Work Text:

The high noon sun draped the Uzumaki house in a bright glow, the soft breeze stirring the curtains gently near the open windows, carrying the scent of fresh floral detergent and freshly cut grass from the backyard. After pressing a gentle goodbye kiss to Naruto's cheek, Hinata lingered by the doorway, adjusting the strap of her bag as it rested against her shoulder.

"I'll be heading out now," she said softly. 

Naruto looked up from the kitchen as he placed the ingredients on the kitchen counter. He stood there, the familiar Hokage cloak absent for once, replaced by an apron with little puppy drawings on it, courtesy of Kakashi's birthday gift to him last year. 

"Have fun! We'll handle everything here, don't worry," he said with a wide grin and a thumbs-up. 

Himawari, who was also wearing a mini version of the apron and washing her hands on the sink, bounced lightly on her feet. "I'm gonna help daddy! I'll make sure he won't burn anything down." 

"What? I can cook, ya know. Your gramps Iruka taught me." 

Hinata laughed gently. "I'm counting on you, Hima." 

Ino had invited her, Sakura, Tenten, and Temari for a little get-together. Every once in a while, when missions, paperwork, children, and village responsibilities piled too high, the women made time for themselves. It wasn't anything extravagant, but rather just a simple ladies' day meant to help them unwind. This time, their itinerary was pleasantly modest: lunch at a newly opened restaurant everyone had been talking about, followed by a visit to a hot spring and a salon. Hinata found herself looking forward to it more than she expected. It had been a while since she'd last had her hair trimmed, the ends already brushing uncomfortably against her shoulders as summer slowly crept closer.

Life at home had been undeniably full. Two rowdy boys who seemed to make it their personal mission to test every boundary in existence, usually at their father's expense, filled the house with constant noise and chaos. Doors slammed, arguments flared, and laughter echoed down the halls in equal measure. And then there was their endlessly energetic daughter, a small whirlwind of curiosity and joy, shining like sunlight wherever she went, her presence impossible to ignore.

Somehow, all of it had left Hinata more tired than she had realized. She loved them deeply without question. Naruto did his best to shoulder his share of the burden, stepping in whenever the boys grew too wild, herding them away with exaggerated scolding and playful threats while flashing her an apologetic grin. He tried to be a good husband, a present father, even when his duties as Hokage pulled at him from every direction. Still, the exhaustion lingered in quiet moments, settling into her bones. Naruto's one-week vacation leave (approved by Shikamaru and a very bored Rokudaime) and Ino's invitation felt like a small lifeline. 

She closed the main door and stepped out of the house. Her gaze then shifted toward the backyard where Boruto and Kawaki stood beside a laundry basket nearly as tall as Himawari, the woven rim brimming with freshly washed clothes. Several shirts and towels were already scattered across the grass and draped unevenly along the clothesline, evidence of both effort and impatience. The two boys were bickering in low, heated voices. Boruto was gesturing wildly with a damp shirt in hand, and Kawaki was scowling as he reached for a clothespin with deliberate precision.

Her eyes softened, though a familiar concern crept in. She knew those two far too well by now. It would be nothing short of a miracle to return home without some kind of disaster in her absence.

"You two," she called gently and firmly. "Please behave while I'm gone. Don't cause your dad too much trouble."  

Boruto reacted immediately, throwing his head back in exaggerated misery. "We are behaving," he protested, his tone dripping in mock offense as he grabbed a shirt from the basket. "You say that like we're about to start a war or something." 

Kawaki glanced at him sideways, unimpressed, but then turned to Hinata with a sincere gaze. "Have fun today," he said simply.  

Hinata smiled appreciatively. "I will!" 

After years of experience, she had learned that reassurance from Boruto usually meant inevitable trouble was already brewing. Still, she trusted them. Mostly. With one last look, she left their home, hoping that the peace might last just a little longer. And that the Uzumaki household would still be standing, preferably intact, by the time she returned.

The kitchen soon filled with the gentle clatter of utensils and the soft bubbling of soup. Naruto stood at the stove, carefully stirring, his brow furrowed in concentration. Himawari stood beside him on a small step stool, handing him ingredients like it was the most important mission in the world.

