Chapter Text
“This can’t be right…” Katsuki whispered to himself as he opened the results of his medical exam.
Every first year is required to take one upon getting into the U.A. The documents contained the standard stuff, allergies, weight, height. However, they also tested for something else. Your second gender.
And Katsuki had just found his out. Saying it was unexpected is an understatement.
You see, Katsuki Bakugou had always been the loudest, the most rebellious, the most dominant, boy out of all his peers. He was the strongest, and in his mind, that meant dom.
But as Bakugou scanned his results, his eyes clung to one word in the middle of the page, bright red as if mocking him. Sub.
He was a sub. A submissive, obedient, baby dick with no control anymore. How could that be? Katsuki Bakugou? A sub?
“Bakugou” Mr. Aizawa’s voice called out.
“What?” Bakugou scowled back, tearing his eyes from the page and turning it over, results hidden from the rest of the class.
“Watch your tone. And see me after class” Mr. Aizawa said, going back to helping another extra.
Bakugou sat there for another ten minutes before the bell rang. He turned over the bright red letters in his mind because surely they made some kind of mistake. Surely this was all a big misunderstanding.
Once the rest of the class had filed out of the room, Bakugou remained seated, propping his legs up on an adjacent desk.
“Bakugou” Mr. Aizawa said, returning to the front of the room after shutting the doors.
“Yes, Mr. Aizawa?” Katsuki got out, trying his best to keep his voice even and smooth.
“Did you see your results?” Aizawa asked, sitting behind his desk and typing something onto his computer.
“Yes” Bakugou managed curtly.
“They weren’t what you were expecting, I assume” Mr. Aizawa concluded.
“Not at all,” Bakugou admitted. “There’s got to be some kind of mistake! I’m not-” he started.
“Not what?” Aizawa looked up. “Not a sub? Our medical professionals have been doing this for years, they don’t mess up these results. You are a sub” Mr. Aizawa said, trying his best to get the child used to the idea.
“That’s not what I wanted to talk to you about though” Mr. Aizawa continued.
“It’s not?” Bakugou looked up, intrigued.
“No. There’s something else” Aizawa said, pulling up a document on his computer and beckoning his student over.
Bakugou got up to see a chart, his medical chart to be specific.
“What is that?” he squinted, trying to interpret the data.
“Those are your hormone levels,” Aizawa told him. “The blue line is the average level for a sub, and the red line is yours,” he said, pointing to the corresponding line.
Bakugou took a moment to comprehend the information before speaking again.
“Why are mine so much higher?”
“This is what I wanted to talk to you about. Your hormone levels are anomalies. Subs usually can manage their hormones with medication or other outlets but you’re a special case” Mr. Aizawa explained.
“How special?” Bakugou urged, wanting this conversation to be over.
“Your levels are so high that medication would only bring them down to a little below that of an average subs. Additionally, subs with levels as high as yours have a higher chance of being Littles” Aizawa said.
“Littles?” Bakugou asked. He’d heard about how some people pretend their babies, but he didn’t really know what it all meant.
“A little is someone who sometimes age regresses as a response to an external situation. The reason subs with high hormone levels are more likely to be littles is because you are in need of even more care and supervision then regular subs” Aizawa went on.
“So you’re saying I’m a little?” Bakugou asked, the anger rising in him.
“I’m saying we don’t know. We’ve contacted your parents so tomorrow afternoon you’ll be undergoing a psychological evaluation so we can determine if you are or aren’t one” Aizawa stated.
“Well what happens if I am one?” Bakugou questioned, a little tremor in his voice.
“We’ll cross that bridge when we get there,” Aizawa reassured him. “For now, head back to the dorms. We’re all done for today” Aizawa said, getting up and packing his stuff.
As the two headed to the door, Bakugou swiftly turned to Aizawa to ask him something.
“Mr. Aizawa?” Bakugou said, less confidence in his voice than usual.
“Yes?” Aizawa turned to him as well.
“Can you keep this a secret? The whole sub thing. I don’t want the rest of the class to know” Bakugou said, his face red with embarrassment but held high nonetheless.
“Of course, Bakugou. We have other subs but I won’t go around telling anyone about you” Aizawa comforted him.
“Thank you, sir” Bakugou said, before briskly walking past him so he could forget the conversation ever happened.
