Bakugo Katsuki is a man of few fears. He always jumps headfirst into danger with a ferocious smile on his face and thats one of the things that Izuku loves about him. He always seemed ready to face anything that came at him.

Until one day, he wasn’t.

PH!BakuDeku , (kinda) crackfic

Izuku and Katsuki come face to face with a problem that for once, Katsuki is not equipped to handle.

or

Izuku finds out that Katsuki is absolutely terrified of mice.

( pls don’t reply , qrt only thx <3 )

The front door opens widely and Izuku turns to watch as his boyfriend comes in and tosses his bags at the foot of the couch.

“I’m home,” Katsuki grumbles.

Izuku smiles and turns back to his laptop. “welcome back, ready for my list of chores for you?”

Katsuki groans, but collapses onto the couch next to his green haired boyfriend. “Lay ‘em on me,” he says with no particular enthusiasm.

“Alright,” Izuku settles in closer and opens up a doc that he’d been writing in. “First on the list is the bathroom. Plumbing’s been sounding pretty weird and-“

“-hold on. You want me to fix the fucking /plumbing/?”

“Kacchan, last week you literally had me start an herb garden on the apartment balcony. I’ve been watering your plants for the last seven days.”

“Okay whatever. Keep going.”

“Second, you’re taking over the herb garden.”

“Fine, but you’ve got that shit next week again.”

“Okay, and third, our bed is still missing two pegs from that one night. Can you please please /pretty/ please go replace the bed set and get us a new headboard?”

“A whole new bed set ? And you want me to fucking put it together on my own?”

“Just the frame and box spring! -

- /Please/ Kacchan, I’m going crazy, sleeping upright every night. It’s almost like I’m standing.”

“Doesn’t bother me.”

“Well you’re a little psychotic Kacchan.”

Katsuki eyes him for a second, giving him a disapproving look.

“Kacchan /please/, I have no doubt in my mind that you’ll be able to do it.”

“I know I can do it, Deku, I just don’t fucking want to.”

“Look I’ll help you put it together, okay? I just need that bed fixed before I go crazy.”

“How ‘bout I just put the pegs back on? Easy-peasy.”

Izuku chuckles and rolls his eyes, “Why, so we can break them off for a third time? Besides, the headboard’s all scorched and scratched, and we definitely need that replaced.”

“Fine,” Katsuki growls, “what else?”

With a bright smile Izuku goes back to his list. “Okay I think you’ve noticed the gas problem with the stove right? It keeps turning on randomly and-“

“-Yeah, I’ll fix that in a few days.”

Izuku beams up at him and lowers his laptop screen.

“That’s everything then, aside from just the normal household chores.”

Katsuki nods and pulls Izuku towards him for a quick, chaste kiss on the forehead , “Alright,” he says, hoisting himself up off the couch. “I’m gonna take a shower and I’ll get started on the bathroom.”

As he makes a move to leave, Izuku remembers another thing to add to the list. “Oh Kacchan!” he calls , just before the blonde makes it to the bathroom.

“I found some droppings in the office. Evidence points toward it being a mouse. Think you could take care of it?”

Katsuki freezes in his tracks, hand poised on the bathroom door. “A mouse?” He repeats, voice wavering uncharacteristically.

“Yeah,” Izuku continues, oblivious to Katsuki’s change in behavior, “hopefully it’s just one, I haven’t seen it yet but i don’t want it chewing on any wires or making a mess anywhere.”

He takes a second to check his watch and his eyes widen at the time displayed.

“Crap,” he yelps, getting up and tossing his laptop on the couch. “My shift starts soon so I’ve gotta head to the agency. But I’ll be back by dinner?” He says hopefully.

Katsuki nods silently as Izuku passes , receiving a soft kiss on the cheek that helps ease his nerves a little.

And Izuku leaves, grabbing his costume case and calling out a bubbly “See ya Kacchan!” waving his hand at his boyfriend who had yet to enter the bathroom.

~

When Izuku gets home, he’s tired and hungry, and /thankfully/ he can smell the telltale aroma of Katsuki’s cooking coming up the stairs. He walks in, pleasantly surprised to see Katsuki surrounded in a messy kitchen.

“Hey Kacchan.” he greets, toeing off his shoes.

Katsuki gives him a soft grunt, his normal demeanor while he cooks, so Izuku shrugs and heads into the office, dropping his costume case on the ground. As he walks to the desk, his foot just barely grazes over something small and rectangular.

