A QUIET DEVOTION
Authorâs Note
eeeek!! Okay this is my first fic and I worked really hard on it and care way too much. Weekly updates. (hopefully!) Long Form because I don't know how to not include every single thought I have into a story apparently.
This is a post-canon continuation fic eight-year time skip story that begins the moment Deku learns the truth, and realizes the last eight years were never empty at all. They were full of someone elseâs quiet devotion, carried silently, deliberately, without expectation of recognition. Bakugo and Izuku have always been part of each otherâs lives, but adulthood, trauma, and time have changed the way they orbit. The story focuses on reconnection into slice of life.
A few notes going in:
This fic is written in alternating first-person POV (Bakugo / Deku). Each chapter stays fully inside one characterâs head.
Slow, emotional, and character-driven. Lots of internal monologue, dialogue, memory, and quiet moments.
PTSD, survivorâs guilt, and war aftermath are explored gradually and honestly, including therapy later on.
Romance is intentional, soft, and earned. Physical intimacy appears later and only where it makes emotional sense.
Izuku is a teacher at U.A. at the start of the story. Bakugo is a Pro Hero
Updates are planned weekly, with longer chapters that sometimes span multiple parts.
This is a story about what happens after. Its about endurance, choice, and finding home in someone whoâs always known your name.
Thank you for reading and if you hate it just lie to me hehehe đĽđ
CHAPTER ONE: THE WEIGHT OF IT
(DEKU POV)

âââââââââââââââââââââââââââââââââââââââââ
âWhy did you do this?â
The words are out of my mouth before I realize Iâve decided to say them, which feels fitting, honestly, because thatâs been the theme of my life, it seems.
Kacchan doesnât answer right away.
Weâre standing in a UA hallway. You can hear the noise of our friends and classmates in the room beside us. They threw me an after party that feels like a reunion. Just an hour ago I was flying through the city with my old friends. Once again.
Heâs more relaxed than I remember. Or maybe Iâm just more aware of it now. The energy he radiates. The way he stands like heâs prepared but content.
âIzuku,â he says finally, and my brain short circuits just a little because he says my name like that now. Careful. Deliberate. Like heâs still getting used to the shape of it. âIâm not having this conversation in the hallway.â
Oh. So he knows this is a conversation. So I wasnât imagining the weight of it pressing on my ribs the second All Might handed me the suit and smiled like he was passing on a second torch instead of detonating my entire understanding of the last eight years.
âOkay,â I say too quickly. âOkay. Thatâs... fine. We can...â
Kacchan exhales through his nose, sharp but controlled, and gestures with his chin toward the exit. âCome on.â
We walk.
The silence between us isnât hostile. Itâs worse than that. Itâs dense. Familiar. Silence that comes from knowing each other too well and not knowing how to speak without hitting something raw and explosive.
I canât stop thinking about the suit.
Itâs heavy in a way that has nothing to do with its actual weight. Itâs the knowledge. The understanding that didnât land all at once but in slow, sickening pieces.
Eight years.
Eight years of my life that I thought were quiet. Separate. Ordinary in the way adulthood pretends to be when you survive something catastrophic and then everyone moves on. What else could we do? Itâs natural to lose touch after graduating, anyways. I tell myself often.
I get into Kacchanâs car without thinking. He drives with hands steady on the wheel, eyes forward, jaw tight. The radio is off. Of course it is.
âHow long,â I say, because if I donât ask now I might not be able to later, âwere you planning to keep this from me?â
His fingers flex once on the steering wheel.
âWasnât planning on telling you at all,â he says flatly.
Ugh. That shouldnât hurt.
It does.
I swallow. âYou realize that makes it worse, right?â
He glances at me, sharp and quick. âYou asked why I did it. Not how I planned to explain it.â
âThatâs the same thing,â I say, and my voice cracks just a little, which I absolutely do not appreciate right now. âYou donât get to spend... what... years? A decade? Working on something like this and then act like itâs just⌠practical. NOOooOOOooo big deal.â
âIt was practical.â
âKacchan. You built me a hero suit that mimics a quirk I lost at sixteen. You funded most of it yourself. All might said you wrote notebooks. Multiple notebooks. Full of analysis about how I move. Thatâs not practical. Thatâs...â
I stop.
Because I donât actually know what word goes there yet.
He pulls the car over harder than necessary and turns it off.
âGet out,â he says.
My heart jumps. â...What?â
âNot kicking you out,â he snaps. âIâm just not doing this while driving.â
I get out slowly and we sit on the warm hood of his car, the night air cool and grounding, city lights humming around us. It feels like standing on the edge of somewhere high and realizing too late that youâre already leaning forward.