"Hima, does this look right?" he asked, pretending to peer into the pot with worry.

Himawari, standing on a small stool beside the counter, leaned forward and sniffed. "Daddy, you're supposed to stir, not attack it."

Naruto laughed. "Mom makes this look way easier."

"I think grampa Iruka didn't teach you very well in cooking..." 

"You little minx," Naruto poked her side, making her giggle. "He's very good at cooking! I suppose I'm the one who needs more time to train in the art of cooking..."

"Daddy," Himawari suddenly scolds. "You're supposed to add the carrots after the onions."

Naruto blinked. "Oh—right. See? That's why I need you here."

She beamed proudly. "Mama says cooking is about timing and love."

Naruto smiled at that, warmth settling in his chest. "She's right. We're doing pretty good as a two-man team, huh?"

"We're gonna finish this D-rank mission in no time!"

Meanwhile, outside, the backyard told a very different story. Boruto stood with a laundry basket balanced on his hip, snapping a shirt onto the clothesline with unnecessary force. The wind tugged at the fabric, flapping it dramatically.

Kawaki, standing on the opposite side of the line, raised an eyebrow. "You're gonna rip it if you keep doing that."

Boruto shot him a glare. "Relax. It's just a shirt."

"That's dad's shirt," Kawaki replied flatly.

Boruto paused mid-snap, looked at the shirt, then shrugged. "He's got like a hundred of these."

Kawaki scoffed and clipped a towel neatly onto the line. "You're supposed to hang it evenly. If it dries wrong, it wrinkles."

Boruto snorted. "You sound like Mom."

"And you're in a mood. At least I'm doing it right."

Boruto turned toward him slowly. "You saying I'm not?"

Kawaki didn't look up. "What's gotten into you? I'm saying you're sloppy."

Boruto stepped closer, pointing an accusing finger. "Oh, you wanna talk sloppy? You clipped two socks together. Who does that?"

"They're literally a pair."

"That's not how laundry works!"

"Yes, it is."

"No, it's not!"

The wind picked that moment to knock one of Boruto's poorly clipped shirts off the line. It fluttered down and landed in the dirt.

Kawaki glanced at it, then at Boruto. "Nice."

Boruto stared at the fallen shirt, then whipped around. "You distracted me!"

"I didn't even do anything."

"You were judging me!"

"What's your problem? You've been acting all broody since this morning. What—did you and Sarada fight again? Trouble in paradise?"

"That's none of your business!" Boruto exclaimed, embarrassed. "What do you know anyway!"

Kawaki finally faced him fully, arms crossed. "Damn brat. You certainly don't need help messing things up."

Boruto clenched his fists. "Say that again."

Kawaki smirked. "What, you trynna pick a fight?

Boruto lunged. Laundry baskets tipped over. Clothespins flew. The clothesline shook violently as the two collided, grappling and shoving, their brotherly rivalry pouring into every movement. This went on for a good five minutes.

"Get off me!" Boruto snapped.

"You started it!" Kawaki shot back, elbowing him aside.

Boruto retaliated with a shove that sent Kawaki stumbling. Kawaki recovered quickly, grabbing Boruto by the collar and decking him, only to be blocked by an arm. Still, he didn't give Boruto time to breathe. Chakra flared as he rushed in again, the ground cracking under his feet. Boruto barely managed to block before getting sent skidding across the yard again, his back slamming into the clothesline pole. The line snapped loose, laundry raining down around him. Inside the house, Himawari blinked as a loud thump echoed through the open window.

"... Daddy?" she asked slowly. "That didn't sound like laundry."

Naruto paused mid-stir, sweat dropping, and sighed. "Those idiots. They're probably just fighting over something stupid again."

Outside, Boruto twisted out of Kawaki's grip and swung wildly. Kawaki blocked, irritation flashing across his face.

"Why do you always have to make everything a competition?" Kawaki growled.

Boruto scoffed. "You're the one acting like you're better at everything!"

"You keep running your mouth," Kawaki snarled, advancing, "but you can't back it up."