It snaps from the brisk movement and Izuku, startled, stumbles backwards, slamming his hand on the desk to catch his balance. Something on the desk snaps and all Izuku feels is /pain/ coursing through his finger. He lets out a sharp cry and grips onto his wrist, -

- a mouse trap dangling from his ring and pinky fingers.

Katsuki rushes into the room and flips on the switch, dousing the room in light and revealing a startling amount of mouse traps. He stands threatened, brandishing a large frying pan, “did it get him?” He asks, wide-eyed.

“Is it dead? I heard the snap.”

Izuku lifts up his assaulted hand, and stares back at Katsuki with a look of betrayal.

“What the /hell/ Kacchan?”

“Oh.”

“/Oh/?”

“I was trying to kill the mouse.”

“Just the /one/? There’s mouse traps /everywhere/!”

“I was being efficient!”

“Efficient?? No sane mouse is coming anywhere /near/ all this!”

Katsuki’s face falls for a second, just an instant before lighting back up with realization.

“Of /course/, there’s no fucking cheese.” He turns away to leave, moving to head back into the kitchen.

“Kacchan! What about my fingers?”

“Why should I care what happens to your shitty fingers, you used to break your shit all the fuckin’ time in high school.”

“Hey-that’s different!”

“Ya, your fingers aren’t fuckin /broken/ this time, you’ll live. Hurry up, food’ll be ready soon”

~tbc~

Over the next couple days, Izuku noticed Katsuki uncharacteristically ignoring his share of his housework, and he found himself cleaning up more and more behind his boyfriend than normal.

The blonde had seemingly been on edge all week and had made no clear attempts to assure Izuku otherwise. He‘d been jumpy and fidgety and had been walking around the apartment in an apprehensive manner, eyes cautious and alert, heedful of his surroundings.

Izuku had found it hilarious.

So much so that he had started his own lil one sided game.

When Katsuki would leave the apartment, izuku would scatter fake mouse droppings in every other room, just to get the blonde agitated. He would drop crumbs of food around the apartment to make it look like the poor mouse was being more active.

And at night, he’d discretely use his quirk to make scratching noises against the wall, which he KNEW, despite Katsuki’s lack of addressing the matter, was making the blonde freak out.

So far, he was doing just enough to push Katsuki closer and closer to the edge and it was funny to watch his boyfriend jump at the slightest noise or tense from a movement he /thought/ he saw in his peripherals.

It was a blast of a few days for Izuku, and with Katsuki thoroughly (and deliberately

) ignoring the housework, he didn’t feel guilty about milking the /fuck/ out of his boyfriend’s little mouse fear.

He found small pleasures in watching Katsuki’s muted expressions when one of his pranks spooked him. And he loved it, he really did. But he found out very soon, that just teasing him wasn’t enough for Izuku.

See, Katsuki was never the type to show fear. But now that Izuku had caught a tiny glimpse of it, his mind refused to let him think of anything else until this new emotion was documented. /Thoroughly/.

So Izuku did what he needed to do to get the results he wanted to find.

He went into the cabinet and poked holes into all of Katsuki’s favorite spicy snacks.

This one, he’ll admit, went a little too far. And it definitely backfired on him. But when Katsuki found out, he was nonetheless capital p: Pissed.

“You’ve gotta be /fucking/ kidding me!” Katsuki bellows from the kitchen.

Izuku ignores him at first, but after listening to the suspicious noises of angry clattering, he trots into the kitchen to see what put the blonde in such a fit.

Katsuki was standing with the pantry doors open, angrily pulling all of their food off the shelves and into an overflowing trashbag. He was scowling as perfectly good food, even some packages /unopened/, was tossed hastily in trash.

“Kacchan, what’s going on in here?” Izuku asks warily, eyeing his boyfriend from a safe distance across the island counter.

“The fucking mouse got into our food.” Katsuki growls. He holds up a large package of his favorite spicy ramen, holes littering the top.

Holes that /Izuku/ had made and had conveniently /forgot/ about.

Oops.

“Can you believe this shit?” Katsuki angrily drops the package into the trash and swipes at their collection of boxed cereal. “Who knows what else that furry bastard could’ve gotten into.”

“You’re not throwing out /everything/, are you?” Izuku asks nervously.