Kacchan crosses his arms. âSay it.â
âSay what?â
âWhat youâre dancing around,â he says. âYou didnât come here just to thank me.â
I open my mouth. Close it. Open it again.
âI donât know what this means,â I say, finally honest in the way that matters. âI donât know how to hold it. I donât know how to exist in a world where you did all this and didnât think I deserved to know. I donât know how to analyze it, how to⌠categorize it.â
âNerd,â he offers first sarcastically, before his jaw tightens.
I can tell when heâs about to say something serious.
He gets quieter first. Not calm. Contained. Like heâs bracing against himself. His shoulders go rigid, his jaw sets, and he stops looking at me. The eye contact might actually undo him.
ââŚIâm not good at this.â
My chest tightens.
I donât interrupt. I donât say his name. Iâve learned, the hard way, that this is the moment you donât touch the thread. You let him pull it himself.
âI donât know when it started,â he says, voice rough, like itâs scraping its way out. âEveryone always wants a moment. Like itâs supposed to be some big damn realization. A switch flipping.â
He huffs a humorless breath.
âI donât have that.â
He finally looks at me, eyes sharp and unguarded in a way that makes me anxious.
âYou were just always there.â
I soften.
âEver since we were kids,â he continues. âYou chasing after me. Watching me. Looking at me like I was something worth understanding instead of something to beat.â
My throat tightens. I remember that. I remember everything.
âYou pissed me off,â he says flatly. âBecause you wouldnât stay down. Because no matter how many times I told you to quit, you kept getting back up. Because you understood me in ways I wasnât ready for.â
He clenches his fists.
âI told myself it scared me because you were weak.â
I flinch. Itâs reflexive. Old.
âTurns out,â he says, quieter now, âit scared me because you werenât. Because you had a heart that is so... beautiful.â He winced like he canât believe he just said that out loud.
âYou ran toward danger without a quirk,â he says. âNo matter how much it cost you. You broke your body over and over and smiled like it didnât matter.â
My eyes burn.
âAnd somewhere along the way,â he admits, voice cracking just barely, âit stopped being about rivalry. Stopped being about winning.â
He swallows.
âIt became about making sure you were still there. With me.â
My breath stutters.
âWe didnât get time to figure it out,â he goes on, words coming faster now, like the damâs finally giving. âNot really. We went from kids... to world saving heroes in the span of a year. From school to battlefields. From stupid fights to international icons.â
âYou didnât deserve to carry it.â
âThatâs not your burden,â I try to say.
âYeah,â he snaps. âIt was.â
We stare at each other, the air between us electric and brittle. Our whole lives have been miscommunication. Bad communication. War communication. And now, to continue that trend... absent communication.
I think about headlines. About statues. About kids wearing my face on their backpacks. My classmates opening agencies. Kacchan becoming an amazing pro hero, take down after take down. About how everyone told me Iâd done enough while something in me kept insisting that enough wasnât the same as finished. The last decade has felt like a dream. Not good or bad. Just⌠unbelievable.
âWhy,â I ask quietly, âdid you start?â
The word hangs between us. Thin and dangerous.
Why.
He doesnât answer right away. Heâs holding himself together. âKacchan,â I say again, faster now, because panicâs creeping in, âIâm not trying to corner you. I just⌠this matters to me. You matter to me. And I canât pretend this is nothing when itâs clearly not nothing.â
âI didnât start,â he says finally, and his voice is low and calm. âIt wasnât a decision. It was just... what needed doing.â
âThatâs not an answer,â I say, gently but firmly, because Iâve learned that backing down from him never gets either of us anywhere.
He takes a long, deep breath.Â
âI watched you save the world,â he says. Controlled. But thereâs something shaking underneath. âI watched you take on every single thing no one else could handle. You didnât hesitate. You didnât complain. You didnât even ask if it was fair.â
My throat tightens.
âYou were sixteen,â he continues, and now his voice cracks just enough that it feels like a knife twisting in my chest. âSixteen. And they handed you the whole damn war.â
I swallow. âKacchanââ
âYou donât get to interrupt this,â he snaps, but thereâs no heat in it. Just desperation. âAnd you DONâT get to downplay it.â
He finally looks at me then. Really looks at me. Thereâs something raw in his eyes that Iâve never seen turned outward like this before.
âYou won,â he says. âYou did it. You saved everyone. The greatest hero, Deku! And then you lost your quirk?! You lost the vestiges.â He brushes my cheek with his thumb. âYou lost your freckles.â he says almost in mourning.
