Aizawa walks into the classroom on Monday, and is met with one hell of a scene.

He shouldn't be surprised. He really shouldn't. But he freezes at the sight anyway, before sighing all of his disappointment to the two standing right in the middle of it all.

"Bakugo, Kaminari, detention this afternoon."

"What!" Kaminari argued, "what did I do!!"

"For a week."

Kaminari's eyes widened in panic.

"Wait no! No don't do-" he was cut off by Bakugo slamming his hand over his mouth, and for a second, the class sat in silence, watching as Mr Aizawa stared at the two piercingly, taking a moment to think.

"A month."

"Now look what you've done dunce face!" Bakugo hissed in his ear.

"Bakugo let go of Kaminari before I make it longer," Aizawa said tiredly, and Bakugo practically threw Kaminari towards his desk, before going down to sit at his own, grumbling about 'shitty dunce face getting him way too fucking much shitty detention'.

The class dispersed, away from the giant mess that had been caused.

"You two can spend this afternoon cleaning that up. But for now, we'll get on with class."

Kaminari groaned into his desk quietly. He didn't want detention. Nonetheless for a month. Nonetheless with Bakugo.

Even if they weren't weirdly estranged soulmates, being the reason that Bakugo had extra detention was never exactly on his bucket list.

"Woooow, hi Kacchan, funny seeing you here?" Kaminari laughed hesitantly, stepping into the classroom for his detention.

"Shut the fuck up dunce face before I blast your ass to hell," Bakugo growled threateningly from his desk.

"Oookay then," Kaminari sat in a desk as far as physically possible from Bakugo, and they sat in silence for a minute.

Kaminari was about to open his mouth and ask where Aizawa was, when he appeared in the doorway.

"You have to stay here for an hour. You won't be able to leave. I'm not kidding don't even try, there's a quirk. Do your homework or something. No talking."

Then he turned on his heel and left again.

Kaminari sighed and pulled his homework out of his bag. Might as well make the most of this and get some shit done.

"Bakugo! You're back!" Kirishima called out from his spot on the couch next to Mina. "How was detention?!"

"Just as shitty as it sounds like," Bakugo complained, flopping on the couch next to Kiri. "Got some homework done though."

"Are you still helping me out with maths?"

"Of course shitty hair, what else would I do to waste away my afternoon?" Bakugo responded in a sarcastic tone.

"Man that's a bit mean," Kiri responded, a little bit hurt, and still unsure of whether Bakugo was going to tutor him or not.

Bakugo, however, noticed this, and seemed to hesitate.

"Sorry," he said quickly, before grabbing Kirishima by the wrist. "I meant that you'll be coming to my room tonight to study."

Kirishima's face lit up.

"Really?! You'll let me into your room?!"

Bakugo rolled his eyes.

"Only you, Eijiro. Don't go inviting anyone else in."

"Yessir!" Kiri responded enthusiastically. "Also what's with the Eijiro?"

Bakugo sent him a side glance as they waited for the elevator to arrive.

"I didn't want to call you shitty hair anymore and Kirishima feels fucking weird to say, so figured Eijiro was fine. Is it not?"

Kirishima grinned.

"No it's fine..."

"Katsuki."

"WILL YOU STOP. FUCKING. ROCKING. ON. YOUR. CHAIR SHITTY DUNCE FACE."

The legs of Kamis chair clanged against the tiles of the floor loudly, louder than was probably necessary.

"I'm fucking bored Bakugo! What do you want me to do, sit silently and writhe in my emotions like you do?!"

"I do not writhe in my emotions, you shitty fuck munch."

"Then what do you do? All I see is you glaring intensely at a blank wall."

It was only day three of their detention, and they were already getting on each other's nerves.

Bakugo hated that Kaminari just could not sit still. All he wanted was for the hour and a half to be over and done with with as little interaction as possible, but it seemed it couldn't be that way.

Kaminari, on the other hand, needed constant stimulation. Being stuck in detention, well, didn't really do it for him. And Bakugo was tight as a clam when it came to talking, but his jaw seemed plenty loose when Kaminari found other things to waste his time on.

"I'LL DO WHAT I FUCKING WANT."

"Then I'll do what I fucking want too!" Kaminari yelled back. By now they were both standing up.

"WHAT YOU FUCKING WANT TO DO IS FUCKING ANNOYING."

"Yeah well-!" Kaminari stopped halfway through his sentence and froze.

"Fucking what is it dunce face."

"You're um-" he cleared his throat and gestured to his body, causing Bakugo to look at his hands.

Which were glowing bright yellow.

Bakugo groaned.

"Fucking hell," he mumbled, sitting back down in his seat 💺.

Kaminari sat back down as well, and kicked at the leg of his table, bored again.

"You know I really don't care right?" He prompted.

"About what."

"About all of this," he replied, flashing his soulmarks so Bakugo knew what he was talking about.

He saw Bakugo open his mouth to respond, but decided to interject before he could start.

"I mean, you have another soulmate and so do I. We don't need to bother about this dumb, extra thing that's happened for some reason."

"It's still there for a reason you idiotic fuckmunch."

Kaminari grimaced at the nickname, but continued anyway.

"So what? If worst comes to worst, we can figure it out when we're older."

There was a moment of silence, and Kaminari was starting to get worried that Bakugo was going to start arguing again. But the he surprised him.

"Who's your other soulmate?" He asked instead.

"Um-" Kaminari stuttered, caught off guard by the sudden small talk. "I don't actually know yet, but I still have lots of white covering my body, you know? Probably won't meet them till I'm older."

Bakugo nodded slowly, and Kaminari thought that was going to be the end of their awkward little conversation.

But it wasn't.

"I hope you get someone good," Bakugo said.

That was normal etiquette when talking about soulmates that you hadn't met. Although Kaminari had heard it said to others, and even said it hundreds of times himself, no one had ever said it to him.

And although everyone he'd ever seen responded with an eye roll, Kaminari smiled at that before replying.

"I hope so too."
