive at opening it.

He narrows his dark amethyst eyes at ocean blue ones that show distrust, despite Giyu never trying anything besides annoying him.

"What's in this?" He shakes the bag to insinuate what he's talking about.

"It wouldn't be in a bag if I wanted you to know right away"

"Tsk, smartass" Sanemi mumbled under his breath.

Sanemi looks at the bag in his hand again before lifting the folded flap and slowly opening the bag so he can peer into it. The first thing he noticed was the wafting smell coming from the bag. How he hadn't smelled it beforehand boggled him, but he blamed his still tired state.

Was it what he thought it was?

There was no denying the smell. He could recognize it from anywhere. Sanemi reached in taking one in his hand and pulled it out. He stared at the onigiri in awe for a moment before remembering that Giyu was still there. He looked up and It was very subtle, but he could see the small curve of Tomioka's lips.

"Why-"

"Happy Birthday Sanemi"

Sanemi blinked. Once, twice, even a third time. His mind had gone blank and he had to think for a minute. His mind was so caught up in his sleepy haze he didn't really have the time to think about the day. How could he have forgotten?

Sanemi furrowed his eyes, looked away and scowled.

“If you wanted to give me something why do it so damn early? Can't you be like normal people?”

“Because you'd probably expect it knowing it was your birthday, it would have been a better surprise if it was the first thing you woke up too”

Sanemi gave him a look.

The idiot.

One way or another, he wouldn't have expected a gift from anyone, whether he knew about his birthday or not. Especially from him. Sanemi glances at the onigiri in his hand with a solemn gaze.

"Try it"

Sanemi hesitates but the delicious smell hanging in the air reels him in. He brings it up and takes a bite.

It's good.

There's no way Giyu would have made this, it tasted exactly as the Kamado family's recipe. In fact, it probably was, and he had no doubt about it. He looks up to see Tomioka's smile.

"How is it?"

Sanemi looks away, avoiding eye contact with the long haired male.

"Thank you" he says in something short of a whisper.

Giyu was about to say something, probably as to what Sanemi had said when footsteps were heard behind Sanemi.

"Aniki, what are you doing up at five in the morning?"

Sanemi's body suddenly becomes rigid again and the soft expression on his face hardens as he glares at Giyu. The dark haired boy isn't fazed at the sudden change but he does blink in confusion at it.

"For the last time ponytail go away"

Sanemi shuts the door on Giyu once more, this time using his foot as both of his hands were occupied. He turns around to see Genya, who seems to look around awkwardly as if he came into a conversation he shouldn't have.

"Uh, sorry were you in the middle of something?"

Sanemi's grip on the paper bag tightens and he wrinkles his nose at his younger brother with a look. Genya takes it as a sign not to ask anything more.

"Whatever, I'm going back to bed. If you wake me up I'll kill you" he gives him a glare to seal that promise and makes his way back to his room. Genya watches his brother's retreating form curiously with the bag and onigiri in each hand.

Sanemi walks into his room and sits at the edge of his bed. He takes another bite of the rice ball as he stares at the paper bag he set on his nightstand.

Sanemi sighs, and he relaxes in the comfort of his room. He looks at the little bit of onigiri left. And he feels a warmth dust over his face.

 
Idiot.
