A/N: Hello yes I am bad at writing. I know I said I'd write a gay harem but I'd like our readers to ease into it so I thought I'd start with some good ol' tsundere. Please forgive me, Kaachan. Also sorry if he's a lil OOC. I've nevr written for Bakugou before.

Quirk: Siren.

Allows the user to sing a song that sounds sweet, but is actually a frequency that allows the user to control someone's mind and actions for 10-30 minutes, depending on how loud they sing and how big the subject is. This works best on the user's opposite gender but can be used on any living thing. It also allows the user to swim more easily and breathe underwater. The drawbacks include the user constantly having a sore throat/raspy voice and fish-like qualities. The user has larger eyes, gills, patterned scales on parts of their bodies (koi scales 'cause aesthetic) and those weird webbed fish ears I don't know how to describe.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Katsuki Bakugou. Out of everyone in 1-A, you just had to be in a friend group with the one guy who manages to despise every aspect of your being. Every other student in the class is just fine with your existence, but Bakugou somehow came to the conclusion that your very presence brings dishonour to his name... somehow. Every time you pass in the halls he comments on something. He did this so often you managed to keep a collection.

"Pull your skirt down. No one wants to see your scaley legs."

"I smell rotten tuna. (Y/N) must be here."

"And what are you gonna do? Glub at me?"

"Tch. Lose some weight, whale."

"Oh, look! Everyone's favorite blobfish!"

These interactions would usually end with either Kaminari or Kirishima giving you a sympathetic smile and a fleeting head pat before you went your separate ways.

It was horrible, having him insult the very thing you stressed about constantly. But the keyword here is was. He had been doing it for so long that you began to realize your growing resilience towards his insults. And now you were no longer affected. Instead, you used him as a stepping stone of sorts, a way to lessen the effect of the insults you'd sometimes receive.

But this time... he'd gone too far. As you sat there, crying into Kirishima's shoulder, you wondered what about your new hero suit had offended him so much that he decided to call it a 'disgusting rag with a fishy whore in it'. It wouldn't have affected you as much if you hadn't spent weeks modifying it with Mina and Ochaco, making it sure it embodied your quirk and complimented your physical features. You were ready to upgrade from the clunky garment you had before to something a little more revealing to show off your new-found confidence, but apparently Bakugou disagreed with this notion.

He didn't realize it would upset you this much. If he did, he wouldn't have said it. he thought you'd just brush it off as you did with everything else he said. But he'd pushed it. He never really meant it. In fact, he never really meant anything he said. But he knew if he started being nice to you, everyone would catch on fairly quickly. And that could not happen. He'd upset you too much. He'd blown any chance he had.

The next day, he was exiled from the 'Bakusquad'. His former friends scowled at him while he sauntered to an empty table to eat his lunch. No one spoke to him. They knew the sort of state he was in. If they said the wrong thing, which could be anything, they'd be sent straight to recovery girl with a missing arm. But they couldn't help but notice how much he glanced over at you. No. Glanced was the wrong word. More like glared, and specifically at the muscular redhead next to you.

Katsuki hated how close you and Kirishima were after the incident. He loathed how much more genuine your smile was towards him. It made his blood boil when you clung onto Kiri's arm whenever he passed by your desk. The way he smiled so cheerfully when you sang to him, making a ladybug loop around his head was excruciating. And he wanted to rip the poor boy's head off when he made the unforgivable mistake of asking you on a date, which you happily accepted. Watching you two cuddle after training was agonizing. He had never been filled with such unrelenting anger towards an innocent human being. So he decided to do something about it.

"What do you want, Katsuki?" He could hear the venom in your voice. "I've got a date with Eijiro in ten minutes. Not that you would care." Your voice was slightly hoarse.

"Will you just shut up and listen to me? I've got something to tell you, asshole." Bakugou turned his head to face the ground beside you. Making eye contact made his face burn with embarrassment.

"Are you here to tell me how much of a slut I look in this dress or somethi-"

"No! Just... just stop talking for a minute, ok? This is important." His voice lowered in volume, something you thought impossible for him. You stayed silent, waiting for him to continue. He took a deep breath.

"Look, I wanted to say sorry. I know I've treated you like shit since them moment I met you, but... can you just, like, forget all that for a second while I tell you the next part?" Your eyes went wide. Katsuki Bakugou was apologizing? To you? This was unheard of. You couldn't form a coherent sentence, so you just nodded and waited for this elusive 'second part'.

He took an even bigger gulp of air and placed his hand on your shoulder.

"I... like you. I have done for a long time. I was going to tell you but... I didn't want to be seen as weak. I didn't want you to be seen as weak. I thought having feelings like that meant I wasn't strong enough, so I tried to force them away by convincing myself to hate you. But I could never quite manage it. And... I don't want you to feel pressured into liking me back. Especially since you're dating Kiri. If you still hate me, that's fine. But... can you let me down easy?"

Neither of you spoke. The only sound you could hear was the thumping of your heart against your ribcage. You took a tentative step forward. This had to be a joke, right? Stuff like this only happened in shitty anime fanfics. You waited for him to laugh. Nothing.

"I... uh... I like you too... I never said anything because... I thought you hated me. I guess not." You gently grabbed his hand smiling, only to get the breath knocked out of you by Katsuki's bone-crushing hug.

"T-thanks. Nerd. I r-really needed that." He started sobbing into your shoulder. The best you could do was rub his back as comfortingly as you could. It seemed to work, as he calmed down rather quickly. "H-hey," he said, still sniffling, "Could you...s-sing for me?"

You began to hum a soft melody, beckoning forth a group of wandering butterflies that swerved in between each other like dancers. Peace seemed to fall over the area as the two of you leaned against a wall, silently enjoying each other's company as the delicate tune left your lips.

Unfortunately, this was interrupted by a sudden: "WOOOOOOOOOO! DENKI, YOU OWE ME 10000 YEN! I TOLD YOU HE'D DO IT!" This was the unmistakable voice of Kirishima, followed by the sorrowful wails of Kaminari, wondering why on earth he bet 10000 yen.

"Wait... weren't you two dating?" Katsuki asked, now confused.

"We were. He found out about you liking me last week when he heard you at the gym. You were saying something about getting stronger for me? Anyway, Denki bet him you were doing it to mess with us so we decided to end things there incase you... y'know. Did it. And you... y'know. Did it."

"Which is why I give you my formal permission to date Koi-chan!"

"Are you ever going to stop with the nicknames, Kiri?"

"Absolutely not!"

You sighed and turned to Bakugou. You could tell he was thinking the same thing.

"So... wanna go out some time?" You already knew the answer.

"Hell yeah, I do!" he laned his face closer to yours, "My little Koi fish."
