Summary
He didn’t know why he was so nervous. Chuuya had seen him two weeks ago when the bastard let himself be captured by the Mafia—there was no reason for him to act like a schoolgirl about to confess to her crush. He was a grown ass man, he could handle this.
But even the idea of having a conversation with that piece of shit—
Fuck it.
With a deep breath, Chuuya slowly turned the door handle with unsteady hands. The entire world seemed to go silent except for the hinges faintly creaking as it finally opened.

Summary
Dazai Osamu and Nakahara Chuuya have spent years trying to outdance each other.
When they’re cast as the romantic leads in Swan Lake, their rivalry turns into a problem the entire company has to deal with—especially when the choreography demands trust, closeness, and a kiss neither of them wants to acknowledge.
Set in a modern ballet company where talent bleeds into obsession, this is a story about ambition, devotion, late-night rehearsals, injuries, and what happens when two people who refuse to yield are forced to move as one.

Summary
Chuuya swallowed and shifted his hand, slow and careful, letting his fingers slide into Dazai's hair. It was softer than it had any right to be—always was, even as it perpetually carried the faint scents of gunpowder and something metallic.
He brushed it back from Dazai's temple, thumb grazing skin that was still warm despite everything, and Dazai stirred, a quiet sound slipping out of him before he could stop it. His arms tightened reflexively around Chuuya's waist, face pressing closer, like he was chasing heat even in his sleep.
“Yeah, yeah,” Chuuya murmured under his breath, barely louder than a thought. “I'm here. Don't get all clingy about it.”
or: dazai doesn’t sleep until he does.
weeks of fatigue catch up to him at once, and he ends up on chuuya’s couch, exhausted enough to stay there. chuuya likes how this part goes just a little too much.Hurtcember 2025 - Day fourteen - Fatigue

Summary
Dazai's life has been a fucking mess. He can no longer count the times he's been fucked over, (literally and figuratively), the scars on his body seem even uglier, and the mixed drug concoction he downed isn't helping his migraine either. God, why couldn't Odasaku be here to deal with this shit? To top it all off, his guilt of leaving the Port Mafia hasn't subsided! If only he had a rope lying around right now. Maybe messing with Chuuya will brighten his day! But who's that looming in the distance? Oh... it's Akutagawa and Mori trailing behind the hat rack. Guess the day's only going to get worse.
**NOTICE. ATSUSHI IS 15. AKUTAGAWA RYU AND GIN ARE TWINS AND 15 FOR THIS FIC. Q IS 5. EVERYONE ELSE IS STILL THE SAME AGE. TRIGGER WARNINGS WILL BE AT THE TOP OF CHAPTERS.**

Summary
After sixty-two hours of non-stop work, all Chuuya wants is his bed. What he gets is his traitorous ex-partner curled up on his expensive suede sofa, delirious, shivering, and bleeding out from a wound that smells like rot. Dazai is hiding—from the Agency, from the Mafia, and from a new enemy that poisoned him with something No Longer Human can't nullify.
With all of Yokohama compromised, Dazai decided his only safehouse left was the one place no one would ever look: the penthouse of the man who hates him most. Chuuya is faced with a choice: throw the bastard out, or deal with the glowing, necrotic wound.

Summary
The famous mafia executives know as double black are sent on a mission by the port mafia boss. Their job is to infiltrate UA, a prestigious high school in Mustafu. Because Q has been rotting away in their cell for the past 2 years, they are allowed on the mission as well (and because my fav they/them does not get enough attention). The ADA overheard what the PM were going to do and wanted in. After a few meetings the PM succumbed, since the Triparte Pact obliged them to, and Ranpo was now on the mission as well. Q, Ranpo and Soukoku will infiltrate class 1A. Unfortunately, Q hasn't been in the outside world long enough to understand basis social manners. Q's behaviour, Ranpo's intellect and Dazai's typical jokes about suicide arouse suspicion form the teachers, especially their homeroom teacher, Shouta Aizawa. Will they finish this mission and leave Mustafu without any trace, or will they get caught up in friendships and feelings ?

Summary
"I am Dazai Osamu," he replied, settling into the new persona.
And that name, the new name that defined his identity, was who he was for the mission.
OR
Trapped as "husband and husband," the spy and the criminal are forced into a chaotic domestic life, bickering over boundaries while hiding their true, dangerous occupations. The stakes shatter when their secrets begin to overlap, threatening Dazai’s mission and Chuuya’s empire.
Worst of all, their sweet son, Atsushi, he hears every single lie.(Clearly a spyxfamily reference)
⚠️This story has A/B/O dynamics.
