Work Text:
The rain fell steadily against the windows of the Armed Detective Agency, soft drizzles tapping the glass in a sleepy rhythm. The office was unusually quiet—Ranpo was sprawled on the couch with a lollipop in his mouth, Kunikida was already typing away at his laptop, and Dazai was doodling dramatic suicide notes in the margins of a mission report.
The door creaked open.
Atsushi stepped inside, shoulders damp, silver hair sticking slightly to his forehead. He was bundled in his usual worn coat, but there was a tiredness in his eyes, a slight flush on his cheeks, and a faint sniffle he tried to stifle.
“Good morning,” he murmured, voice hoarse but polite as always.
Kunikida looked up immediately. “You’re late by seven minutes, Nakajima. And—wait, are you sick?”
“N-No, I’m fine!” Atsushi quickly replied, waving a shaky hand. “Just a little cold from the rain…”
“You look like a soggy tissue,” Ranpo chimed in without looking up. “You’ve got fever-face.”
“I said I’m fine,” Atsushi insisted with a wobbly smile. “Really. I’ll just, uh, get started on the reports…”
“Like hell you will,” Yosano’s voice called from behind, calm but firm as she stepped out of her office. “Sit. Down.”
Atsushi froze mid-step.
“But—”
“No buts,” Yosano crossed her arms. “You’re burning up. I can see the heat from here. Don’t make me drag you to the couch.”
Dazai chuckled, spinning in his chair. “Ooh, Yosano-chan’s in doctor mode~ Better listen, Atsushi-kun, or it’s the scary kind of treatment next.”
“I—okay,” Atsushi mumbled, too tired to fight back. He trudged over to the couch and flopped down with a small sigh, cheeks pinker than usual from both fever and embarrassment.
Kunikida sighed, already typing a new schedule into his notebook. “Unbelievable. Rainy season always brings this nonsense.”
“I think he looks cute when he’s all sleepy,” Kenji beamed, coming in with a warm bag of steamed buns. “I’ll go get him some soup!”
As the rain continued to fall outside, Atsushi slowly relaxed into the cushions, the warmth of the office and the gentle buzz of his found family surrounding him.
Wrapped in a soft blanket Kenji had unearthed from the supply closet, Atsushi lay on the couch like a wilted cat. His eyelids drooped, but he tried to stay alert—partly from guilt, partly from habit.
“Don’t even think about getting up,” Yosano said as she placed a cool cloth on his forehead. “Your job for today is to breathe and not faint.”
Atsushi mumbled something in protest, but it came out as a sleepy wheeze.
Dazai popped into view, leaning over the back of the couch dramatically. “My dear Atsushi-kun, if you wanted attention, you could’ve just faked your death like a normal person.”
“Dazai,” Kunikida snapped without looking up.
“What?” Dazai pouted. “All I’m saying is: if he wanted the day off, there are much more theatrical ways to go about it.”
“You’re not helping,” Yosano muttered.
Ranpo strolled over, sucking on a new lollipop. He eyed Atsushi with mild curiosity before digging into his coat pocket. “Ah. I have just the thing for this.”
He pulled out a wrapped piece of candy with a bright red wrapper and dropped it into Atsushi’s hand. “Here. Recovery candy. I think it’s strawberry... or maybe chili pepper. I forgot.”
“...Should I eat it?” Atsushi asked uncertainly, blinking up at him.
Ranpo shrugged. “Fifty-fifty chance it heals you or makes your nose run more. Life’s a gamble.”
“Don’t give him that,” Yosano said flatly. “You have no idea what that even is.”
“I found it under my hat last week. It’s probably fine,” Ranpo grinned.
Atsushi gave a tiny, hoarse laugh. “Thanks... I think.”
Kenji returned triumphantly with a tray carrying a warm bowl of soup, a water bottle, and a rice ball. “I got your favorite! It’s got daikon and tofu and everything!”
Atsushi sat up slowly, overwhelmed but touched. “Thank you, Kenji-kun…”
Kyouka quietly placed her bunny plush on the arm of the couch beside him. “For comfort,” she said, then sat down and opened a book, pretending not to watch over him while absolutely doing just that.