Boruto coughed, straightened slowly, and then smiled. Kawaki knows that smile. That smile usually means trouble is incoming.

"Oh," he said, brushing grass off his jacket, "I can back it up.  I'm not done yet."

Kawaki halted. Boruto's hands came together.

"Oiroke no jutsu!" he said, tilting his head, grin sharpening. 

Smoke burst outward. When it cleared, there stood Boruto. Except... not. Same face, hair, striking blue eyes, but unmistakably a woman version of himself, standing with one hand on her hip, the other tucking a piece of hair behind her ear, head tilted, boobs almost spilling out from the bikini top, holding them snuggly, batting her eyelashes with aggressively fake charm.

"Now, now," Boruto said in a syrupy, obviously forced tone, but undeniably a very woman's voice. "Be gentle with me Kawaki-kun!"

Dead silence. Kawaki froze, staring into the anomaly that was in front of him. Blood rushed to his head, and his face burned. Confused and terrified, he screamed.

"HAA?!"

Boruto's grin widened. A shadow clone rocketed in from the side and punched Kawaki square in the face.

"—Ggh!"

Kawaki stumbled back, shock breaking instantly as the illusion popped into smoke.

"You—!"

Boruto bent over laughing, absolutely losing it.

"It worked! I knew it would—did you see your face?!"

Kawaki snapped, chakra flaring as he lunged again. They collided, fists flying, this time no tricks but just raw brawling.

"What the hell was that?!" Kawaki shouted, dodging a punch.

Boruto ducked and countered, still laughing. "It's the Forbidden Uzumaki Jutsu!"

"That jutsu is stupid!"

Boruto skidded back, pointing dramatically. "It worked didn't it? It's a very handy jutsu, ya know!"

"Whoever made that must be a stupid pervert."

Boruto smirked. "Wait till you hear who made it."

Kawaki paused mid-stance. "...Who."

Boruto jerked his thumb toward the house. "Dad."

"... HA?!"

In the background, Naruto stood frozen in the kitchen doorway, wooden spoon clenched so hard it was cracking. His eye twitched. Himawari sighed beside him.

"Daddy, you shouldn't have taught nii-chan that jutsu."

Naruto laughed nervously. "It's one of my most basic attacks since I was a kid. Unironically, that jutsu alone almost saved the world."

"Huh. Can you teach me that jutsu then?"

Naruto's eyes widened. "Absolutely not. Don't even think about it young lady. It's forbidden."

"Oh well," Himawari shrugged.

"Why don't we go check on your brothers? Mom will be angry if she sees they made a mess."

"Okay," Himawari nodded enthusiastically.

And just as expected, the backyard was chaos. Broken clothesline. Laundry everywhere. Grass torn up from chakra blasts. Boruto and Kawaki stood a few feet apart, breathing hard, glaring at each other like neither was ready to admit defeat. Boruto wiped sweat from his brow, still grinning.

"Worth it."

Kawaki cracked his knuckles. "Say that again."

"Boruto! Kawaki!"

Naruto's voice cut through the air like a thunderclap. Both boys froze. Naruto stood in the doorway, wooden spoon still in hand, apron splattered with tiny spots of curry. His smile was gone, replaced with a tired, disappointed look. Himawari peeked out from behind him.

"I just asked you two to hang up laundry."

Boruto looked away. Kawaki clicked his tongue.

Himawari stepped forward, hands on her hips, glaring. "You scared the carrots."

Naruto blinked. "The what?"

"I almost dropped them," she clarified.

Boruto winced. "Sorry, Hima."

Naruto walked over and picked up the fallen shirt, dusting it off. "You guys okay?"

"...Yeah," Boruto muttered.

Kawaki nodded once. "Yeah."

Naruto looked between them, then handed Boruto the shirt.

"Well now that you guys are done fighting, you gotta redo it. Both of you. And fix the yard while you're at it unless you want to be grounded."

Kawaki grimaced. "Sorry."

Naruto exhaled. "If mom saw what you did here she'll be sad. The yard looks like a training ground."

He picked up the fallen laundry basket and handed it back to them. "Start with the clothes. And no chakra."

Boruto and Kawaki exchanged a look.

