a bkdk AU where they're next door neighbors.

wait, hear me out.

they've been living next to each other for almost an entire year but have never seen how the other looks. despite that, they have still communicated thanks to their paper thin walls.

the first time they ever "speak" is the same day katsuki moves into the complex, due to his work schedule katsuki sleeps all day and works at night, which meant that on his days off the blond was up all night doing errands or cleaning around the house.

moving his things, unfortunately for him had to also be done at night.

and Izuku who was 9-5-er needed his rest! in a fit of rage, but in a very poised way, izuku leaves a little sticky note on katsuki's door after knocking and going back to his place.

katsuki was barely able to notice the door next to him slam shut.

: people are sleeping here, thanks.

the blond had to laugh at the stupid little piece of paper and crudely written note.

katsuki dug through his office supplies and found his own stack of sticky notes.

neatly writing,
: i'm moving in, asshole

and for shits and giggles, he also knocked. not caring that it was like 2 in the morning. still katsuki did try to keep his noise at a minimum.

before izuku left for work, he saw the note stuck on his door. the greenette rolled his eyes.

:who the hell decides to unpack at 2 in the morning!

izuku scribbled in a note and plastered it on his neighbors door.

: people who work overnight??

: oof that sucks. ok truce. welcome to hell~

katsuki didn’t respond after that. but he definitely got a kick out of his neighbor. as weeks went by they started to communicate again when the mail would get switched and they'd have to leave the other's mail at the door.

: looks like this is your mail, katsuki-chan. nice name. the final notice envelope looks menacing

: don't look through my shit, deku! your name is stupid. here's your mail.

: it's Izuku!

: whatever. more mail.

they had weeks were they wouldn't communicate at all. until Izuku had to stay home from work one day with a bad cold.

he had been watching a movie on his bed with a box full of tissues at his side and a bowl of soup in one of those bed trays.

the movie was a bit boring and Izuku was almost drifting to sleep when he heard a small groan.

Izuku's ears perked up a bit at the noise. it almost sounded like—

"fuck, yeah." another groan followed by the sound of a bed frame slamming against the wall.

did I mention the walls were paper thin?

katsuki's bedroom was adjacent to Izuku's. and it just so happened that apparently they decided to place their bed in similar fashion, since izuku could practically feel the vibrations through the wall.

"jesus, they were loud!" Izuku thought, trying not to blush from secondhand embarrassment.

whoever his neighbor was railing was whiney as all hell and apparently had a fetish of calling katsuki a master.

"yes, master. right there!"

"fuck me, master!"

izuku had to laugh. instead of bothering his neighbor he simply wrote a note and left it on his door.

: master? really??

Izuku didn't realize what his neighbor had said about the note bc he fell asleep, right after.

he woke up at around evening time when he heard a knock at his door.

grumbling and rubbing his eyes, izuku went to check only to see an empty hallway and a new note stuck on his door.

: mind your fucking business, deku

: my ears have been tainted!

: just jealous you ain't getting any, fucking nerd.

: I get enough, thanks.

a month passes with little to no activity. except a day when katsuki was fighting with his partner, izuku figured. there was shouting and then something slammed against the wall.

izuku was due to go to work but called out bc he was falling behind on his college homework.

maybe katsuki thought that he wasn't home bc he could hear just about everything they were yelling about.

"how could you?!" katsuki voice broke a little in the end, "I fucking —fuck I trusted you! was I not enough for you?!!"

there was unintelligible shouting as they both yelled back and forth.

"you're such an asshole! that's why I cheated on your ass." the female voice shouted.

there was a loud punch against the wall that made Izuku nearly jump from his desk chair, his homework on his desk untouched.

damn, that's rough.

there was some more back talk and shuffling until Izuku heard the front door slam shut.

izuku didn't even know him and he felt bad for him. he knew kacchan was a bit rough but he genuinely seemed like a nice guy. he even picked up his plant that he left by his front door, toppling over it one morning when he was rushing to work.

: damn, take care of your plants, loser.

Izuku hadn't even thanked him for that. he was a bit curious at what was going through kacchan's head so izuku placed his ear on the wall to see if he heard anything else.

he could hear some muttering as if he was on the phone.

"okay, bye." and the next thing he heard made Izuku's heart swell in his chest.

katsuki was sniffling. "fucking idiot" he blubbered to himself.

Izuku didn't know what came over him. the next thing he knew was that he was

gathering his baking supplies and taking out a bag of flour.

Izuku was okay at cooking but he was great at baking! his mother had recipes of classic treats with secret ingredients that made people want more. so he made Midoriya famous peanut butter and chocolate chip cookies.

he took great care in mixing and conjuring up all the ingredients, setting his oven just right and baking the cookies to perfection.

after they slightly cooled, izuku took one to taste.

a delicious explosion of pb and chocolate, just like he remembered. he hadn't baked in

a good while and Izuku forgot how much he missed it.

he packaged them carefully in Tupperware and in a discreet note he wrote:

: I made some cookies for a work thing and made too much ¬¬ thought I'd give you some for picking up my plant, thanks - izuku

izuku waited just before katsuki was due to go to work, leaving the treats on the floor and knocking; quickly going back to his apartment. he hoped that somehow it'd bring a smile to his face after what he went through.