Katsuki scowls at him. “You wanna be sharing our food w Stuart Little here?” He shakes his head in disgust. “Course I’m throwing out everything. It’s all fucking contaminated.”

Izuku gives him an uncertain look and Katsuki just rolls his eyes.

“Shit, you wanna invite the damn thing to dinner? Since you’re so privy to letting it eat us out of house and home?”

“But Kacchan, all this is gonna be expensive to replace, and-”

Katsuki reaches for a familiar looking box toward the back of the pantry and Izuku suddenly /panics/.

“Wait!” He shouts, aiming a 0.3% Air Force smash towards Katsuki’s outstretched fingers.

It wasn’t too strong, just enough to knock Katsuki’s hand away.

“Deku, what the-“

“Not my All Mighty-O’s!” He shouts protectively, despite being on the other side of the counter.

“All Mighty- Deku are you /fucking/ kidding me?!”

“Don’t yell at me!”

“Give me one good reason not to!”

“Because you’ll use your quirk and we need to mindful of the gas in here!”

Katsuki sighs in frustration and gingerly pulls the box off the shelf. “Deku- just /please/ fucking tell me that this is not the Limited Edition Silver Age All Might: Hero’s Tribute Mighty-O’s ™ that came out /four/ years ago?”

Izuku keeps quiet but nods shyly “It might be.”

“This is going in the trash.”

“Kacchan! You can’t!”

“Why not? It’s stale and expired!”

“It’s Limited Edition!”

“It’s fucking /cereal/!”

“Kacchan, do you realize that this could be the /last/ piece of official All Might merch that’ll ever be released? It’s a /tribute/ Kacchan! That word is so /final/! You can’t tell me it doesn’t scare you!”

“It doesn’t Deku! Why do we need his merch when you chose an apartment right down the fucking street from him! You don’t need to idolize the guy, I mean shit, you have me cook dinner for him every other week!”

“But Kacchan-“

“/Trash/.” Katsuki emphasizes with his no nonsense tone. He stuffs the cereal into the trash bag, making sure to damage the box just enough so Deku wouldn’t come scavenging.

Izuku lets out a dramatic sigh and retreats to the room to go pout.

He doesn’t speak to Katsuki for the remainder of the day, leaving the blonde to continue cleaning out their infested food and rant to himself about how much he fucking hates mice.

And that night, while the boys laid on their lopsided bed (that katsuki had not yet got around to fixing) Izuku could hear something akin to actual scratching in the walls.

He sighs and turns over to face Katsuki, lamenting the fact that he has to sleep at a 25° degree angle AND listen to this stupid mouse run around inside their walls.

He snuggles close to his boyfriend, knowing that the noises would likely keep the blonde awake and worrying.

Briefly, he feels a bit guilty about keeping Katsuki up the previous nights with his own scratching antics but then he remembers that Katsuki’s fear isn’t rational enough for him to condone the neglect of his /bi/weekly chores.

Plus the asshole threw his rare All Might cereal away with /zero/ sympathy.

Jerk.

A slight sniffle escapes him and he changes his mind about the snuggles, letting go and turning over again to face the wall instead.

Stupid Kacchan doesn’t deserve any snuggles tonight.

~

A few days later, when Izuku comes home from work, he’s disappointed (but not surprised) to hear the continuous banging in the walls after using the bathroom.

“Kacchan,” he calls into their room, “you haven’t fixed the plumbing yet?”

Katsuki emerges with a plethora of new traps and baits in his arms. “It’s not the plumbing,” he says casually, “it’s the mouse.”

“What?”

“There /is/ no plumbing, it’s just the mouse.”

“Kacchan what are you talking about?”

“/Fuck/, Deku.” Katsuki growls, dropping the load of traps to the ground in the hallway. “Those sounds you’re hearing, it’s not the fucking plumbing. It’s the fucking /mouse/.”

“...The mouse...”

Katsuki waves his hands encouragingly, trying to coax Izuku into catching on. “...In the...pipes.”

Izuku raises his eyebrows, surprised, “...In the pipes,” he repeats skeptically.

He frowns, a bit concerned. “The mouse is in the pipes...”

After thinking about it for a second, the corners of his lips curl into a smile, “Like that old movie... ‘Flushed Away?’” He asks w a slight giggle.

“Don’t you fucking patronize me.”

A sudden noise begins to sound in the wall and Katsuki crouches, instincts on alert mode. “Listen!” He hisses as the light banging noises sound over his voice. “That doesn’t sound like a mouse to you?”