Dazai plopped down dramatically beside Atsushi’s feet. “So unfair. I cough once and you all ignore me, but Atsushi sneezes and it’s a full nursing team.”
“Because when you cough, it’s because you tried to drink expired sake from the back of a dumpster,” Kunikida muttered, typing furiously.
“You wound me, partner!”
Despite the chaos, Atsushi felt a strange warmth—not from the fever, but from the care surrounding him. The soft clatter of cups, Ranpo’s candy antics, Kenji’s innocent cheer, Kunikida’s grumbling efficiency, Yosano’s gentle firmness, Kyouka’s quiet presence, and Dazai’s dramatic nonsense—each gesture stitched itself into a quilt of comfort over his aching body.
And for the first time that day, he let himself relax.
Despite the soup, the blanket, and Ranpo’s highly questionable candy, Atsushi’s fever hadn’t gone down. In fact, by late afternoon, it was clearly worse.
Yosano gently pressed a thermometer to his ear and sighed when it beeped.
“39.5°C. That’s it—he’s going home.”
“But I can still—” Atsushi began weakly.
“No, you can’t,” Kunikida cut in. “You’re sweating and shivering at the same time.”
Dazai leaned over the back of the couch again, brow raised in mock concern. “Hmm, do you think if he passes out, we can use it as a team-building exercise?”
“Dazai,” Kunikida growled.
“I was joking! Mostly.”
“We’ll take him to his apartment,” Yosano said, already packing up medicine and a thermometer. “Someone needs to stay with him.”
“I’ll go,” Kyouka said softly, immediately.
“Me too!” Kenji added with a grin. “I’ll make porridge!”
“I’ll supervise,” Ranpo yawned. “And eat the leftovers.”
Dazai raised a hand. “I volunteer as emotional support.”
Kunikida pinched the bridge of his nose. “I’ll go as well. Someone has to make sure the house is still standing afterward.”
---
Later That Evening – Atsushi’s Apartment
Atsushi barely made it through the door before he was guided to bed by Kunikida and Yosano, wrapped in a second blanket and tucked in like a burrito. He mumbled sleepy thanks, face flushed with both fever and mild embarrassment.
Kyouka sat on the edge of his bed with a fresh towel for his forehead. Her usual stoic expression softened as she quietly replaced the damp cloth and brushed his bangs aside.
“You always take care of everyone,” she said. “Let us take care of you.”
Kenji bustled in with a pot of steaming rice porridge, followed by Ranpo who had somehow found another lollipop and was now lying sideways on the couch like he lived there.
“I brought soup and also stole your snacks,” Ranpo declared.
Dazai dropped into a beanbag chair on the floor with a dramatic sigh. “This feels like a sleepover! Except instead of truth or dare, we’re playing ‘keep Atsushi alive.’”
“You’re all too loud,” Kunikida muttered, setting down a humidifier. “Let him rest.”
Atsushi peeked through heavy eyelids at the strange collection of people filling his tiny room. It was cramped. Warm. Alive.
He couldn’t remember the last time he had been sick and felt safe.
His voice was barely a whisper. “Thank you, everyone… really.”
Dazai, for once, gave a soft smile. “You’re part of the Agency, Atsushi-kun. You don’t have to be strong all the time.”
“Yeah,” Kenji beamed. “We’re family!”
Yosano checked his pulse gently. “Now sleep. You’ll feel better tomorrow.”
Atsushi let out a quiet breath and finally let his eyes close. He drifted off not to silence, but to the low sound of his friends bickering, cooking, reading, and staying close by—watching over him like a mismatched, loving family.
The room had grown quiet as night blanketed the city. The others had dozed off where they sat—Kenji curled up on the floor with a blanket, Kunikida asleep upright in a chair with a book on his chest, Ranpo snoring softly on the couch, and Kyouka leaning against the bed frame with her eyes closed.
Dazai sat cross-legged on the beanbag, still awake, watching Atsushi with quiet intensity. The younger detective’s fever hadn’t spiked again, but his sleep had grown restless. Sweat clung to his brow despite the cool cloth, and his hands gripped the blanket tightly.
Then, it started.
A low whimper.
A twitch.
Then, words—ragged and barely audible, but heavy.
