"I'm home!" Izuku calls as he hops over the mess of shoes just inside of the genkan.

The girls have taken to trying to escape the apartment lately (though they were far far /far/ too short to reach the handle, let alone the lock),

but they always ended up getting distracted by playing with the shoelaces instead.

Still, Katsuki had ordered a shoe rack that they could hang on the wall to stop both the knotted laces and the tripping incidents. One time Izuku had come in after a long day

and nearly faceplanted directly onto one of the twins… he probably lost ten years off his lifespan that day.

No one returns his call with a 'Welcome home,' so Izuku just quietly takes off his shoes and his jacket with a fond shake of his head. Katsuki might be taking a nap,

then, after being left so long with their daughters.

The two bags Izuku has hooked over one elbow (of snacks and extra baby formula) crinkle softly in the quiet.

The house feels too big with the absence of childish giggles or either one of their exasperated, fond laughs at the baby-antics, but he wouldn't look a gift-horse in the mouth.

Quiet just meant that they weren't crying or throwing a fit, after all.

So Izuku totes the few items he bought to the kitchen. He puts them away quick, so that he won't forget to later. Kacchan always did like having a neat home.

The empty bag gets left on the island, though,

and Izuku scribbles out a quick note on the fridge's whiteboard to finally figure out the recycling system of their new place.

They'd only moved in about a month ago, and Izuku kept forgetting about it. He's almost surprised Kacchan himself hasn't done it instead,

especially when they have a few leftover moving boxes to toss out, but… the kids were admittedly hard work.

And Izuku'd never blame him for it anyway! Kacchan deserves as many breaks as he wants.

Izuku hums to himself, quickly getting lost in the thoughts of taking Katsuki on a vacation and imagining how cute a family photo would be of them all at the beach in matching swimsuits and sun hats. Maybe something with flowers?

He puts a pot on to boil water as he muses.

If the twins hadn't eaten yet, he'd use it to heat their bottles before they got put to bed for the night. And if they /have/, then he'll just use it for a quick bowl of ramen and take an early night with Kacchan

instead of staying up late to fix something before immediately going to sleep.

Hm… has Kacchan eaten yet?

Izuku mutters to himself as he covers the pot that was already hot to the touch. He leaves the kitchen, peeking into the living room for the first time,

to see if his family was hiding somewhere in the couch cushions.

But nope, a cursory glance shows no one sitting on the couch, and the bedrooms are just as empty.

Although, the bathroom told him that Katsuki had filled the tub only a little bit ago by the way the water inside of it was still warm and fresh.

Izuku patters back to the living room and, for some reason, checks the linen closet. It's so stuffed full

that he nearly gets trampled by the avalanche of futons and comforters that attack him in his absent-mindedness.

Atleast he knows no one is hiding in there, though.

As he puts the closet back in the right order (because Kacchan /will/ kill him if Izuku gets back into the habit of just stuffing unfolded blankets into whatever nook they fit in the closet), he glances back at the small mess in the living room.

There's a few baby blankets on the floor, meant to protect the girls hands and knees from the hardwood (or to cushion their fall when they get too excited and faceplanted when grabbing a toy or their father's hands to get their attention).

Atop the blankets are a few toiletries;

baby powder and lotion, scentless wipes (because Mizuki's skin was sensitive to the other kind, though Tsukari's strangely was not), and a few elastics for their hair.

Kacchan must have given them baths while Izuku was gone, then.

But no sign of them there anymore.

Maybe they went for a walk?

Izuku shambles back to the kitchen to turn the heat on the stove down low, just in case they'd be back long after he was done. Kacchan /did/ like taking the girls on walks every two days or so,

just so that they wouldn't be 'hermits' (according to Kacchan).

And even though they'd gone out earlier as a family to the mailbox and the front office just so that the girls got some fresh air, Izuku /had/ been gone for about an hour.

So maybe Katsuki went with the twins for a walk around the park to tire them out?

Izuku has just pulled out his phone to call his husband when, out of the corner of his eye, he sees the balcony door cracked open just an inch or two.

The curtains are drawn, but he can see how they lightly billow with the breeze coming through the crack.

