When Dazai and Chuuya were fifteen he could never understand how people left Dazai under the guise that he was too depressed or suicidal for them to handle.
Now that he was twenty-three, no, twenty-fucking-four. He understood.
But he would never dare leave his husband over something as ridiculous at that, he isn't responsible for his shitty mind. And though he might think about it, when he arrives home late on Chuuya's birthday looking awfully akin to a wet cat he knew he would never think to abandon his lover.
In a few long strides Dazai arrived in front of Chuuya and wrapped him in a tight hug, holding on as if he were his lifeline.
And, well, in situations like this he probably was.
"Fucking hell 'Samu... you're soaked" It wasn't just rain; he wreaked of river water too.
Dazai made a sound almost identical to that of a displeased feline and pulled away from Chuuya.
"'Didn't mean you had to pull away..." Chuuya mumbles, taking Dazai's hand in his and running his fingers along his palm. "Here's what we're gonna do: I'm gonna run a nice, warm shower for you, we're gonna get somethin' in that fucking stomach of yours, and see where the night takes us. You can visit Oda's grave in the morning or Lupin or whatever but you're fucking crazy if you think I'm letting you go back out in that weather."
Dazai looks at Chuuya expectantly. When he realized Dazai wasn't going to do any of this himself he decided to just drag the stupid mackerel along. He helped him out of his wet clothes, gently peeling back the layers until he was at his bandages.
"Osamu..."
"You don't have to ask every time, stupid slug." His voice was weak and raspy, but they were the first words Dazai had spoken all night and they made Chuuya feel at ease.
"Right...'' With that Chuuya carefully removed the bandages and shoved Dazai into the bathroom, he turned around to leave when bony fingers wrapped around his wrist willing him to stay. "I'll... be right back. I'm just going to grab you some clothes."
Dazai huffed but still removed his grip and allowed Chuuya to retrieve the clothes. When Chuuya came in he sighed upon realizing Dazai was just standing there stupidly under the running water. Begrudgingly, he began to work soap into scarred skin, taking extra care to rinse conditioner out of uncared for waves, when he saw the glimpse of something behind Dazai's left ear.
"...What's that?" Chuuya asked dumbly, brushing the hair from Dazai's ear.
"...A tattoo." Dazai responded stiffly.
He scoffed. "Obviously. It's a dog... Osamu you hate do- Oh. Oh."
Chuuya blushed as he helped Dazai out of the shower and began to dry him off using one of the soft towels Dazai loved.
He began to wrap bandages around Dazai's neck when a hand came up to stop them. "I don't need them. It's just Chuuya."
Chuuya smiled softly and pressed a small kiss to Dazai's jawline, intertwining their fingers as he dragged Dazai to the kitchen.
"What can you stomach tonight?"
Dazai hums and buries his face into Chuuya's neck, his hands traveling up Chuuya's shirt. "I can't."
"Sweetheart, you have to eat someth-'' his breath hitches, "stop fucking doing that 'm tryna talk to your shitty ass."
"Unless Chuuya wants to deal with my upset stomach all night I advise he leaves the topic alone."
Chuuya purses his lips, not quite ready to drop the subject. "But..."
"Ah, ah, ah! No buts. Now pour yourself a drink and let me give you a shoulder rub, chibi seems stressed."
"Lay off my height!" Chuuya begrudgingly removes himself from Dazai's grasp, "That does sound nice..."
Chuuya pours himself a glass of red wine as Dazai gets comfortably on the couch. He scoffs affectionately at the sight and settles himself in between Dazai's legs.
"Happy birthday mutt, I'm sorry I ruined your special day."
Chuuya hums and melts against Dazai's hands, wishing he could disappear into his warmth. "You didn't ruin it, shitty mackerel. My birthday hasn't been special since we were eighteen."
"What about twenty-one? Weren't you excited to be legally able to drink?"
Chuuya scoffed and rested his face on Dazai's thigh. "No. Twenty-one might've been my worst birthday."
"Oh?" A hand moves to gently card through auburn curls.
"Because you weren't there."
Dazai tenses up at the confession, unaware of what to say when Chuuya suddenly nuzzles Dazai's thigh, causing his hair to fall away from his neck. "...Demon Prodigy."
"What?" Chuuya paused. "Oh. Oh..."
"Is that a new catchphrase? It isn't quite as endearing as 'I'm fifteen, damn it! I'm still growing!'"
Chuuya bites into Dazai's thigh in retaliation. "Shut the fuck up!"
"Ow! Bad dog! Bad!"
"And I'll fucking do it again you over-sized mummy!"
"I'm not even wearing any bandages! And I'm not over-sized you're just fun-sized!
Chuuya scoffs. "Whatever! Fuck off about the tattoo you jackass."
"But chibi can ask about mine?"
Another scoff. "Fucking fine! But you only get one question, ya hear me!?"
"When did you get this?" He ran his fingers over the lettering causing Chuuya to shudder.
"...After you defected."
"Ah. My dog wanted the whole world to know he belonged to me"
"Oi! Watch it jackass! I'll bite you again!"
"Does Chuuya want me to shut up?"
Chuuya hums, opening his eyes when he feels Dazai's face close to his. "...Yeah. I do you fucking menace."
"Then... your wish is my command. Happy birthday, darling." He closed the gap between the two, kissing Chuuya in a way that made him feel breathless and sickeningly fifteen again.
He pulled away with a lingering hand cradling Chuuya's cheek.
"Again."