“Please… don’t lock me in again… I didn’t mean to eat it… I was just hungry, I swear…”
Dazai stood in an instant, eyes narrowing. He moved closer and reached out. “Atsushi.”
Atsushi flinched, still trapped in his nightmare.
“I’ll be better… I promise… please don’t hurt me…”
Dazai shook his shoulder gently but firmly. “Atsushi. Wake up. Hey—it’s not real.”
Atsushi’s eyes snapped open, wide and wild. He tried to sit up but was too dizzy, chest heaving, panic painted across his face like a fresh bruise.
Dazai caught his shoulder. “Hey, hey. You’re safe. It’s okay. Just a dream.”
Atsushi blinked rapidly, eyes wet. “Dazai…?”
“Yeah. It’s me. You’re not at that place anymore.”
Atsushi’s throat tightened. “It felt so real. I could smell the mold on the floor… hear the chains…”
“I know,” Dazai said, his voice uncharacteristically gentle. “But you’re not there. You’re here—with us.”
The panic began to ease from Atsushi’s eyes. He looked around the room, at the soft glow of the lamp, at Kenji’s peaceful sleep, at Kunikida’s book-laden lap, at Kyouka still resting nearby.
“...I’m not alone.”
“No,” Dazai said. “You’re not.”
Without a word, Dazai sat beside him on the bed, letting Atsushi lean against his shoulder. “You don’t have to keep fighting that battle in your head every night. We’ve got you now.”
“…Thanks, Dazai-san.”
Dazai smiled faintly. “Anytime, little tiger.”
Atsushi drifted back to sleep slowly, this time with no chains, no yelling, no cold floors—only the quiet breathing of the people who had become his family, and the warmth of someone who refused to let him face the darkness alone.
The second time Atsushi drifted off, it was different.
No cold floors.
No yelling.
No guilt that bit like frost.
Just the sound of breathing—gentle and real. The scent of rice porridge still lingering in the air. The weight of a blanket tucked securely around him. And beside him, the warmth of someone who didn’t leave.
Dazai hadn’t moved far. He sat back in the beanbag, legs crossed, a book balanced lazily in one hand. The room was quiet except for the occasional snore from Ranpo and the soft rustle of pages turning.
Outside, the sun had begun to rise, casting gentle rays through the curtains. It painted the room in soft gold, glinting off Yosano’s glasses where she slept in the corner, off the buttons on Kunikida’s vest, and the pale strands of Kenji’s hair.
Atsushi stirred slowly, blinking up at the ceiling.
No panic.
No heaviness in his chest.
Just stillness—and a strange, tender ache in his heart. The kind that only comes when you’ve been cared for in a way you forgot was possible.
He turned his head slightly. Dazai hadn’t looked up, still absorbed in his book, but Atsushi could tell. He knew he was awake.
“…Morning,” Atsushi whispered, voice a bit hoarse.
Dazai didn’t move for a moment, then flipped the page. “Morning, sunshine.”
Atsushi gave a small smile, barely there, but real. “You didn’t… leave.”
“Of course not.” Dazai’s voice was light, but not joking. “I couldn’t risk Kunikida waking up and finding me gone. He might write me up.”
Atsushi chuckled softly.
Dazai finally looked over, eyes meeting his. “You slept better this time.”
Atsushi nodded. “Yeah… I did.”
Neither of them said anything about the nightmare. Not the shaking, not the tears. It didn’t need to be spoken aloud. It had passed.
Atsushi sat up a little, glancing around at the others, all still sleeping in various positions—some elegant (Kyouka), some chaotic (Ranpo).
“They all stayed too?”
“Yep. Even Ranpo, though I had to bribe him with candy.”
“…They really didn’t have to.”
Dazai tilted his head. “They wanted to. That’s kind of the point, Atsushi-kun.”
Atsushi let the silence settle in again, this time comfortably. He didn’t feel like a burden. He didn’t feel alone.
Just… warm.
Safe.
Home.
One by one, the detectives began to stir as the morning sun grew brighter.
Kunikida was the first to rise, of course—his internal alarm clock never failing. He stretched, blinked at his surroundings, then sighed when he saw Dazai still in his beanbag chair.
