If there was one thing Kirishima knew for sure? This whole situation put a bad taste in his mouth.
Constants and variables, we'd start there.
Soulmates. They were a rare phenomenon. Babies born with clocks on their wrists ~ nobody knew where it came from. Quirks were different, they could be dissected through scientific expression and study; a simple mutation with a meaning behind it. It was strange but explainable. But soulmates - Soulmates were different. People being drawn to each other. Pairs being born at two different sides of the world just to inevitably meet in the middle. Destiny had become an art form, a physical aspect of life! But only for some.
0.01% of the population. That's 800,000 out of 7 billion and he just happened to know two pairs of them. His best friend and his grandparents.
He knew It wasn't totally uncommon to initially refuse your soulmate, his grandfather was a prime example of that. No one wants to be tied down to someone at such a young age. Being told that you'll have to spend the rest of your life with a complete stranger? Anybody would say the idea was, at the very least, objectionable. He and Ganny hated each other for a while, I remember. But they kept being pulled together. Like a rubber band that snapped back whenever they stretched too far. Pops even tried to leave Japan at one point. But then his sister got sick and he had to travel back. He and gran bumped into each other at the hospital that day. Her cousin had broken his leg and stayed a room over. It was as if the harder they tried to run from each other, the more they were pulled together. Something would always happen. Something would always make their bond stronger.
Constant.
But no matter how true that was, people had the right to feel the way they wanted to feel. Bakugou was a little sharp around the edges and as upsetting as it is to say - it's not hard to initially not like him. He remembered being a little agitated when he told him how he managed those scars on his fingers.
"Oh my g- Have you never talked to a girl before?! You don't touch them without their permission, bro. That's like the first rule of manliness! You can't break the first rule of manliness!!"
"Fuck off, alright. I get that."
"Do you?!"
He had his vices.
But underneath that, he was truly a great guy. His passion was what pulled him in to the explosive blonde. His resolve, his indomitability. He was, without mention of his previous actions, the epitome of manliness. Being manly was not backing down. Being manly was putting your all into achieving your goals, and from the display he had been offered in the locker rooms, being manly was letting yourself be vulnerable. He was capable of being vulnerable. He cared about things ~ even if a little too much. He could see the error in his ways and feel regret for them. Or from what he'd seen, downright degradation. He cared about that girl. He cared about the way she saw him. He cared so much that he even let himself suffer, even if that meant letting her be happy with the man she wanted.
"I told her she could be with that fucking loser. I just...I didn't want her to hate me any more than she already did. I fucking-.... I let her go. Why did I- fuck!"
He was a better man than all of us.
And he wished she knew that. He wished she could see what he saw. I mean, she saw something at least. They were friends. She was making the steps to reach out to him beside their current situation. But he knew that was all he'd get from her. Friendship. And in a sense that was cruel. Having him be so close yet so far. Sitting on the opposing sides of a glass wall. Falling in love with what could have been but never was. Constantly toying with the idea of "What if?" It was her choice and he'd respect that. Even if it didn't seem like the right one.
Variables.
Midoriya, as great as a guy he was, was temporary.
Don't get him wrong, he had no quarrel with his freckled faced classmate. If anything, they were friends. He was reliable ~ determined. He knew that for sure after that camping incident. How he pulled through after Bakugou's kidnapping. She wasn't wrong for finding him romantically interesting. Especially when they seemed to click so well. They made a cute pair, a sweet one. But she was already destined for another. And as much as the two seemed to be right for each other, it was undeniable that Bakugou and (Y/N), even in the lowest era's of their relationship, fit in a much more intimate way.
He remembered watching them fight together from the surveillance deck outside the simulation field. How amazing they were going against the rest of his classmates. How coordinated they were without even trying to be. They were an unstoppable force. Waves enraged by tectonic plates, coming down like a tsunami of smoke and fire. It was a waltz for them, a slow dance as they swayed accordingly. They radiated predominance. Two halves that completed something unrivaled. Something that said "We are number one."
She was his and he was hers. Anybody could see that.
And both of them knew that deep down, even if not outright. They'd come around. Just like his grandparents did. Just like every soulmate does. You can only live off half a soul for so long, and when the facts were there, they were meant for each other, in more ways than one.
Let's just hope Bakugou can last the wait.
He stayed with his friend for the walk home after that. Waiting patiently at his locker while he grabbed his things. They hadn't talked much since their descent from the locker rooms. The silence between them empty and dismal. We'll talk when he's ready. He decided. That was a lot to unload in one sitting and he probably needs the time to regroup. But I'll be here for him when he does. Bros don't let bros suffer alone.
He made sure his footsteps matched his on their stride down the empty hallway. Making certain to be a good distance to be sure he didn't feel too crowded but not far enough to seem like he wasn't walking with him. He wanted to be extra careful. The closest he had ever come to seeing his friend this distraught was when he let him help patch him up that one time, after that fight he had with Midoriya. But that was nothing like this. No, that was cake compared to what had happened just now. His guilt over All Might's retirement was nothing compared to the despair that came with losing a part of you. Seeing half of your soul refuse to be completed and knowing that may have actually been your fault. He couldn't imagine it. The emotional agony that came with something like that. He'd break if that were him. He admired Bakugou's strength in this situation.
