The Neighbor Downstairs - Part Nine - Katsuki Bakugou x Reader
Part One <3 | Part Two <3 | Part Three <3 | Part Four <3 | Part Five <3 | Part Six <3 | Part Seven <3 | Part Eight <3
Summary: After a brutal overnight shift leaves you barely able to keep your eyes open, you accidentally fall asleep in the tub and flood the apartment beneath yours. You wake up to furious pounding on your door from none other than pro hero Katsuki Bakugo. He's forced to stay overnight, in your bed. Now that his mattress has been delivered, he's back to staying in his apartment.

Morning sunlight filtered dimly through your bedroom window. You barely noticed it.
Somewhere deep beneath sleep, your phone buzzed once against the nightstand before falling silent again. The sound barely registered through exhaustion still dragging heavily at your body after several days of work.
Downstairs, Katsuki was already awake.
Hero work meant inconsistent schedules. Today it meant he was leaving for an early patrol.
Still half dressed in dark compression gear, Katsuki poured coffee into two mugs automatically before stopping halfway through the motion.
His eyes narrowed faintly at the second cup.
“Tch.” The annoyed sound lacked any real heat. Apparently his body had also gotten too used to making enough for two.
Katsuki grabbed his phone off the counter while taking a long drink from his coffee. He sends a quick message.
Katsuki: Coffee downstairs.
He expected a response within five minutes. Ten at most. Normally you were quick to respond.
Katsuki frowned faintly while pulling on pieces of his hero gear one by one.
No response while he gathered equipment. No response while he checked patrol updates. No response while he headed downstairs toward the building exit. By the time he stepped outside into cool morning air, irritation had already started creeping beneath his skin.
Not because you hadn’t answered. Obviously.
People slept in. People got busy. That wasn’t the problem. The problem was that he kept checking his damn phone anyway.
By midmorning patrol, Katsuki had looked at his notifications at least seven separate times. His mood steadily worsened.
The city streets buzzed loudly around him while patrol stretched long beneath bright sunlight. Civilians watched when they spotted Dynamight overhead. Reporters lingered near one blocked off intersection downtown. Traffic noise echoed constantly between tall buildings.
Even with all the noise, part of his attention remained fixed stubbornly on his phone.
It was stupid. Especially because rationally, he knew exactly what happened. You were probably still asleep.
---
You woke up in a panic. The room was too bright when you opened your eyes. The clock beside your bed glared back at you.
You shot upright immediately.
“Oh no—” Your voice came out rough with sleep while you scrambled blindly for your phone buried somewhere beneath the blankets.
Several missed notifications lit up the screen. One from work. One from a friend. And one from Katsuki sent hours ago.
Katsuki: Coffee downstairs.
“Oh, shit.”
You launched yourself out of bed after that. The apartment became chaos for the next twenty minutes.
You brushed your teeth while pulling clothes on simultaneously. One shoe disappeared beneath the couch somehow. Your bag nearly got left behind entirely while rushing around the apartment trying desperately to wake yourself up enough to function. There wasn’t time for breakfast or coffee.
Your shift was somehow even worse.
The entire day felt nonstop from the moment you arrived. You barely had time to breathe between tasks, exhaustion already dragging at your body from oversleeping and rushing through the morning without food.
It wasn’t until well into the afternoon that you finally got a moment alone where you could check your phone properly. Guilt twisted in your stomach seeing Katsuki’s unanswered message still sitting there.
You typed quickly.
You: I’m sorry.
You: I slept through my alarm and nearly died getting to work on time.
The response came far quicker than expected.
Katsuki: Idiot.
A small smile graced your face as you leaned tiredly against the break room wall while typing another response.
You: Fair.
You: Thanks for the coffee offer though.
Katsuki: You’re welcome. You always take your sweet time waking up.
Even through text messages he somehow sounded exactly like himself. Another message appeared before you could lock your phone again.
Katsuki: When are you off?
You stared at the message for a second.
You: Late.
You: Like… really late. I’ll probably get home a little before 11.
The typing bubble appeared. Stopped. Appeared again.
Katsuki: That’s later than normal.
You laughed quietly under your breath.
You: I picked up this shift for my coworker. Unfortunately I enjoy having money.
Katsuki: Terrible personality trait.
The conversation continued slowly throughout the rest of the day after that. Just scattered messages squeezed between work and patrol whenever either of you found a free second.
The consistency of it settled warmly in your chest. Katsuki Bakugou was busy, always busy and yet he kept responding anyway.
Hours later, you managed to collapse into the break room with your lunch untouched beside you.
Your phone buzzed against the table.
Katsuki: You eat yet?
You stared at the message tiredly before answering.
You: About to.
You: Today’s been awful.
A response came a minute later.
Katsuki: Eat anyway.
You: I’m trying.
The rest of the shift dragged endlessly afterward.
By nighttime, your eyes were dry and your legs ached. The city outside had long since darkened by the time you finally left work.
All you wanted was sleep. Well, maybe a snack first. Then bed.
The apartment building remained quiet when you finally trudged upstairs sometime past midnight. You unlocked your apartment door slowly. The lights inside remained off except for the faint kitchen light still glowing softly across the apartment.
You frowned faintly. You definitely didn’t remember leaving that on. Your bag slipped from your shoulder while you wandered farther inside. Other than the light, the apartment looked normal.
Then, your eyes landed on the note sitting on the kitchen counter beside the fridge. Taped crookedly to the counter in familiar sharp handwriting, eat the damn food before bed.
You blinked slowly. When you opened the fridge, a neatly packed container of food sat inside.
“What the hell…”
You stared at the container another second before looking slowly around your apartment.
Did Katsuki break into your apartment?
The realization should probably concern you more than it did.
But somehow, after a full patrol shift and an early morning schedule, he’d still thought about whether or not you’d eaten dinner.
Your apartment suddenly felt less lonely.
You changed into sleep clothes while the food was heating in the microwave. The apartment remained dark and quiet around you while soft kitchen lighting spilled across the counters.
The first bite nearly made you groan. It absolutely unfair how good his cooking always was.
You grabbed your phone immediately afterward.
You: Thanks for the food.
You: Did you break into my apartment?
You stared at the message after sending it.
No response came.
Of course not. Katsuki was almost definitely asleep already. Even so, you found yourself smiling faintly anyway while eating dinner alone beneath the quiet apartment lights.
