Summary
"Dazai continued to try and catch his breath, shifting uncomfortably, eyes still as wide, staring at the ceiling, "I have a challenge for you." he heard Chuuya say, looking back at him.
"How long?" Dazai asked, already knowing what Chuuya wanted to do.
"Three days."

Summary
Maybe he is lesser of a man.
The space between door and bed disappears as automatic steps carry Chuuya to the plush surface where he half collapses onto his ex-partner, propped over Dazai's body. One knee rests on the bed, his other foot holds sturdy on the floor, and his arms cage in Dazai's shaking figure while he watches in complete bewilderment as his name becomes louder, more frequent and lustful.
"Chuuya, Chuuya, Chu—"
"Oh shit…" the aforementioned mumbles to himself, eyes bouncing all over sweat-covered features. "You are an omega."

Summary
Gravity Hotels and Casinos: the castle of Chuuya Nakahara. From Yokohama to the Las Vegas strip, the sun never sets on Chuuya's empire. But with the gambling, the money, the drugs, and the sex- came a messy divorce, a few DUIs, a couple stints in rehab, and hundreds of burned bridges.
After getting his driver's license back, Chuuya's sister, Kouyou, lets him take his nephew to Chuck E. Cheese after school. Obviously, to get the best prize and thus buy his nephew's affection, Chuuya (kinda-sorta) tries to rob the place (not his idea, not his fault).
Luckily, the handsome, bandaged man behind the arcade counter won't call the police- on one condition:
Chuuya becomes his new sugar daddy.

The Things We Do Instead of Saying I Love You by Lqzola
Fandoms: 文豪ストレイドッグス | Bungou Stray Dogs
05 Feb 2026
Tags
Summary
Valentine’s Day is supposed to be about love, chocolate, and confessions.
Unfortunately, Chuuya Nakahara is dating Dazai Osamu.
Every year, Valentine’s Day becomes an unspoken competition, one neither of them will ever admit to, but both are fully committed to winning. Chocolate is unacceptable. Flowers are surrender. And giving something “normal” is a guaranteed loss.
As Valentine’s Day creeps closer, Chuuya finds himself spiraling over the perfect gift while Dazai remains suspiciously calm (not really).
What should have been a simple exchange of affection turns into an all out war of sentimentality, pride, and ridiculous overthinking.
A fluffy, comedic Soukoku Valentine’s Day special about love, rivalry, and two idiots who refuse to do romance the easy way.

Summary
While rare, a bond between two alphas has the potential to change one participant’s secondary gender into that of a beta or an omega. The process is almost guaranteed success if said participant is mentally willing to accept such a role, but there is no formula or absolute method to cause a change in one’s biology.
Panic strikes Chuuya like a knife through the gut. He locks his phone and borderline throws it on the table before beginning to pace the length of his bedroom.
What the hell did he do?

Summary
“There it is,” Chuuya said softly. “You feel that?”
Dazai’s ears flattened completely now, tail twitching in short, betrayed jerks. “Chuuya is doing this on purpose.”
“Yes.”
That honesty knocked something loose. Dazai twisted, turning his head just enough to glare back at him—eyes blown wide. “Chuuya likes this.”
Chuuya leaned closer, voice dropping. “I like you like this.”
Dazai pushed up onto his hands, climbing into Chuuya’s lap without asking, knees bracketing his hips. He was breathing harder, heat beyond obvious now—flushed, glossy, needy in a way he’d stopped trying to hide.
“This is unfair,” Dazai said hoarsely, grinding down without even pretending it was an accident. “Chuuya knew I was close.”
Heat makes Dazai soft, pliant, and soaked. He claws at the sheets and purrs for it while Chuuya fills him up, nice and deep, just how a good kitty deserves.
or: dazai wants to be fucked full and praised like a pretty pet. chuuya’s more than happy to indulge.