Kirishima pushed himself into the handle on the stairway door, leaning into it to let his friend walk in first.
He paused before starting down the steps.
Giggling. Someone was giggling.
No. Not just someone.
He could hear Bakugou's breath audible hitch beside him. He moved before he could. "Um I'm gonna go... check that out. You stay here."
Before he could even open his mouth to object he was already halfway down the stairs. His feet scurrying in a brisk tiptoe as he tried to keep himself silent. He was dreading whatever was happening at the bottom of these steps. This wasn't good. They should have left like twenty minutes ago. That giggling sounded too content. God, he hoped that weren't doing what he thought they were.
His ears perked when he nearly finished the last step.
"Izuku..ah..stop.." She whined.
He chuckled. "Why?"
"Because...we're not supposed to be doing this here. Besides~ mh... This isn't talking."
"We're talking now aren't we?" His laugh came out a little muffled that time.
"That's not-" She choked back a whimper. "..What I meant."
Kirishima took a deep breath before he bit the bullet and turned the corner. This was so fucked up.
At least it wasn't what he was expected. Entirely that is.
He had her pinned against the wall, his hands disappearing under her skirt as he held her up by her upper thighs. There was no penetrating which thank fuck. But he was basically rutting himself into her. His head tilted to be partially shaded by her jaw, his mouth latched on to the skin on her neck. He could see that lavaliere of bruises she sported from where he was standing. Deep purples spilling down her collar bone and onto the top of her breasts where her shirt had been unbuttoned. Baby pink lace turning white in the sun rays that leaked through the glass on the exit door.
There were two emotions that struck him in that moment. Embarrassment. He felt a little perverted, to be honest. Seeing (Y/N) like this made him feel like he was breaking the bro code. Like peeping on your best friend's girlfriend when she's getting dressed. Except now, it was his best friend's soulmate and he was watching her be all but dry fucked by some other guy.
And anger.
Because somehow.
In some way.
He knew,
That Midoriya had planned this.
And that made him furious.
Hardening the hand closest to the wall, he slammed his fist into the brick with a hard clack! His knuckles somewhat breaking into the material and forcing the two to jump in response.
The surprise that sombered over shame as she looked over at him was enough to make him feel a little bad. But the confusion that spiked into irritation on her boyfriend's face only infuriated him more. That was it. He knew. He was supposed to be Bakugou. And then what? Was he hoping he'd blow up in his face? Evoke a reaction? Was he deliberately trying to hurt him? What was his game? What was his fucking problem?!
(Y/N) gently pushed at Midoriya's chest as she climbed out of his grasp. Quickly reaching for her buttons to cover up her partially exposed chest. Her face twisted with embarrassment and affliction, she opened her mouth to speak but didn't get the chance to.
Kirishima was yanking Midoriya by his collar within that second. His calcified knuckles raised high and ready to come down. He wanted to bash his skull in. Of all the slimy fucking scum. "What the fuck is wrong with you, man?! Huh?! What the fuck is your problem?!"
"Kirishima? What ~ What the hell are you doing?!"
He didn't even move to look at her. His eyes were stuck on the equally as unwavering and agitated ones shooting right back him. "You're a real fucking scumbag you know that?"
"Let me go, Kirishima." It sounded like a threat. What the fuck.
He was gonna let him have it. He was gonna knock his goddamn lights out and deal with the repercussions later. He was irate right now. To do something like this to another person? Heroes weren't like that. This was villainous behavior ~ downright diabolical. And the absolute animosity in his eyes. - He was lifting his hand. He was going to hit him. He dared him to.
"What the fuck is going on?"
The sound of his voice startled the three of them, their attention pulled over to his place on the steps.
He looked irritated. Not hurt. Not angry. But irritated. He must've just stumbled upon the scene. Thank god.
Kirishima brought his gaze back to Midoriya before glancing at his equally as irritated steady. That was good too. Either it be from earlier or what was about to transpire, her dissatisfaction had risen to a mane of smoke on her head and shoulders. Covering the bruises on her neck from where he was standing, and her shirt buttoned to conceal what was left. He saw nothing. Thank fucking god.
Kirishima shoved the boy back as he deactivated his quirk. Moving backwards toward the exit door. "Nothing." He snarled. "We were just leaving."
Bakugou stared at the three for a moment. His eyes lingering on his mate's before being forcibly pulled away by the turn of her head. He let out a distrustful huff. "Sure."
Kirishima held the door open as he made his way down the steps, meeting (Y/N)'s eyes as he walked passed him.
"Talk to you later, (Y/N)." It was chastising, but a promise.
She looked away as he finally turned to leave. She felt guilty. She didn't know why. But she did and it made her a little sick inside.
She couldn't help but feel glad he didn't see what had happened.
