There are two things in the world that define you: your quirk and your secondary gender.

Katsuki Bakugou knew he was destined for greatness, that he was going to be the future #1 Hero, that he would surpass even the brilliance that was All Might.

He knew this the second small little explosions /pop popped/ from his hands. Knew it the second the other students in his class crowded around him to get a better look.

Knew the moment his teacher called him amazing.

Truthfully, Katsuki didn't care all that much what his secondary gender was. Whether Omega or Alpha, neither will stop him from completing his goal. Not when he has a quirk like his.

And what did it matter, if he had a knot or slick? As long as he wasn't a-

"So the test came back as Beta."

Katsuki was 16 years old, sat in a small black chair, he had stared straight ahead as his mom and doctor talked about what he expect from his presentation. It all sounds like nonsense to Katsuki, like there is water in his ears.

The words had washed over him, nothing coming through besides "Beta, Beta, You're a /Beta/."

Less than 20% of the world were Betas. Generally speaking, you were either an Omega or an Alpha.

/That/ was the norm.

/That/ is what Katsuki expected. Not this...

Not this.../failure/.

"Kacchan, are you ok?"

Katsuki jolts, knocked from where he had been staring into space, memories of that day floating away.

Quickly, he looks down, stirring his pan, food sizzling as he makes breakfast. "Yeah, nerd. Everything is fine."

Izuku Midoriya- /Deku/- stares at him from the hallway, looking like he has just woken up. He's in an oversized shirt, obviously not his, which covers his frame, hanging just above his knees.

He's not wearing any bottoms.

Katsuki keeps his eyes on the pan.

"...if you're sure?"

"I'm /sure/," Katsuki says. He can't help but roll his eyes. "Nothing for you to worry about anyways."

"Now, see, you can't say that. Everything being fine and it not concerning me are two /very/ different things."

"Do you want fucking breakfast or not?"

"And now you're deflecting."

Katsuki narrows, but Deku has long since gotten over any fear of him. So instead, he slaps his spatula against the calendar that sits attached to the fridge. "Don't you have more important things to worry about?"

Deku's eyes follow, going wide at the red lines that dot the week. "Oh jeez, is it already that time again?"

Katsuki snorts. "How is it that I keep better track of your heats than you do?"

"It's probably /because/ you keep track of them that he doesn't," a new voice says. Eijirou Kirishima walks into the kitchen, coming up right behind Deku to wrap him in a hug, brushing his nose against the other. He is only wearing sweatpants, his abs bare to the world.

Once again, Katsuki looks away.

"Hey, babe," Izuku says, leaning up to get a kiss. Deku was tall, especially for an Omega, but he has nothing on Eijirou's towering height. Eijirou practically dwarfed Katsuki, who was even shorter than Deku.

A Beta. Shorter than an Omega.

"Are you ok?" Eijirou asks and Katsuki jolts once again, not realizing his mind had started to drift. Eijirou and Deku are looking at him, both frowning.

"Yes, fuck. You two are such assholes," Katsuki says. He shuts off the stove and begins to divide up the food into three bowls.

"You've been...staring a lot more, eyes going blank. As if your mind is far away," Deku ventures. "And you've been quiet. It's not like you, Kacchan."

Katsuki sighs. He sets the bowls on the table. Deku gets the silverware. Eijirou gets the cups and kettle of tea. Once they have the table set up, and they had all settled down, Katsuki speaks up again.

"I'm just thinking through some stuff. It's nothing concerning you guys. I'll be fine. Don't stress yourself so much."

Eijirou and Deku share a look. Katsuki's stomach violently swirls and his chest tightens. He knows that look. Hates it.

Fucking /pity/.

"This is about your asshole ex-boyfriend, right?" Eijirou takes a stab at guessing.

Katsuki pulls his lips over his teeth at just the mention of /him./

His boyfriend of almost a year had up and decided that Katsuki being a neat freak was /suddenly/ a problem, enough to break up with him over.

Katsuki suspects it has more to do with the Omega he's now seeing.

Not that it matters, the root of the problem stays the same. Katsuki wasn't good enough.

Because he was a /Beta/.

But he wasn't about to complain to the boy he used to give shit for being quirkless. For the hundredth time, Katsuki wonders if this is karma.

No, he thinks, eyeing the way Eijirou feeds Deku a bit of his food. The real karma was catching feelings for the damn nerd /and/ his mate while forced to live with them.

"Like I said," Katsuki says, a bit more forcefully. "I'm working through it."

Deku looks like he wants to say more but Eijirou places a hand on his arm. "Of course, Katsuki. We'll give you space."

"Good. Now fucking eat up before the food gets fucking cold."

"Yes, sir," the two say, the smartasses even saluting him, before digging in.