“Chuuya?” he asked tiredly.
“Mm?”
“Are you still mad?”
Chuuya shook his head, pressing his cheek into Dazai’s hair. “No,” he said. “I was. I’m not now.”
Dazai nodded, eyes drifting shut. They stood there for a while longer, neither in a hurry to move. Chuuya’s hand traced slow, absentminded paths along Dazai’s back—grounding, familiar. Every so often, he pressed a kiss into his hair or the curve of his neck, like he was checking that Dazai was still there.
He was.
or: Dazai dissociates in the shower after a bad fight. Chuuya follows him in, apologizes, fucks him gently and not-so-gently, and then takes care of him until the night goes quiet again. Sex happens, but mostly this is about staying.

Ranpo glanced up again, idly licking powdered sugar off his fingers. “You’re not gonna drop dead or anything, are you?”
No answer.
That alone should’ve been the red flag.

SMACK.

Summary
"I said, what's your name?"
Dazai snaps to attention to see that Chuuya is staring right at him, and suddenly his mouth feels like sandpaper.
Jesus. Who has eyes like that?!
“Ozai—"
“Huh?”
“Dazoo—"
“I’m sorry, what?”
“Dazai Osamu.”
Sometimes--the worst introductions can last a lifetime.

Summary
Convinced that Dazai died during a mission with the Agency, Chuuya unleashes Corruption. Too bad that Dazai has no intention of letting his partner die.
“So—” Dazai said, voice thick as velvet. “You weren’t worried at all, Slug?”
“Not worried at all. Don’t get ideas."
(“I thought I lost you.”)

And then there are some “I love you”s that are on the tip of his tongue, lodged between his ribs and carved into his bones, ready to be given away at any given moment whether it’s after a peck on the lips, while watching someone inspect empty cocktail glasses… or when they are balls-deep inside him and all Chuuya can say is —
“Oh, fuck.”
OR, Chuuya and Dazai and some of their firsts. (A 'This Side of Paradise' Epilogue.)

“When was the last time you went potty, Chuuya?” Dazai made sure the word came out mocking and babying, a sly grin clear on his face.
“Fuck off,” Chuuya hissed lowly. “Just say bathroom like a normal human being–”
or Dazai makes Chuuya piss himself on a puppy pad and then Chuuya humps his shoe. No, I'm not joking. I have so many regrets.

Summary
“Dazai, what the fuck is this?”
Brown eyes, still cloudy, peered up at him as if the words hadn’t even been comprehended in Dazai’s mind. His head cocked to the side in a silent question and Chuuya moved to push Dazai’s leg up a bit further, bringing it into the light so they could both see properly.
The near entirety of the skin was marred, of course, self-inflicted scars crisscrossing each other, old enough to have turned a faded white, but that wasn’t what he was focused on.
The issue lay in a series of fresh ones. They were scarily recent, probably only a few days old at best, and scabbed over. None looked bad enough to have needed stitches but they were pretty damn close.
Those hadn’t been there the last time they’d done this. In fact, nothing of the sort had been there any of the times they’d fucked since before Dazai left the Port Mafia.
…
In which Chuuya and Dazai have been having casual sex for years and all of that is fine until Dazai relapses for the first time since leaving the Port Mafia.

Summary
Something bubbled up in his throat, small and thin and tasting vaguely like dirt, and Dazai spat out whatever it was with blood still sticking to his tongue and teeth.
He paused.
There in the grass, stained red and mocking him with its delicate innocence, was a pink petal.
Or, Dazai is only sixteen when he begins coughing up flowers. It takes him eight years to find a cure.

The incessant banging on his door continued. Dazai grumbled to himself about common courtesies, then shuffled across the dorm and swung open the door.
The sight punched the breath from his lungs.
Standing in the doorway, gripping the frame with one hand while the other clutched a haphazard handful of bloodied bandages to his stomach, was Nakahara Chuuya.
Or, Dazai receives a late-night visitor. Being partners comes just as easily as it used to.
