[1k words. tomura x reader, background/implied dabi x reader. in which dabi flirts shamelessly with you and tomura is heavily unconcerned.]
wrote a little thing inspired by something my friend shared with me and i ran with it. it's the shortest and quickest thing i've ever written haha but i love the way it turned out. enjoy some cocky confident definitely not-jealous boyfriend tomura ;]
From beneath the hair that falls in his face, from between Father's fingers, Tomura's eyes track your reflection in the bar mirror. He watches your face light up as The League, sprawled across two booths behind him, greets you, and traces your every footfall as you sidle up beside him.
"Hey," you say, your voice quiet, the softness in it just for him as you nudge against his shoulder.
He hands you your drink, he'd had Kurogiri make it just the way he knows you like it, and you squeeze his arm in thanks, when Toga hails you to come sit with her.
"Can have a seat here, dollface," he hears Dabi say as you approach their table, and scowls as he watches him drop one of his legs to the ground, the other still languidly stretched across the entire booth.
Dabi, like the rest of them, only joined The League a week ago, but, Dabi, unlike the rest of them, is already acting like he owns the place, that sleazy, false confidence hanging over him in a haze, wafting off him like smoke.
"I don't think there's enough room for me and your ego," you quip, stepping toward Toga's side of the table, but Tomura can hear the pleasure in your tone.
So does Dabi, saying nothing but grinning as he closes his eyes, his hands threaded behind his head.
"Here, here," Toga coos. "Scootch, Jin-kun."
You sit, and Toga launches into some story, the two of you huddled over her phone.
Tomura's eyes are glued on Dabi's foot, on its sly progress toward yours, and when his boot comes to rest propped atop your own, you don't move it.
You prop your arm on the table and lean your head against your knuckles.
But not before Tomura watches a blush creep up your neck.
He drains his drink and pushes away from the bar, turning in time to see Dabi smirk, his eyes still closed, his boot retreating deep into the shadows beneath the table, and you give an almost imperceptible start, your frame suddenly a little too still, giving you away, as he leaves the room.
But you're both wrong.
Tomura isn't jealous.
Because you're his.
You're hot. Tomura knows this, of course, knows that guys just can't help wanting you.
It doesn't bother him.
He doesn't feel the need to hide you or force them to avert their eyes.
In fact, he loves the looks on their faces when you're on his arm.
He knows it makes you feel good, too, and that's fine. It should. You deserve to know you're hot, even if it's not him who's telling you.
So Dabi could ogle you all he wanted.
Because Tomura knows no one can appreciate those deeper parts of you like he can, the bits that make you you.
He grins, knowing they'll never know how you process things, stringing your thoughts like clothes on a line, shaking them out before letting them dry.
He glows, knowing they'll never understand the way you really wear your heart on your sleeve, all of your micro-expressions flitting across your features like a silent movie that only he had bothered to understand.
He feels alive, knowing they'll never appreciate that you care so much what people think of you, even though you hate it, or how often those cracks in your composure threaten to break you, but still you soldier on, his brave brave girl.
Dabi had figured out he could flatter you, his flames flashier than any neon billboard in the city, hot enough to melt steel.
But Tomura knows, just as he knows you know, that it costs him nothing, which is why, for all his flare, Dabi can't hold a candle to him, to what you and he had built, together.
Tomura had put in the work, had dug his fingers slowly into you and painstakingly pried you open. And you had let him.
The most precious gift you could have ever given. And you'd given it to him.
So when you enter his room, some minutes later, with a soft little smile toying at your lips, with Dabi's sugar bubbling in your stomach, spreading through you and making you giddy, Tomura doesn't rise.
Yes, he'd prefer you only make those smiles because of him. Of course, it bothers him that someone else gave you that.
But he'll revel in anything that delights you.
Because he's not some jealous, pathetic, insecure boy.
"Dabi likes the name," you tell him, the slightest lilt to your voice. "The Vanguard Action Squad."
Tomura snorts, not bothering to look up from his handheld, even as you work his legs apart to stand between them, your fingers toying with his hair. "I don't give a fuck what Dabi likes."
"You came up with it." Your implication sits at the tip of your tongue, but Tomura waits, knowing it'll come tumbling out. You just can't help yourself, and he loves that you have no secrets from him.
"Guess you're more similar than you think," you say, goading him like you do, and Tomura feels his back straighten. It makes him mad when you do this shit. But it strokes his ego too. You just want his attention, and god that makes him hard.
"Sure, we have some overlapping interests," he allows, then shifts his eyes to where you stare down at him. "The same woman, for instance."
He watches your eyebrows raise, your smile twitching ever slightly wider, your expressions admitting you think he hadn't noticed.
And that is just too cute.
Tomura had known you liked the attention Dabi showed you before even you did.
"Unfortunately for him," he continues, sweeping his eyes back down to the game in his hands, his voice effortlessly level, supremely unbothered, "she belongs to me."
He can almost hear your breath catch, your pulse quicken.
"He and I," he gets out before you lift the game out of his hands and straddle him, "we're not the same."
Tomura's grin is knowing as you bend down and press your lips to his, exhaling that spent sugar into his open mouth.

...
The sound registers slowly, too slowly, because there's no way that was the front door.
Because you could swear he wasn't supposed to be home until later, that you had another several hours until he made his usual stop in your doorway to greet you, like he does on the days you get home before him.
But by the time your brain realizes what you heard and what it means, it's too late.
Your wide eyes dart to your open bedroom door just as Shinsou comes into view.
"Nnononono," you babble, finally wrenching your arms free of Tomura's grip, flying to cover your chest.