"...Truce?" Boruto muttered.

Kawaki sighed. "...Truce."

As they began rehanging the laundry, carefully and quietly this time, Himawari leaned against the doorframe, still shaking her head.

"I can't believe you're all ninjas," she said. "And this is how you behave."

Boruto huffed.

Hinata slid the front door open with practiced care, easing it shut behind her so it wouldn't echo through the house.

"I'm home," she called softly.

No reply came. She paused, listening. There was no arguing from the living room, no hurried footsteps, no crash followed by a too-quick "We're fine!" The house was quiet. Hinata slipped off her shoes and came to a stop. They were lined up—all of them. Boruto's sandals were neatly placed by the wall. Himawari's tiny shoes sat side by side, ribbons straight. Even the extra pair Naruto usually kicked off without thinking was set properly. Her brows lifted slightly.

She stepped inside, eyes scanning the living room. The low table was wiped down, cushions arranged, cards and game consoles nowhere in sight. Moonlight streamed through the windows unobstructed, illuminating polished floors that reflected it faintly.

Her gaze moved to an open window, and from outside came the soft rustle of fabric, rhythmic and soothing. Laundry was hanging neatly. Hinata's steps slowed as she moved toward the kitchen, her senses filling with warmth, the rich smell of curry simmering on the stove. Naruto turned at the sound of her footsteps.

"Oh! You're back," he said, grinning as if this were perfectly normal. "Welcome home."

Hinata paused, momentarily caught off guard. He stood by the stove with his sleeves rolled up, the flame already turned off, the faint scent of curry lingering warmly in the air. He must have timed dinner, knowing she’d be home by now.

"You look beautiful," Naruto added, fondly.

Hinata blushed, caught off guard by the sudden compliment. Her hand instinctively reached her hair, and she realized that she had just shown up home with a new haircut.

"Oh!" She exclaimed. "Do you like it?"

"I love it. It suits you."

"Thank you," Hinata smiled then glanced past him toward the hallway. "Where are the kids?"

"Asleep," he answered easily. "All three of them."

Her eyes widened just a fraction. "Already?"

"They tired themselves out playing all day ya know?" Naruto chuckled sheepishly, rubbing the back of his neck. "After dinner they watched a movie upstairs and when I came to check on them they were already out cold."

Hinata felt something warm settle in her chest. Naruto stepped aside and gestured toward the dining table.

"Dinner's ready. I waited for you."

She moved slowly, half-expecting the moment to dissolve if she moved too quickly. The table was set properly with the rice steaming, curry ladled neatly, side dishes arranged with quiet care. Even the utensils were aligned. He approached her and pressed a gentle kiss to her lips, brief but full of quiet affection. Hinata returned it instinctively before taking her seat, though a faint sense of suspicion lingered beneath her calm. Naruto took the seat across from her, resting his chin on his hand, watching her like this, calm, present, and content.

"...Did something happen today?" she asked softly.

He shook his head. "Nope. Just thought you deserved a break."

"Naruto..." Hinata said carefully.

"Yeah?"

She shook her head. "I love you. You didn't have to do all this," she said quietly.

Naruto smiled, gentle and sure. "Of course I had to, I'm your husband, this is the least I could do for you. And I love you too. How was your day? Did you have fun?"

Her lips curved into a small, tender smile. "I did! It was so nice and relaxing catching up with the girls. The hot spring we went to was so beautiful and served delicious food as well. We should go out on a date together someday..."

Naruto nodded immediately. "How does tomorrow sound? I'll ask Iruka-sensei to look after the kids."

"Isn't he busy?" Hinata asked. "Leaving the kids with him won't be a problem, will it?"

"Nah, don't worry about it. Besides, he misses them. He'd love to spend time with them again."

"Alright then," She picked up her chopsticks, the faint clink echoing in the calm, and took her first bite. 

"I miss spending time alone with my wife too ya know," Naruto said with a small grin. 

Warmth spread through her, easing the tension she hadn't realized she was carrying. For tonight, the Uzumaki household rested with the children asleep, dinner waiting, and the world held at bay just a little longer. Hinata met Naruto's eyes across the table and felt deeply, unmistakably at home.