Izuku didn't realize just how much katsuki appreciated it.

like this AU? for faster updates on this thread or others. my ko-fi is always open https://ko-fi.com/fluffyrin 

katsuki didn’t know what heaven tasted like. but if it tasted like anything, it would be these fucking cookies because damn these were the shit.

they melted in his mouth, leaving an explosion of chocolatey, peanut buttery goodness that nearly made his mouth cum.

katsuki was just about to leave and grab a quick snack before work when he heard the door and saw the container with deku's shitty writing on it.

after the crappy day he had and hardly having any sleep, this somehow made his long night ahead a little better.

he did find it strange that Izuku was giving him a thank you gift for doing something as silly as picking up a plant. but fuck it. he was thankful.

so thankful in fact that he wasn't going to let himself be one upped by deku.

he made a plan to make something for him when he go home.

for whatever reason, he somehow felt inclined to. besides the fact that he really wanted to show off his cooking skills.

the following day, Izuku was on his way out to work when he almost tripped over a bento box on his doorstep.

the greenette bent down to pick it up, an orange sticky stuck on the lid.

: I hate owing people shit. thanks for the cookies. here's some lunch I guess.

ps: give me that recipe!!

izuku let out a loud giggle. quickly making time to leave a thank you note on his neighbors door.

: it looks delicious! thanks kacchan :)

ps: no can do! it's a secret family recipe. maybe, I'll sell you the cookies if you want haha.

Izuku walked to work with a kick in his step that day. katsuki really is a funny neighbor.

: you cheeky shit. you're lucky I liked them that much that I actually considered it.

the cookies and bento exchange started a weird tradition that bkdk started. izuku repaid back katsuki with more cookies.

: these are free, but don't get any ideas. next time they're a dollar a pop!

followed by katsuki giving izuku some of his dinner in return. he was definitely going to preserve these instead of scarfing them down like last time.

: I ain't buying shit from you. now if it was banana nut muffins. I might reconsider.. >:)

ps: I made curry, so theres that. eat it.

and izuku loved the curry, it was a bit too spicy for his tastes but he'd come to realize kacchan was an amazing cook.

the greenette did make him the banana nut muffins bc he loves to please, but he added the Midoriya twist. only to receive several sticky notes of crude admiration stuck on his door and a bento box on the floor.

: HOLY FUCK
: I want to marry your muffins
: give us your blessing.
: gonna make babies with them and make more muffins.
: GIVE ME THE RECIPE!
: deku I'll pry the recipe off your cold dead hands if I have to.
: made an extra bento by mistake. here.

izuku had a blast reading through all of them. chuckling to himself as he took them off and placed them on his kitchen counter. he took the bento and headed to work, humming to himself.

they exchanged more food and things were going pretty smoothly in terms of their mutual weird neighborly friendship. besides the sticky notes and food. they hadn't exchanged numbers or even seen each other in person.

izuku didn't mind. he was a bit shy and really only had one friend. but something in the back of his mind wanted to make more friends.

maybe katsuki could be a friend to him. he seemed like he was also in his 20s or maybe 30s.

so one weekend, izuku decided to take a few sips of liquid courage and finally meet his neighbor and maybe ask to hangout sometime without hopefully not coming off too gay. bc from what izuku has /heard/. katsuki was straight.

just when Izuku finally went through several scenarios in his head. he heard noises coming from katsuki's room.

there was some light laughter and then suddenly there was a moan.

oh. nevermind. he won't be going over anymore.

izuku could barely hear a few whispers and the mattress creaking beneath them.

at least he was being quiet this time...

except when the momentum began to increase and the sound of skin slapping skin echoed, moans growing louder.

could it be he got back with his girlfriend? izuku pondered.

but then the other person whined aloud, "I'm so close—ahh!"

that-that was not a woman. izuku knew how katsuki sounded and that wasn't him. Izuku suddenly walked out his bedroom with heated cheeks.

oh, god.

i mean, good for him. he got over his ex and was thriving. but now izuku couldn't stop thinking of the fact that he practically almost asked out his neighbor. and just maybe he was overthinking just about every quasi-encounter they had up to this point.

the teasing and silly jokes he had put on those notes were his own awkward way of lightly flirting but he figured katsuki was straight so he wasn't going to catch on. and now.. well now, he was fucking embarrassed.