"Oh, shit!" Shinsou yells.
You register the shock in his face with acute clarity before you're bending forward in a panicked attempt to hide, your face burning. "Don't look! Ohmygod, ohhhh my fucking god…"
You can hear Shinsou backpedaling out of your room, "Dude… what the fuck," hear the door being pulled shut -
But then Tomura calls, "Oi, hang on, Shinsou-kun…"

Sensei was here. He'd come.
The smile spread across his face even as his guts twisted, sending weird gurgling laughs leaping up his throat like bursts of lava before an eruption. But a second later, he clamped a hand over his mouth, buckling over as the laughter turned to bile and he had to swallow hard to keep it down.
He heard Shinsou give him one last tch before heading toward Circuit Board Face's office, shouting, "Silicon-sensei, we need to call Aizawa-sensei!"
"WORKING ON IT," the A.I. voice chirped.
That's right, Tomura thought, I'm at UA.
With the sudden appearance of his master — his guardian, his caretaker — he'd momentarily forgotten his current reality.
This was a hero run, not durge. He was at UA, not with The League. And Sensei was there, not here.
Tomura stood upright again, wiping drool from his mouth with the back of his hand, and saw Kyou staring at him.
Dame da¹.
He looked away. She had that look on her face again. The one she'd worn back when she'd discovered who he was, who he really was. When he'd pinned her down and patronized her, shown her just how naive she'd been and how cruel he was. When her eyes were all he could see, full of fear, full of hate.
"Wasn't the whole point of us coming here," he heard Shinsou grumble from the next room, and he turned his head, welcoming the interruption from his thoughts, "so that we could have a secure connection to him? Why isn't it already established?"
A series of sporadic beeps and static issued momentarily over the room's speakers, then the smooth voice returned. "I CAN MAKE ALINE SECURE IMMEDIATELY IF IT'S INCOMING. OUTGOING TAKES A BIT LONGER. THANK YOU FOR YOUR PATIENCE."
Shinsou was in the office now, crossing and uncrossing his arms as he glanced from screen to screen behind the computer-like heteromorph.
'What now, Tomura?'
The deep voice sounded unbidden from his memory.
Tomura focused on the chaotic video feed, feeling reality swell into sharp focus around him.
Sensei was there.
And he wasn't.
Tomura could still feel Kyouyuu's heavy eyes on him. He watched the nomu on the screens above his head, watched as shape and sound and color began to swirl into a solid, painful mass. He felt it bulging behind his eyes as the mass grew, pulsing at the inside of his skull.
Now Sensei would know — know for sure — that Tomura wasn't with The League anymore.
Would he think he'd been captured?
No. No, Sensei knows I'm more capable than that.
His grit his teeth, hating himself, as his skull throbbed again. Because not being captured meant that Sensei would know he'd willingly left The League, surrendered his position. The position Sensei had gifted him.
Sensei will know I've abandoned him.
Cold crept from everywhere, a chill so menacing it rooted him to the spot as it clawed its way up his limbs, grasped his throat, gripped his head, covered his face.
What had he done??
He'd made the wrong decision. To abandon all he'd known. All he'd worked for. All Sensei had done for him. And now, Sensei was sending the nomu to help him, determined not to let him fail. But here he was, betraying him...
His vision was gone. His breath came in short shallow bursts.
But wait…
Why would Sensei send the nomu? Kurogiri could've curried them over instantly, the second that All Might had smashed through the wall. But he hadn't. Was it because he couldn't?
The only reason Kurogiri couldn't have brought them, was if…
Was if they weren't there.
Tomura felt as if he were falling through nothing.
Even after all of his work, after all of his meticulous planning, Sensei had a secret backup plan.
Sensei had never trusted him to pull this off, never believed in his plan.
Sensei had moved the nomu without telling him.
"Sensei…"
Tomura heard the honorific fall from his mouth like toxic sludge from an overturned barrel, as the silence began pressing in like a trash compactor.
Sensei always believed I would fail.
The cold was deep enough to drown him. He felt as small as he did on that day all those years ago, barefoot and bloody. Alone.
"…mura…" a hesitant voice echoed distantly, a haunting melody in the void.
Kyouyuu.
He felt his shoulders haunch, his body coiling in on itself, protecting an ache deep in his chest. He grit his teeth again, his groan vibrating throughout his bruised skull.
Where was she?
Why couldn't he touch her?
He needed her touch!
The reason I stayed…
Gentle, steadying, kind.
Her touch made it all...
Better.
She made it all...
Please.
Kyouyuu.
"Make it go away!" he choked.
"Everyone," he heard her call, her voice slicing the air like a saber, "please trust me!"
He heard Shinsou shouting, the AI voice chiming, both deafening.
And then light burst through, so blinding that he tried to twist away from it, except that his wrists were held tight in her tiny grip.
He felt his arms thrust high into the air, and he buried his head into his bicep, groaning and grinding his ear against the noise, his eyes snapped shut against the deluge of his senses all being turned back on at once.
It was painful. And warm. And something other than the cold void.
But the reprieve was short lived because electricity — not a warning shot this time, but a direct hit — coursed through every inch of him, from the soles of his loaned hospital slippers to each hair follicle on his head.
Rose Quartz Dawn is Part I of my 3 part BNHA series, One by One, a canon-adjacent AU in which Tomura Shigaraki is saved. Starring everyone's favorite blue haired, itchy, chaos-loving gamer boi, and my pink-eyed, analytic, Support Course student OC with psychometric skin, Kyouyuu Atae.