If he listens close, he can hear the familiar babble of his babies and the low-timbre of Kacchan's responding quips.

Izuku is already beaming,

face split with the magnitude of his smile, as he skips over and slides the door open wider.

"Kacchan!"

Katsuki doesn't startle at his husband's sudden appearance, probably because he already heard Izuku running in and out of the various rooms in the house.

But Tsukari does let out a sharp noise that could maybe be considered a yell.

She immediately lunges towards Izuku, mouth opening and closing as she fusses at him a mile a minute in her own baby-language.

Once she reaches him, she chews on his pants leg, trying to eat him whole for daring to surprise her.

Katsuki is sitting on the ground, leaning against the balcony railing. It's solid and thick so as to prevent anyone slipping through,

but also so that they wouldn't have to worry about nosy neighbors interested in Japan's top heroes.

In between his legs sits Mizuki, half swaddled in her favorite blanket. It's too big for her, but she loves it so much (and looks so cute in the baby blue

decorated with pink and yellow clouds!) that they just let it be.

She's teething on a squishy toy and slobbering all over the small, soft terrycloth that Katsuki has hooked over one shoulder just for that reason.

"Hey, Deku," Katsuki greets as Izuku leans down to pick Tsukari up and blow raspberries against her chubby chin.

She giggles and stops trying to chew on him in response, and he gives her a proper kiss on her cheek as Izuku knees to sit down beside Katsuki.

Katsuki shifts so that Mizuki can balance and rest against one knee.

Once he's sure that she's in no danger of falling, caught between his curved arm and the firm planes of his belly, he turns fully to usher Izuku closer.

"Welcome home."

"I'm home," Izuku says again, soft and quiet and loving.

He scooches closer as demanded, and Katsuki finishes the greeting by pressing their foreheads together and kissing first his top lip, then his bottom lip, and then both.

A silly little tradition he'd adopted after they'd gotten engaged— and one that Izuku absolutely adored.

He's still weak for it even after all this time, and he sighs dreamily as Katsuki leans back over properly to rock Mizuki as she gets fussy.

"Did you three have fun, Kacchan?"

"They were little terrors," Katsuki says, proudly. "Woulda scared off a villain or two all by themselves."

"Mm, I'm sure Kacchan would've stopped the villain before they even had to," Izuku teases, mostly to Mizuki nestled in his arms.

Not that Izuku wouldn't do the same of course, hypothetically or otherwise.

He'd never known how fiercely protective (and possessive!) he could get when it came to kids. Although, he probably should have gotten an inkling when he met Kota… and Eri… and Katsuma and Mahoro.

"Damn fuckin' right," Katsuki grumbles. "As if I'd let some second-rate asshole fuck with my girls."

He bounces his knee, and Mizuki blinks tiredly at Izuku as she leans forward to rest against her papa's chest. Katsuki supports her back as she does,

almost absent-minded in the way that he moves the towel so that she doesn't cover her face in her own slobber.

Then he smooths down the soft, full head of hair that peeks out past her little baby beanie that's pulled down low to keep her ears warm.

(Mizuki's own is in the corner of the balcony, probably pulled off by her own stubborn fingers.)

The hair springs back up despite the grooming, pale blonde exactly like Kacchan's own. She almost looks like an exact copy of him, actually,

all the way down to the red eyes and the fierce look she gets in them when she's upset.

Luckily, she's only sleepy and happy most of the time. She's a rare crier, and even then she's oddly /quiet/ when she does so (unless she's hungry).

Rather, she prefers to quietly watch whatever is going on from the comfort of her baby sling, or from one of her papa's hips, instead of being in the middle of it herself.

Tsukari, on the other hand, loved to be the center of attention.

She loved making noise and watching people's reactions to the noise, and the messes she makes. Maybe she's also like Katsuki, in that regard. And of course, she looks exactly like him, too.

The only thing of Izuku's that either of the girls got, in fact, were the few freckles here and there on their soft, chubby faces, along with the way their hair curled up as it grew longer and longer with the months they grew.

"You're gonna make their first word be a swear," Izuku gripes. "Everyone would have a heart attack."

"Fuck 'em."