Kawaki jolted awake with a sharp inhale, his body coiled tight as if bracing for impact. For a split second, instinct took over.  His heart was pounding, muscles tense, mind clawing its way out of a half-remembered nightmare. But then reality settled in, slow and warm, wrapping around him just as surely as the bodies pinning him down. He blinked up at the ceiling, the faint glow of moonlight slipping through the curtains, and let out a quiet breath he hadn't realized he'd been holding. He was in the Uzumaki house.

Buried beneath a mess of limbs and blankets, Kawaki found himself completely trapped. Boruto had him in a shameless death grip, one arm thrown across Kawaki's torso as if he might vanish in the night. To make matters worse, the idiot was drooling, a dark, damp patch soaking steadily into Kawaki's shirt. Disgusting. Absolutely disgusting. Kawaki grimaced but didn't bother shoving him off, partly because Boruto was stronger in his sleep than he had any right to be, and partly because Himawari was curled up on Kawaki's chest, warm and light, her small hands fisted into his shirt as she slept peacefully. So he stayed still.

Carefully, Kawaki adjusted his breathing, letting the steady rise and fall of the room ground him. The faint hum of the night filled the silence, the soft whirr of a fan, the distant chirping of insects outside, the quiet safety of a house that didn't creak with danger. Slowly, the tension drained from his body. His clenched fists relaxed and his shoulders sank into the mattress. Being stuck like this, smothered and uncomfortable, should have irritated him. And maybe part of him still grumbled about it. But another part, quieter and harder to name, felt something dangerously close to calm.

Everything had changed so fast. Not long ago, his life had been nothing but survival. His daily life filled with running, fighting, and enduring. Trust had been a liability. Kindness had come with strings attached, if it came at all. And now here he was, tangled up in the middle of a family that had taken him in without hesitation, without asking him to prove he was worth it. For better or worse, he didn't know which yet. But he knew this much: right now, these people mattered.

Kawaki's jaw tightened slightly. He would protect the people in this house. He would protect the people who had opened their doors to him when he'd shut himself off from the rest of the world. Whatever came next, whatever darkness followed him here, it would have to go through him first.

Boruto shifted in his sleep, tightening his grip, mumbling something incoherent. Kawaki clicked his tongue silently. Boruto was a pain. A total idiot half the time. He's annoying, loud, and unbearably geeky. A pain in the ass, sure, but a tolerable one. Kawaki would never say it out loud, not even under threat, but there were moments more than he liked to admit, when Boruto amused him.

The kid had an infuriating habit of pulling off the impossible, of charging forward with reckless confidence and somehow landing on his feet. Every now and then, Boruto left him impressed, whether Kawaki liked it or not. That thought lingered, then an idea began to form. Carefully, Kawaki shifted just enough to free one hand. He nudged Boruto's shoulder with two fingers, gentle enough not to wake Himawari.

"Boruto," Kawaki whispered, his voice low. "Hey. Wake up. I gotta ask you something."

Boruto groaned, face scrunching in irritation. "'Shaddup... stupid," he mumbled, voice thick with sleep. "'M sleepin'..."

Kawaki frowned and gave him one last, slightly firmer shove. "Boruto. Teach me that jutsu."

Silence. Then Boruto let out a quiet giggle, eyes still closed. 

"... Wha's in it fuh me?" he muttered groggily.

Kawaki paused, considering. His expression turned serious, so serious it would've been funny if anyone else were awake to see it.

"...Next time Kakashi-sensei visits," he said slowly, "we prank him."

Boruto's eyes snapped open. He lifted his head just enough to look at Kawaki's face, searching for any hint of a joke. Finding none, only that same serious and unwavering expression, Boruto grinned. He bit back a laugh, shoulders shaking as he raised a fist. Kawaki bumped his own against it. Their knuckles bumped softly in the dark.

"Ya got yourself a deal," Boruto whispered, grin still wide.

Kawaki leaned back against the pillow, trapped beneath the warmth and weight of the Uzumaki siblings, a faint smirk tugging at the corner of his mouth. Maybe this strange new life wasn't so bad after all.

Notes:
