Chapter Text
On your seventeenth birthday at exactly 12 AM you get your soul mark. Whether it be writing on your once smooth, unsoiled skin or a mark that ties with your soulmate, it will be there. There’s no running from it. Soul marks can be any size or color. They can be practically anything.
The mark could be something that symbolises your soulmate. An animal that’s tied to them, a favourite flower or plant or thing. It could be anything . It just has to be about them. You can either get writing or the mark or in some cases both.
The words can be anything from any point in your life. It doesn’t have to be something you’ve said to them yet. It could be words from the first meeting, a familiar phrase, something that impacted your life, a phrase that'll stick with you, a sentence that’ll be said as you pass by each other or the last meeting you’ll ever have.
People have gone their whole lives without ever knowing who their soulmate is. They still lived their normally happy lives with people that weren’t “bound” to be with them forever. The worst case scenario is finding out when it’s too late. About to draw your last breath. About to finally be free from the world. About to be at peace. Then hearing the words they’ve wanted to hear since well, forever. People can spend their whole lives looking for their soulmate only to find out when they’re about to die? That’s fucked .
Which is why Katsuki could give less of a shit about soulmates. Honestly, he thinks they’re idiotic. He’s just given any person the universe decides to throw at him to live with forever.
What a load of crap.
Katsuki’s already made up his mind that he’s going to ignore it. Fuck that . He doesn’t give a shit about any words on his skin that are only there to determine the person he’s “destined” to be stuck with for life. There’s more important things in life and the assumption that shitty markings on his skin would determine his whole life was crap. Fuck you universe.
If it wasn’t made clear earlier he didn’t give a shit. He wasn’t gonna be like the other shitty extras and stay up just to see a stupid soul mark. Fuck no. He was going to stick to his normal bed time and go the fuck to sleep because the universe doesn’t control him. So that’s what he did. He did his homework and went right to bed at 8:30.

Katsuki woke up the next day to his phone overflowing with messages and calls from his nosy friends and his parents. It’s 5 AM and frankly, he doesn’t have time for this shit. He got up, put his running shoes on, threw on a tank top and grey sweatpants and made his way through the door. He wasn’t about to let some nosy fuckers get in the way of his routine.
He doesn’t know why they even care so much? It could be some shitty extra he’ll never even cross paths with. Soulmates don’t define him or control who he’ll love— if he even decides to love anybody. Becoming the number one hero is more important and fuck if he’ll let someone get in his way.

When he’s finally back at the dorms he prays to every god there that he won't run into his idiot brigade and thankfully, for once, his prayers are answered. If he gets ready faster than he normally would then maybe he just wanted to be extra early for class that day. He’s not going to class with an empty stomach because unlike Deku, he has self preservation and knows his limits. A quick peanut butter sandwich should do the trick and wont occupy him enough so that anyone comes down here with him.
He takes his sandwich and storms out the door headed straight to class. When he gets there Iida is already there, like always, which makes him wonder if that fucker even sleeps at night. He ignores his presence and makes a beeline for his seat. Twenty minutes later the other extras finally make their way through the door.
“HEY BAKUBRO!” Kirishima shouts, eerily cheerful as soon as he steps through the door as if it isn’t 7 in the morning.
“Keep your voice down you noisy fucker.”
“Whoops, sorry about that man” That stupid grin is still plastered on his face and Kirishima practically skips over to his seat and plops right onto his table.
“Get the hell up hair for brains.”
“So did you figure out who it was?”
“Who what was?” What the hell is he even talking about?
“Uh.. Your soulmate?” Kirishima inquired, tilting his head and looking as if he’d just heard the most idiotic thing ever.
At the mention of soulmates Katsuki rolls his eyes and groans. Fucking of course. Should've expected his nosy ass to ask about it.
“I haven’t looked at-.”
“YOU HAVEN’T LOOKED?!” Kirishima blurts bolting off the table staring incredulously as if he was told that Crimson Riot was the worst fucking hero ever and Katsuki makes his signature scowl.
“Keep your fucking voice down Shitty Hair!”
“Sorry bro.. But what do you mean you haven’t looked?”
Katsuki scoffs and rolls his eyes, “I haven’t looked. Did the few brain cells you have left stop working or some shit?”
“Sorry I’m having a hard time understanding this. YOU HAVEN’T LOOKED?”
“No?”
“Bro..”
“So what if I haven’t looked? It isn’t as if the world is ending or some shit.” Katsuki murmured, frowning and knitting his eyebrows together.
“BUT IT-”
“To your seats everyone.” Aizawa mumbles, emerging from his sleeping bag and when the everlasting fuck did he get here?
“This conversation isn’t over bro!”
“Fucking whatever. Get up”
Katsuki sighs, closing his eyes, tuning out whatever the hell Aizawa’s saying to think about what kind of atrocious act he’d done in his past life to deserve this. Sure he’s being a bit dramatic but hey, who gives a shit anyway?
*
Classes end for the day and Katsuki just about bolts it through the door to avoid his group of idiots annoying him about the mark. He practically ran out the door at lunch heading straight to the roof until the hour ended. Thus giving him a breather and the calm he needed before having to inevitably talk to the squad. He’s done a good job so far so he can continue for longer. He never wants to talk about that soul mark ever.
Sure he says he doesn’t give a shit and is putting on his nonchalant façade but somewhere deep down he’s silently wishing for only one specific person to be his soulmate. He ‘doesn’t care’ because he doesn’t want to get to get his fucking hopes up only to get let down so his best bet is shutting down the whole idea and forgetting about it for the rest of his life.