...

“...No Kacchan, it sounds like the plumbing.”

Izuku moves inside the bathroom and turns the faucet on then off. The banging noise starts up again and Izuku gives Katsuki a pointed look. “Plumbing.” He reaffirms.

“It could /totally/ be—“

“—/Regardless/ of whether or not there’s a mouse in the pipes, I can still hear banging and clanging in the walls. /Additionally/, our bed is still lopsided and the kitchen still smells like gas.“

“Half the week has gone by, and I’m /still/ watering your herb garden! What have you been doing, Kacchan?”

“Trying to get rid of this /fucking/ mouse !!”

“...You totally owe me for this.”

“I do fucking /not/. I’m /exhausting/ myself tryna get rid of the lil motherfucker. It’s hard fucking work.”

“Three mousetraps, Kacchan.” He says, voice sounding a lil unhinged. “Three /freaking/ mousetraps.” He holds up three fingers, emphatically raising one with each pointed word.

“I’ve stepped in THREE! I’m about to stop taking off my shoes when I get home and then start making YOU mop up all the dirt I track in! This is RIDICULOUS!”

“HOW DO YOU THINK I FEEL?!?! YOU JUST WANT TO MAKE MORE WORK FOR ME!”

“HUUUUH??? HOW DOES THAT EVEN MAKE SENSE?! I’M THE ONE THATS BEEN CLEANING UP AFTER /YOU/!”

“WHA-“

Izuku turns and jabs an angry finger in Katsuki’s face. “Don’t even /think/ about saying it’s not true.” he says, voice low and dangerous. “Who did the laundry this week? Me, Kacchan, it was me. Who mopped the floors? Also me, Kacchan. Who cleaned the bathroom? I did, Kacchan.“

“Oh and like I said, I’ve /also/ been watering your /stupid/ herb garden /every/ freaking morning! While you dance around the apartment, scared of a freaking /mouse/!”

“I’M NOT FUCKING SCARED OF-“

“KACCHAN!”

“WHAT?!”

“THE /MOUSE/ ISNT THE FREAKING POINT.”

Katsuki blinks, barely realizing that Izuku’s voice was laden with pain and frustration. Tears were pooling in his green eyes and his fists were balled up tight.

“You threw away my rare All Might cereal.” Izuku says with a whimper.

“IS THAT WHAT THIS IS ABOUT?”

“NO. ITS NOT BUT I FEEL ITS A TOPIC THAT SERIOUSLY NEEDS TO BE ADDRESSED.”

“Deku, it’s fucking /CEREAL/.”

“It was /important/ to me!” He sniffles. “You crossed a line, Kacchan. You really did.”

Katsuki scoffs and rolls his eyes. “Whatever. The only reason that box is /rare/ is because it’s ages old and yours is probably the only one left that hasn’t been eaten yet.

“Exactly!”

“Shut /up/ Nerd, I’m not fucking sympathizing with you!”

Izuku huffs. “Look, Kacchan, I’ll ignore the cereal for now, but you’re actually driving me nuts. /Please/ let’s just get back on schedule, and get everything fixed so our lives can go back to normal, /please/. The bed? I would /really/ enjoy sleeping laying down, yanno?“

He sighs dramatically. “And for the love of Kami /please/ just call the gas company or something. I /need/ to eat something homemade. We can’t just avoid the stove because of the gas.”

Katsuki rolls his eyes but continues to let the nerd rant. “Yeah yeah,” he says when Izuku stops talking. “I’ll fix the plumbing right now.”

And for the next half hour, Katsuki kept himself locked in the bathroom, and Izuku was left to listen to mysterious grunting and angry curses. Intrigued, he stationed himself outside of the bathroom, curious as to how his boyfriend would emerge from this endeavor.

Sure enough, thirty minutes later, the bathroom door opens wide to reveal a sopping wet and seething Katsuki.

But when Katsuki gets a look at Izuku’s cute little inquisitive expression, he feels the tension drain out of him. “I’ll call a plumber,” he says, tired and defeated.

Izuku gives him a sad look, and he did look miserable, standing in the nearly /flooded/ bathroom, drenched with water.

But Izuku was also miserable. And he was still mad about his cereal.

He moves his line of sight past Katsuki and widens his eyes to look surprised. He points (with a rehearsed finger) and /screeches/.

“THE MOUSE!”