Izuku can just /imagine/ how their parents would react. Even Katsuki's mom would yell at them for letting it happen (oh geez, not to mention how quickly his own mom would probably pass out hearing a babyish 'Fuck!' pop out past his twins lips).

But Izuku can't find it in him to be too upset, because he knew how happy he would be just to know that his girls were speaking their first words at all.

… Maybe he was just too used to Kacchan.

Ah, well. Izuku wouldn't want it to be any other way than by Kacchan's side.

Izuku leans over, resting his head against Katsuki's free shoulder.

Wind passes over their heads, but there's no chill that follows thanks to the balcony's high walls. As such, Izuku is perfectly content to stay there and bask in the presence of his family

for as long as he's able. For the rest of his life, if he has anything to say about it.

Tsukari grabs for the necklace peeking out from beneath Izuku's collar. It's his wedding ring, kept safely tucked away so that he doesn't lose it while he's on the job.

Plus, rings /hurt/ when you punch someone while wearing one. They both should know that by now.

Katsuki has a matching one, though his chain is gold instead and, thus, almost blends in with his sun-kissed skin.

Izuku remembers the first time that Katsuki had melted through his wedding ring on the job. It'd taken just one explosion— not even his max power.

The only reason he'd even known it was his Quirk was because of the burn mark left behind from molten metal being seared off of his skin. Luckily it didn't do any lasting damage, beyond messing up his gauntlets.

And though it had been /very/ cool to learn after the fact,

it had been heartbreaking for Katsuki to realize after the heat of the moment was over.

After all, he'd never get back that same ring that Izuku had slid on his finger right before they kissed for the first time as /husbands/ at the altar.

Izuku was more than happy to mimic the scene when he bought a new one, and even went as far as to buy a second one matching his first, just so that they would still have matching sets.

It was technically a frivolous spend, and Izuku didn't really /need/ two rings (though the first is safely hidden, framed beneath their wedding photo on the wall in their bedroom), but Izuku could tell that it comforted Katsuki in its own way.

So, yeah. Necklace rings for the both of them.

Tsukari grips the chain mightily in her tiny fist, jangling it to hear how the ring rattles against the silver chain.

Her eyes go wide and sparkling with interest each time she makes a successful noise, as if she doesn't do this almost everyday.

Izuku doesn't much mind how she's basically choking him out with the tight grip, instead encouraging her by helping move the chain.

"Yeah? Are you gonna be a musician when you grow up, little love? Should we let you stay with Jirou-chan sometime?"

"And have her blow out her eardrums? Hell no."

"Kacchan, she's heard you yell probably even before she was born. And you're /much/ louder than Jirou-chan."

Katsuki doesn't really have anything to argue with against those teasing jabs,

so he just leans back with a 'tch', and turns his head away. Tsukari lets go of Izuku's necklace, almost in response.

She kicks her legs out, making little grunting noises as she opens and closes her hands—

as if she was big enough to grab Katsuki and hold him close instead of vice-versa.

Izuku lets her climb from his arms and slide into her papa's lap instead.

It's a tight fit with Mizuki lightly dozing on his other thigh, but she sidles up quickly in the free space against his chest.

She lets out a triumphant, "Bah!" and begins to giggle wildly when Izuku can't help but hold a hand over his heart and sigh, lovestruck.

"Guess I'm just a jungle gym now. Great." Katsuki slides down a few inches, until he's nearly flat against the ground. "Number 2 Hero, demoted to a piece of playground equipment."

Izuku outright laughs at that, fitting his knees beneath himself so that he can lean forward enough to press a kiss directly against Katsuki's lips.

"You're a very handsome piece of jungle gym?" Izuku tries. When that just makes Katsuki glare at him, Izuku pulls back with a laugh and amends, "And a handsome hero!"

"Thanks," Katsuki says, deadpan as roadkill.

Then, there's a sharp whistle sounding from the kitchen. The pot of water, boiling and screaming as it escapes from beneath the tight lid.

"Ah!" Izuku hops up like a startled deer. "Hurry inside, Kacchan! Let's feed the girls and put them to bed.

Have you eaten? I was going to make ramen."

As if overcome by the spirit of a tornado, Izuku runs around the balcony in a flurry.