“You stayed up all night again, didn’t you?” he muttered, walking toward the kitchen.
“Not true,” Dazai replied, flipping a page. “I rested my eyes between chapters.”
Kunikida rolled his eyes and started quietly preparing breakfast. Soon, Yosano joined, tying her hair back with a loose ribbon and offering to help with miso soup. Kenji wandered in, bright-eyed as always, and began chopping vegetables with surprising speed. Even Ranpo contributed by handing out plates—after confirming there were snacks somewhere in the deal.
By the time Kyouka woke and wandered sleepily into the kitchen, the table was already full of warm food and quiet chatter.
Atsushi was still sitting in bed, propped up by pillows, watching them all move around like it was the most natural thing in the world. Like this had always been his home.
“Come on,” Kenji said cheerfully, helping him up. “You gotta eat. You’ll get stronger!”
Atsushi hesitated, then nodded and joined them at the table. It was a tight fit, with everyone squished together on cushions, but no one seemed to mind. The warmth in the room was richer than the soup, sweeter than the rice.
“Feeling any better?” Yosano asked, offering him tea.
“Yeah. A lot better. Thank you… all of you.”
“You should get sick more often,” Ranpo said, mouth full. “This is the best breakfast Kunikida’s made in weeks.”
“I made the soup,” Yosano said pointedly.
Ranpo shrugged. “Same thing.”
They laughed, and Atsushi laughed too—quiet, but honest. For a moment, everything was light.
But after breakfast, when the others began cleaning up, Kenji innocently wandered into the hallway and peeked into Atsushi’s kitchen.
“…Hm?” he murmured. “Why is there only one cup?”
Dazai looked up.
Soon, Kunikida noticed too—the fridge was nearly empty. The only “furniture” was a mattress and a small table with two wobbly legs. There were no decorations. Not even curtains.
Yosano opened a cabinet. One bowl. One spoon. One fork. All old, mismatched pieces.
Ranpo frowned. “Atsushi… is this really your whole place?”
Atsushi froze. His fingers clenched slightly around his teacup.
“I—it’s fine. I don’t need much,” he said quickly. “I’m used to it.”
Silence stretched through the room like a wire pulled too tight.
Dazai didn’t speak, but his gaze softened as he stood and walked over. “You know,” he said gently, “having just one of everything… kinda makes you seem like you never thought anyone would stay.”
Atsushi looked down, embarrassed. “I guess I didn’t.”
No one said anything for a moment. Then Kenji smiled softly and said, “Well, now you’ll need more plates. For when we visit.”
“And a second futon,” Kunikida added, adjusting his glasses. “For emergencies, of course.”
Yosano nodded. “And a proper cabinet. I’ll help you pick one out.”
Ranpo popped a candy in his mouth. “And snacks. You seriously don’t have any snacks.”
Atsushi blinked at them, overwhelmed.
“…You’re really going to come back?”
Dazai smiled, hand ruffling his hair. “Try and stop us.”
The day after Atsushi was back on his feet, Dazai clapped his hands together with a suspiciously bright grin.
“Alright, everyone! Field trip!”
Atsushi blinked. “Huh?”
“We’re going shopping!” Dazai announced. “Operation: Make Atsushi’s Apartment Less Depressing begins now.”
“It’s not depressing,” Atsushi mumbled, but his blush betrayed him.
Yosano had already tied her coat stylishly and grabbed her bag. “We’ll need kitchen supplies. Plates, pans, proper knives…”
Kunikida was flipping through his notebook furiously. “I’ve already made a list. You’re lucky I’ve been waiting for an excuse to fix that excuse for a kitchen.”
Kyouka silently stood up and handed Atsushi his shoes. “You need curtains,” she said simply.
Kenji cheered. “And plants! Plants make everything happy!”
Atsushi looked like he was about to melt into the floor.
“What about you, Ranpo?” Dazai asked as they stepped outside, sunlight warming their backs.
Ranpo yawned. “I’m going to the candy store.”
“…Of course.”
They split into teams once they arrived downtown.