Katsuki’s expression was straight /gold/.

The blonde whips around fiercely, eyes harboring that intense panic, and hands already poised to attack. But his swift (and miscalculated) action has him slipping on the water beneath him and he topples to the floor in a flurry of arms and legs and angry curses.

Izuku sputters at the sight of the normally ‘composed’ hero flailing around in the water of their messed up bathroom and he leans over, heaving in laughter as Katsuki tries (and fails) to get up and away from the imaginary mouse.

“DEKU!” Katsuki screams, backing himself up into a corner and defensively aiming his outstretched palms toward absolutely nothing, “WHERE IS IT?!”

The words do nothing but encourage Izuku’s side-splitting laughter, and he clenches his stomach at the hilarity of the situation.

“THE FUCK ARE YOU LAUGHING FOR? WHERE’S THE FUCKING MOUSE?!”

Izuku cackles, tears springing to his eyes. His cheeks and stomach were /aching/ and he attempts to get some words out but the sight of an angry Kacchan, dripping wet and /terrified/ is too much for him and he doubles over, gasping for breath.

“I can’t /breathe/,” he wheezes, squeezing his eyes shut and slapping at his thighs to expel the leftover chortles.

It takes Katsuki about three seconds to figure out what’s going on, and needless to say, he is /not/ amused.

“YOU SHITTY FUCKING ASSHOLE /BASTARD/!” Katsuki bellows, rising to his feet in one precise movement.

And just like that, Izuku’s fit of laughter is immediately cured.

He shrieks in genuine fear and bolts into the living room, ducking behind their couch.

But Katsuki is after him with a vengeance and their chase propels them into the kitchen, with Katsuki standing menacingly across the island counter and Izuku waving his hands placatingly.

“Wait! Kacchan! /Wait/! You can’t use your quirk on me!”

“Give me one reason why I FUCKING SHOULDN’T!”

“The GAS, KACCHAN! We’ll both /explode/!”

“Well /you/ deserve it and I’M FUCKING FIREPROOF SO LETS FUCKING GO!”

“KACCHAN NO!”

Izuku manages to escape the kitchen before his boyfriend can wreak bloody havoc and he finds himself hiding in their room with the door locked tight and double checked.

“Deku, if you don’t get your ass out here right the FUCK now, I’m gonna-“

“-You really are scared of mice aren’t you Kacchan!” Izuku taunts from behind the safety of his door.

Katsuki slams an angry fist on the other side, making the door creak dangerously. “I’m gonna fucking /rip/your lungs out, DEKU! Come THE FUCK out!”

“Why, Kacchan? You don’t wanna be out there all alone with the mouse?”

He expects another angry retort but a dry silence is the only answer he receives.

“Kacchan?” he calls, confused.

When he still gets no answer, he cautiously, and against his better judgement, opens the door to peek outside.

Katsuki is sitting there, back up against the wall, face buried in his arms, and a suspicious sniffling noise coming from his nose.

It’s a sight to behold.

“Kacchan?” Izuku asks softly, previous frustrations already forgotten.

Katsuki doesn’t move but a small voice speaks quietly and if Izuku didn’t know better, he’d never assume it came from his explosive blonde.

“Don’t fucking /do/ that shit.”

The voice is a low whisper and it doesn’t take much for it to wrench Izuku’s heartstrings in every direction.

“Sorry,” he whispers back, sliding down the wall to sit next to his /sniffling/, (because he’d get his ass kicked if he ever assumed Katsuki was crying) boyfriend.

He places his hand in spiky blonde hair and scratches soothingly at Katsuki’s scalp. “I was still mad about my All Mighty-O’s.” He explains.

“Deku shut /up/ about your stupid fucking cereal.

Izuku chuckles. “Sorry Kacchan.” After a thick silence he smirks and speaks again. “But you have to admit, that was downright /hilarious/.”

Katsuki side-eyes him with a narrowed brow but relents and shoots him a flustered grin. “I fucking hate you,” he says, shaking his head.

And just like that, almost all is well between them.

When night arrives, the boys lay down diligently on their awfully angled bed. They’re both plagued by the built up emotions of the week and the mouse’s relentless scratching in the walls does nothing to calm either of them.

Though still feeling a bit guilty, Izuku pulls his boyfriend close and snuggles him tightly. And the action is just enough to mute the terrible noises and stave off the blonde’s niggling fears.
