Request/prompt: Could you make a oneshot of Dazai being jealous and wanting Chuuya's attention?

---

Dazai kicks back on the couch as he watches a particular redhead boil water.

"Y'know, Chuuya, with all the snow, I'd prefer cocoa."

Chuuya turns and looks at Dazai, rolling his eyes. "Well, there wasn't any cocoa left, so you're getting tea. Be grateful I'm making this for you in the first place."

"Mhm, mhm…"

Dazai nods his head and spaced out. He and Chuuya went out skiing with some friends of each of theirs. Chuuya was quite experienced cutting through the snow, gliding gracefully on his skis—while Dazai was not. He is currently holding some ice on his knee as compensation of sorts for the wound he contracted falling down the hill like a fool.

By the time Dazai refocuses his eyes, he looks ahead and sees Chuuya now distracted from prepping the tea, but now conversing with another boy with fiery hair.

Tachihara.

Of course.

If there is one thing people know about Dazai, it is that he is possessive. In their private time, Dazai holds Chuuya close to him and does not like letting him go, peppering kisses all over his body and marking his neck on occasion, signalling to everyone that the stunning redhead was already taken (if Chuuya didn't use his choker to cover the marks).

So, seeing Chuuya talking to someone else—especially when he is meant to be focusing on him and him alone—is not something the detective is fond of.

Dazai attempts to scramble to his feet and shoo his ex-partner's friend away, but the pain in his knee spikes him, irking him to sit back down. He has no choice but to wait, until Chuuya finishes his conversation with the attention-stealer.

After what was probably only five minutes—but felt like an hour to Dazai—Tachihara walked away, and Chuuya went back to sitting for tea bags.

Dazai paints his typical smile on his lips as he beckons.

"Chuuuuuyaaaaaa~"

Upon hearing the trilling of his given name, the redhead turns around.

"Are you cheating on me?"

"Hah?!"

"Is Chuuya cheating on me? He looked awfully absorbed in his conversation with that friend of his, meanwhile I sit here, injured."

Chuuya glares at the temporarily crippled brunette. "I was talking to a friend. Relax."

Chuuya squeezes his eyes shut as he adds, "Possessive bastard."

Dazai simply smiles at him smugly as the shorter man turns away from him and bobs the bag of leaves up and down in the cup as the boiled water ferments.

Dazai thinks now, he can finally sit back, and relax, and wait for his stunning boyfriend to come to him with delicious tea, and the pain in his leg will be easier to bare.

Until he sees a dark-haired man walking closer. The look of him immediately sets Dazai off.

This is why I didn't want to go skiing in a busy, public place.

He watches in agony as the tall man taps on his boyfriend's shoulder for attention. Chuuya turns and looks up at this man, as equally off-put by him as Dazai was.

Over the crowd, Dazai cannot make out the words the strange man says to the redhead, but reading his lips from afar, he makes out the words, "warm," "red," "beautiful," "captivated," and "heart."

That only spells trouble.

As Dazai watches the man gently grasp Chuuya's right hand and kiss his knuckles, he feels anger bubble up within him. He suddenly—more than ever before—wants to kill that man at the snap of his fingers. How dare he flirt so shamelessly with his boyfriend?!

Chuuya tears his hand free and scowls at the man, and from reading his lips, Dazai can make out quite colorful language being spoken by the redhead. He can even slightly hear his hollering.

The strange man, at that note, turns around and walks away, but a smirk stays on his lips. How Dazai wishes endless suffering upon him, whoever he is.

Suddenly, he feels a hot cup placed in his hands.

"Here's your tea, love."

Dazai looks up at the redhead in front of him, who is smiling, as if a stranger had not just tried to court him with Dazai to bear witness.

"Why, thank you."

Dazai sips his tea as Chuuya sits next to him on the couch.

Sugary.

Chuuya really remembered exactly how he liked it.

He can't help but smile. Chuuya will take to his grave how he memorizes each individual thing Dazai likes, even the slightest bit ("I don't care enough about you to remember the things you like!" he commonly says as a prevarication), but Dazai knows the truth. He knows every truth about the mafia executive he holds so dear.

Dazai looks up from his tea and into the distance and sees…

"Chuuya. That ugly man is gawking at you."

Chuuya looks into the same direction and scoffs.

"Gross. The fucking audacity."

"Never had I wanted to kill someone so bad."

Chuuya recognizes the dark gleam in Dazai's eye as he flashes a death glare back at the man making eyes at his life partner.

"Dazai, you can't talk like that. We're in public."

Then something clicks in Dazai's mind.

A perfect form of vengeance on that man, in a way that wasn't violent.

He smirks.

"Yes. Yes we are."

On that note, Dazai gently places his tea up on the side table, puts his hands on Chuuya's hips and yanks him into his lap, pulling him in for a loving kiss.

At first, Chuuya is caught off guard, but soon melts into Dazai's gentle touch. He puts his hands into the sides of Dazai's face and squirms so he's straddling him, careful to not interfere with the ice pack strapped to his knee.

Dazai cracks open his eyes slightly and relishes in the sight of Chuuya kissing him. His face always softened to a level it never could in any other circumstance. The way his cheeks flushed pink, the way his eyes were closed oh so delicately, it's a state only Dazai has the pleasure of seeing the redhead in.

And he's quite grateful for that.

Dazai gently pulls away from the redhead and looks into his eyes.

"That was for the man hitting on you."

Dazai then leans in again, but targets Chuuya's neck. He moves his choker out of the way and licks at a spot above his clavicle, and then gently bites the skin there, and with the same tenderness, begins to suck on the spot, warranting an embarrassing noise from the redhead.

Upon leaving a satisfying mark, Dazai changes to kissing at the marred skin, until he is fully satiated. He pulls away and looks into Chuuya's flustered eyes, and smirks.

"And that was for talking to Tachi instead of me."

He tucks a tendril of fiery hair behind Chuuya's ear.

"I got hurt out there, Chuuya. You should be putting all your attention on me."

Chuuya puffs his cheeks in annoyance. "Sh-shut up. I'll talk to whoever I please, you possessive son of a bitch."

Dazai laughs. "Aww, Chuuya, you're such a tsundere! It's adorably embarrassing~"

Chuuya sputters for a bit, and then gets an idea.

"You really feel that way, hm?"

He rolls his hips and is humored by the groan Dazai lets out.

"I'll show you the truth."

"Ch-Chuuya, we're in public."

"You got a problem with that?"

Dazai surveys the area. Little to no people have their attention on the two of them. But, so what if they did? Dazai has nothing to hide.

"Most certainly not."

"I'll show you what I think of your name-calling, possessive Dazai."

And he leans in, kissing Dazai once more, giving him the attention he longed for so strongly their entire getaway.