Izuku had to down the rest of his wine.

after the revelation, izuku kept his guard up a bit. mainly because the night of, he dreamt of a faceless man with Katsuki's husky voice moaning in his ear on his bed, making him whine like the man katsuki was with that night.

izuku didn't even know what his neighbor looked like or his age!! it still had him waking up parched, with the hardest morning wood of his life.

finally, after 6 months of shared food and sticky notes, katsuki and Izuku met in person.

not on purpose, per se, but they walked by each other in the park while they were working out. katsuki was on vacation from his job and Izuku had just finished his summer term. so he was able to get back to his workout routine.

they didn't talk or anything. still izuku had to look back at the buff blond that had walked past him, wearing a black tight tank top and joggers, that showed off his impressive physique.

damn, he was hot. izuku could help but bite his lip.

he was definitely out of his league.

izuku hadn't noticed the blond whip his head back to get a better look at the shorter male that walked past him in ugly green tights and matching jumper, that clashed with his hair. giving that ass another quick glance before continuing his jog.

the months after were a bit quiet. certain days, katsuki would leave a sticky note with Izuku's mail and Izuku would do the same.

there was a time katsuki left izuku some leftovers on his doorstep, with a sticky note that read,

: made too much again. also tried to make cookies... I gagged. tell me your secrets deku!!!

izuku smiled half-heartedly, wanting to pay him back by baking him what he asked but izuku couldn't seem to look past the fact that he somehow ended up crushing on this faceless man.

he didn't even realize when it began or how. but he was beginning to look forward to the meals he'd make for him and he'd find himself singing while baking and smiling to himself, thinking about the reaction kacchan would have and semi hoping he'd be able to see it one day.

or the fact that he hadn't thrown out any of the sticky notes katsuki left him. he just began pasting them on a bowl on his kitchen counter, overlapping them as they came.

he couldn't stop his dreams either. izuku knew he was overthinking and making a big fuss over nothing.

cw: light angst
.
.
Izuku's thoughts were pushed to the side when he received an unfortunate call that his mother was in the hospital.

the hospital staff on the other line were being vague and off putting with the details. so izuku was downright yelling into his

phone, fat tears rolling down his cheek.

"how is she?!"
"can I go see her?"
"surgery? for what?"
"how do you not know?!"
"can you fucking ask?"
"no, I'm not going to calm down! my mom is in critical condition and you can't even tell me the details?! fuck you."

"...okay. I'll be right there."

izuku was out of his apartment before he even hung up.

completely unaware that his neighbor had been home and heard the entire thing.

...

katsuki talked a lot of shit about wanting Izuku’s pastry recipes but really baking wasn't his forte.

he's tried... even savory dishes that require baking were a problem for him. which is why despite his love for cooking, he never persued a career in culinary arts.

and also because he wanted to continue the doctor bakugou lineage.

so, while he finished school, Katsuki found a job as a security guard at the hospital his dad worked at. it paid decent enough that he was able to live on his own while he continued his studies during the day

and worked during the night.

the blond lived off 4 - 5 hours of sleep on a good day. but he managed to still keep his head up by cooking and tending to his mangy cat that had scratched up everything in its wake. he has friends too but those fuckers can be annoying.

he has always been a bit bratty and kind of rude but his friends and family knew better. katsuki cared about people, in his own way.

when his friends went through something, he'd just let them vent, broodily sitting next to them deadpanned while he listened.

the next day you'd find a plate of food or bento being handed to you as a way of saying, "I'm here for you."

food has always been comforting to him. but also katsuki sucks at feelings.

so this was his weird way of trying to reciprocate that without having to talk.

after a while, people caught on and thanked him for it and well, katsuki kept at it.

he only cooked for people he cared about so consider yourself lucky if you ever got a taste of katsuki's cooking.

fast forward to the present, katsuki is still the same as ever. cooking for those he cares about without having to talk.

since moving into his apartment, it's been a bit lonely and after the whole fiasco of his long term gf cheating on him. it was worse.

but then he found hope in the shape of a cookie.

katsuki's neighbor deku was hilarious. since he moved in, the guy's been obsessed with sticky notes or something bc he left them for everything. the blond thought it was funny, though.

but he didn't know that fucker could bake. not going to lie, he was a bit jealous. which is why he was so adament in showing off his cooking skills. before he realized it they were exchanging food and mail. it was nice.

katsuki doesn't know why, but he had a good feeling about

deku. he seemed like a good person and he enjoyed receiving his notes and pastries. it was a small thing in his life that started making his days brighter. he was a pretty quiet neighbor too; kept to himself and didn't bother him.

so when he overheard the yelling coming from his apartment, katsuki was stunned and mildly curious. he leaned closer to the wall to hear better.

after hearing everything, katsuki wished he hadn't. he hardly knew deku but he felt bad for him. having a sick mother,

that's got to be tough. katsuki feels compelled to comfort him, he doesn't know why. he just did.

after almost three hours of cooking and /baking/...

katsuki was grimey, a bit sweaty and covered in flour. but he was proud of the work he had done.

there were several types of dishes packed up in containers and ugly shaped pb and chocolate chip cookies cooling on a rack.

katsuki let out a happy sigh as he packed up a container with katsudon. it hadn't dawned on him that this was going to be hard to keep it discreet.

like, "btw here's a feast for no reason.."

but the blond had been too happy with the results that he hadn't thought about that. well, everything except the cookies... he hadn't tried them yet and he wasn't going to. bc ignorance was better than disappointment.

after writing up a few notes to add to the gesture. katsuki was too excited to wait. so he decided to leave them on his doorstep so he'd be surprised when he got home.

hoping that it'd make him feel a little better just like deku made him feel months ago.

sorry guys a bit of an interlude update from katsuki's POV. but I'm gonna add more later to make up for it