He picks up the few toys that Katsuki and the girls had dragged out with them, stuffing each one beneath his armpit.

Then he grabs the soiled towel that lay, nearly forgotten, in the corner beneath Katsuki's back.

"Oh, and have you already taken a bath? I saw the water— we can reheat it and take one together, if you want. I didn't know how tired you were though,

which is why I was going to make ramen so that we could relax together. Did you eat?"

Izuku hops on one foot as he rambles, using his other to slide the door open further.

"You asked twice."

He's only stopped from falling over because Katsuki stands and lets him lean against his side.

The girls are tucked over each shoulder, one fast asleep and the other gripping the hem so that she can lean over and make grabby hands at the dangling wind chime above their head.

"Ah, thanks Kacchan," Izuku says, taking a breath to calm himself. "Sorry."

"'s fine. C'mere, nerd."

Izuku's soft, questioning hum gets interrupted as Katsuki steals another kiss from him.

Their lips meet and, just like before, it makes Izuku melt just as much as it did the very first time they kissed, so many years ago. His shoulder drop, entire stance relaxing.

The warmth of their home outlines the two of them as it drifts out of the open door, and Katsuki makes a soft sound that has Izuku's heartbeat strengthen beneath his rib cage.

He's only just blinked his eyes all the way closed when Katsuki pulls back,

balancing Tsukari and Mizuki more securely against his person.

When Izuku looks again, expression positively smitten, Katsuki grins mischievously down at him. "Let's get the girls to bed. Then we can go bathe and finish what you started."

Katsuki sweeps past him, hushing the girls as they shift and fuss at the change of scenery.

In the light of the living room, Izuku is able to get almost a better look at him than he was able under the waning sun.

Perhaps for the first time, Izuku actively notes how much /different/ Kacchan looks now.

Even without Izuku fully realizing it, Kacchan has gone and grown taller and larger all over after they became pro-heroes.

But still, despite his large hands and his battle-scarred skin and the imposing figure he cuts with a well placed smirk and a quirk of his brow— Kacchan is so soft.

His smile is less reserved, his shoulders less tense with the urge to prove himself to everyone with everything he does.

Fatherhood changed him in a way that Izuku can't say he expected.

He was certain Kacchan would be more firm, or atleast fumbling the same way that Izuku felt like he himself did the very first night they took Mizuki and Tsukari home.

(And still felt, sometimes. Anxieties persevere, especially in the dark of night when he's alone with himself, even in the same bed as his Kacchan.)

But, somehow, fatherhood came to him naturally and grew him into an entirely new, but entirely the /same/, Kacchan.

Of course he wasn't /perfect/ at it. Even if they had another down the line, Izuku is sure they'd learn new things every day just like they did now.

And Kacchan had his own fears, too. In those same dark nights,

he stressed as much as Izuku did about the vast multitude of their girls' futures. They were precariously held in each of their hands— but he accepted the challenge as gracefully and as powerfully as he could.

But if there was ever anyone out in the world who could do so, it was only Kacchan that could take every day's losses and change himself little by little every day, until there were only win-win-wins. As a parent, as a husband, and as a person.

Watching Kacchan in that moment, Izuku vows to himself to meet him in the middle, win for win for win.

Excitement pools and skips around his gut like a rushing river just at the thought of being able to grow into their roles as parents— together. Hand in hand.

Katsuki glances over his shoulder, and three pairs of red eyes blink curiously at Izuku as he tries to commit the scene to the deepest part of his memory. But Katsuki doesn't say anything, only balances Mizuki and holds his hand out to Izuku, as if he /knows/.

Maybe he does.

Izuku smiles bright as he goes to meet Katsuki in the middle.

"… Wait." Izuku's face goes red all at once as the implications of Katsuki's prior, teasing words hit, and he fumbles with the baby toys as he hurries past the threshold. "What /I/ started?!"

Katsuki snorts, already heading towards the kitchen.

Izuku flounders for just a brief moment, tossing the toys on the couch with an embarrassed, "Kacchan!" as he hurries after him.

The balcony door slides shut with a soft click; it keeps secure the soft, warm atmosphere of the Midoriya-Bakugo household for the rest of the night, and for the rest of forever.