Team Kitchen Overhaul (Kunikida & Yosano) dragged Atsushi through the aisles of home goods stores, debating plate colors with the intensity of war generals. Kunikida muttered about practicality while Yosano kept showing Atsushi plates with cat designs.
“I think this one suits him,” she said with a smirk, holding up one with a sleepy tiger.
“I don’t need themed plates!” Atsushi protested.
“You do now,” she said, dropping it into the basket.
Team Decor Squad (Kenji & Kyouka) explored the flower shop and knickknack stands. Kenji carefully chose a sunflower in a little blue pot, saying it looked “hopeful, like you.” Kyouka picked out a wind chime with a soft, pretty sound and a cheap but cute curtain with tigers on it. She didn’t say why. She just handed it to Atsushi and walked on.
Team Chaos (Dazai & Atsushi) hit the clothing store after. Dazai kept picking out ridiculous things: a sparkling purple scarf, a shirt that said “I Meow in My Sleep,” and oversized sunglasses.
“You’ll be the fashion icon of Yokohama!” Dazai declared.
“I’m going to melt,” Atsushi groaned, face in hands.
But eventually, with Dazai’s help (and surprisingly good taste when he wasn’t joking), Atsushi found a few warm sweaters and a soft jacket that actually fit. He couldn’t remember the last time he bought clothes for comfort.
Meanwhile, Ranpo returned with a massive bag of sweets and proudly announced he found the “perfect thing” for Atsushi.
It was a nightlight. Cat-shaped. With glowing purple eyes.
“You’re scared of the dark sometimes, right?” he said, chewing on a lollipop. “Now you’ve got a cat that watches over you.”
Atsushi didn’t speak. He just clutched the box and whispered, “…Thank you.”
By the time they all returned home, his apartment was bursting with life. The tiger curtain fluttered by the window. New plates clinked softly on shelves. The sunflower sat proudly by the table.
And for the first time, it didn’t feel like just “a place to stay.”
It felt like his.
Like home.
Later that night, Atsushi lay on his mattress, surrounded by the soft rustle of curtains, the gentle clink of dishes, and the faint chime of wind blowing through the new decorations Kyouka had chosen. His place looked… lived in. Like a home.
The others were still there.
Even though he’d insisted he was feeling better, the agency had voted (against his weak protests) to stay a little longer—“Just to make sure you don’t collapse on us again,” Kunikida had said, adjusting his glasses with feigned seriousness.
Yosano had set up camp on the couch, claiming medical observation. Kenji and Kyouka were curled up on extra blankets near the foot of Atsushi’s bed. Ranpo had fallen asleep with half a candy in his mouth, legs draped dramatically across a pile of floor cushions.
And Dazai… Dazai was seated quietly by the window, a book in his hands, face half-lit by the soft glow of Atsushi’s cat-shaped nightlight.
They’d made themselves at home, but not in a loud or overwhelming way. They simply stayed, filling the space with warmth and quiet companionship. As if to say: You don’t have to ask. We’re here.
Atsushi hesitated before speaking, voice soft in the hush of night.
“…You didn’t have to do all this.”
Dazai turned a page in his book, not looking up. “Of course we did.”
“I’m better now. I would’ve been fine on my own.”
“No, you would’ve survived on your own,” Dazai said evenly. “There’s a difference.”
That made Atsushi go quiet.
Dazai’s voice was calm, but not distant. “You showed up to work with a fever. You flinched in your sleep. Your apartment had one spoon. You don’t decorate or make things comfortable, not because you’re lazy, but because somewhere along the way, someone convinced you that comfort wasn’t meant for you.”
Atsushi swallowed hard.
“It’s not about spoiling you,” Dazai continued. “It’s about reminding you that you’re allowed to be cared for. You don’t have to earn every scrap of kindness.”
Atsushi stared at the ceiling, his chest tight. No one had ever said that before—not in a way that felt so real.
He turned his head slightly, catching sight of the others—his teammates—curled up around his small apartment, all staying behind just to make sure he really got better.
“…Thank you,” he whispered.
Dazai didn’t respond, just turned another page in his book, letting the moment settle like dust in quiet sunlight.
And for the first time, Atsushi let his eyes close, not out of exhaustion, but peace.
He slept deeply, not because he was alone, but because he wasn’t.