So yeah, never. He’d prefer keeping it secret for fucking ever but his idiots are annoying assholes that jump into his business every chance they get.
He successfully makes it back into his room without bumping into anybody and decides that if he isn’t going to hang out with the squad he’ll just do his homework and head straight to bed. Easy enough, right?
Wrong.
An hour later there’s pounding on his door, and if these fuckers dont stop beating his door down it’s going to break-
“STOP BEATING MY FUCKING DOOR DOWN.” Katsuki yells as he gets up from his desk, stalking over to the door and yanking it open.
“Bakubabe!” Mina squeals, practically throwing herself into his arms and squeezing the life out of him. “Get the fuck off me,” He grumbles shoving Mina out of his personal space back to the other idiots albeit delicately. He pulls his meanest scowl so that no would even dare to mention his thoughtful action. His face practically screams say anything about what I just did and i’ll melt your face off. It definitely works seeing as none of them bring it up.
“Fucking- what do you assholes want.” Katsuki gruffs out levelling the squad with the most menacing glare he can construct, hoping it’ll make them rethink their choices of practically barging into his room. (Spoiler Alert - it doesn’t. )
“Katsuki, my man, relax a little! We can’t just drop by our friend’s room to wish him a happy birthday like good friends should?” Denki jokes with the fakest fucking tone and the most mischievious smile he’s ever seen.
“No.” He pushes to close the door but Sero squeezes his hand in and stops the door from closing completely which honestly, he should just slam the door on his hand but he won’t because he doesn’t want to hear his god awful whining.
“Apapapa- you’re not getting out of this one Blasty.”
Katsuki sighs and opens the door wider to let them in, grumbling the most colourful curses he knows under his breath. Mina throws herself into his bed and the rest of the idiots follow suit. Monkey see, Monkey do I guess.
Katsuki stalks over to his desk and plops down onto the chair unceremoniously. “So. What do you idiots want?”
“What do we want? Bakugo, I think you already know the answer to that.” Sero says, staring him straight in the eyes.
Katsuki stares back for a moment then sighs, rubbing his hands down his face, taking a deep breath, “I swear if this is about my soul m-”
“It is.” Mina inquires, sitting up from her position on the bed.
“I still don’t understand why you losers are so adamant on knowing. The world isn’t going to end if you don’t know what or who it is.”
“Well.. yeah I guess.. but we’re curious bro! C’mon aren’t you even a little bit curious?”
“No? I’m not as interested in this soulmate bullshit as much as you are.”
Hearing that, both Mina and Denki pout staring at him as if he told them they aren’t his friends or some shit which pisses him off so much more.
Katsuki runs a hand through his hair and closes his eyes, trying to not let off an explosion in his room. “Look. Can you hop off my case about my soul mark? I’ll look when I want to.” Katsuki’s getting pissed off to no end and wants this conversation to end now. “Drop it.”
He opens his eyes and crosses his hands over his chest staring at the now silent squad. There’s complete silence in the room—save for his heavy breathing—but it’s silent enough to hear a pin drop.
Mina shoots a side eye glance at the squad for a second and looks back at Katsuki with a sympathetic smile on her face “Sure blasty,” she says, before shooting up out of the bed and claps her hands. “Since Blasty’s birthday isn’t over, how about we play some games and watch a movie?”
The squad looks up at her silently then turn back to him seemingly waiting for his answer. Scoffing and rolling his eyes, he agrees. “Sure, why not.” He grumbles out, watching the idiots as their faces light up with the largest grins he’s ever seen on their faces.
“DIBS ON PLAYING FIRST!” Denki screams jumping up looking seemingly proud of himself that he got the first word in.
Kirishima looks at him with a pout on his face and crosses his arms, “Bro, Not fair!” he grumbles, sounding extremely similar to a whiny seven year old when their parent refuses to give them more candy.
“Stop fucking whining shitty hair.”
“But- man that was so not fair!”
*
3 hours later, the squad’s finally gone and Katsuki finally has some fucking peace and quiet. He sighs and flops down on his bed being drained and worked out. The exhaustion from today is creeping it’s way to the surface and he wants nothing more for this day to be over with. He’s up way past his bedtime and all he wants to sleep but decides against it so he can change out of his long sleeved shirt because he does not want to risk letting off explosions in his sleep.
He gets up to change into a tank top and shorts and plops back on his bed. He groans, throwing his head back against his pillow, exhaustion creeping its way into his bones, he sighs raising an arm to cover his eyes but stops mid-way, eyes catching unfamiliar writing that he most definitely did not write and that’s when he finally processes what it is.
His fucking soulmark.
Katsuki bolts upright, staring at his arm. “What the actual fuck.” He holds his arm and stares at it wide-eyed rereading the sentence because—holy shit there’s no fucking way. How the hell did he not see it this whole time? This has to be some kind of sick joke the universe is playing on him. He’s staring at the writing rereading it like he’s a fucking idiot that can’t comprehend what the words are as he takes in a shaky breath, “Holy shit.”
He stares at the words dumbfounded because right there on his arm, scribbled in gold letters, carved out as if it were a brand. Marking him, standing out against his pale skin, practically glistening, as if it were always there. As if it was meant to be there.
Seeing the words is like a truck slamming into him at full speed because the words are so achingly familiar. He’s reread it so many times he can practically envision the scene, playing it over in his brain, he can just about hear his voice saying it to him. The sickeningly sweet inflection reverberating in Katsuki’s skull.
I can’t imagine a world without you.
Holy Shit. His soulmate is fucking Deku.
Izuku Midoriya is his soulmate.
Shit .