âYou lost the thing you waited your whole life for,â he says, words coming out slower now, heavier, like heâs dragging them up from somewhere deep and uncomfortable. âYou didnât bitch about it. You didnât quit. You just⌠adjusted. Like it was normal. With a smile on your face, saying youâre fine.â
He scrubs a hand through his hair, frustrated, pacing now because standing still feels like he might implode.
âYou know how fucked that is?â he says. âWatching you do that? Watching you smile and say itâs fine?â
I feel like I canât breathe.Â
His laugh is short and humorless. âYou always say youâre fine.â
âWell, I wasnât!â he says quietly now. âI havenât been. Not since I watched them cheer for you while you were still breaking.â
The night feels unbearably still. Every sound distant. Like the world has pulled back to give him room.
His hands shake. Just a little. He notices. Clenches them harder.
âI needed you,â he says, and this time thereâs no armor left on the words. âI still do! I need you beside me. Not behind me. Not watching from the sidelines pretending youâre okay with it. Beside me.â
My eyes burn.
âYouâve always been a hero,â he says fiercely. âQuirk or no quirk. Suit or no suit. That never changed. But the suit...â He swallows. âThe suit gives you the option back. It brings you back to me.â
Something in my chest breaks open.
âIs that⌠is that all it was?â I ask softly. âBecause you missed me in the field?â
Kacchan laughs again, but this one cracks halfway through. âYou really donât get it.â
âThen help me get it!â I plead, stepping closer, and oh god, heâs close now. Too close. Close enough that I can see the scar on his face, the scarlet in his eyes, the sweat on his neck.
âWhy do you care this much?â I insist. âWhy me? Why spend years of your life making sure I could come back when you couldâve just⌠moved on? And why do it all without talking to me? Iâve felt like Iâve lost touch with all my friends.â
I soften. I didnât mean to say all this.
âIâm incredibly happy for everyone, of course, but⌠I just missed the small moments. Dinner with my friends.â
âYeah,â he says flatly. Defeat. Or acknowledgement. âWe graduated and the space grew more and more. I couldnât do anything about it at first,â he admits, voice dropping.
âI wasnât... in a good place.â
The words feel dark and heavy. Serious.
âI was somehow angrier. Guilty. Messed up in ways I didnât know how to fix yet. My head was a mess. So I worked. I trained. I went to therapy. I fixed myself piece by piece. And while I did that, I worked on this.â
He gestures vaguely, like the idea of it still feels too big to point at directly.
âI filled notebooks,â he offers with a smirk, like he knows Iâll be tickled by this information. âJust like you do. Wrote down how you move. How you think. How you fight. How you care. I brought them to Hatsume. Took extra shifts. Did overnights. Didnât give a shit about rankings.â
âSo yeah,â he finishes, quieter, steadier, eyes locked on mine. âThatâs why I started.â
âI want every version of my life to include you in it. Every future I imagine, you are there.â He quickly throws in.
Iâm openly crying now. I donât even care.
âAnd thatâs not friendship,â he adds. âIâm not that stupid. I donât know what this is, but if it helps you categorize it... itâs not friendship. At least on my end.â
I canât speak. I donât trust my voice. My heart feels too full. Too raw. Like if I say his name it might split me open completely.
My fingers brush his knuckles first. Accidental. I think. At least at first...
âKacchan,â I say quietly.
I lace my fingers through his before I can overthink it. Before I can talk myself out of it. And for a split second Iâm terrified heâs going to pull away. That heâll snap. That I crossed a line.
But he doesnât.
His hand tightens around mine instead. I melt.
Itâs warm. Rough. Familiar in a way that feels brand new. Like Iâve known this shape my whole life but never realized what it was for.
We stand there like that. Not moving. Not talking. Just⌠holding hands.
He hesitates, just for a second, then lifts his free hand and cups my face like heâs holding something sacred and breakable.
âYou deserve a future where you get to choose,â he says. âAnd wherever you go... whatever you decide... I want to be there.â
His thumb brushes my cheek, wiping a tear.
âNot as your rival,â he says. âNot as your shadow.â
He looks at me like heâs offering a promise.
âAs yours.â
My thoughts slow. Not stop. Never stop. But they soften enough for me to realize...
This isnât gratitude. This isnât obligation. This is him choosing me.
And I devastatingly understand.
The suit wasnât the beginning. It was the proof.
This is something weâve been avoiding our entire lives. And there is no going back to before this moment.
The moment he truly became my Kacchan.
