Chapter Text
Aizawa watched Bakugou’s expression change as his words began to sink in. This was not how he had wanted to tell him about the pregnancy. He’d been running through different scenarios in his head since he’d found out three days ago. They ranged from the idea of taking him out for a nice dinner and dropping the news there, to sending him a quick text and then blocking him to flee the country with Eri in tow.
He really should have gone through with the nice dinner. He was full of dick, half undressed, and starting to get hungry. On top of all that, it was getting late, and he now had to have a conversation he’d been avoiding. Wasn’t there a greeting card for this situation, something that said ‘thanks for knocking me up, but I’m still afraid you’re going to decide this was too much, and leave.’
And if all of THAT wasn’t enough, his omega instincts were going haywire because once again, Katsuki smelled like another omega. By now, Aizawa could easily pick up on the scents of the different omegas that he worked with. But this one was familiar in a different way. If he didn’t know better, he’d say he smelled like another former student. But that was impossible. He’d lost touch with Shinsou over a year ago now, and as far as he knew, he wasn’t even in the country.
“You let me fuck you like that, and you’re pregnant?” The first words out of Katsuki’s mouth were as ridiculous as this entire situation.
“I don’t automatically turn into something fragile as soon as you breed me, Katsuki. I’m fine.”
“I was rougher than usual. I barely even warmed you up.” Katsuki touched his thighs with gentle hands, as if to apologize. There was no apology needed. Aizawa was the one who had been holding back, who should be saying sorry to his mate. What kind of omega was he, that he hadn’t called his alpha with the news from the doctor’s office immediately, overjoyed as he should have been.
“I’m fine.”
“You always say you’re fine. When did you find out? Did you see a doctor already? Does anyone else know?”
“A few days ago, and yes, I found out at the doctor’s office. I don’t need to go back for another month. You’re the first person I told.”
“Omega…” Katsuki shifted until he could sit up, holding Aizawa closer to him in his lap, knot still firmly inside of him. “I’m not going anywhere.”
More reassurance. More promises, and he hadn’t broken one yet. Aizawa told himself that, over and over.
“We’re gonna have a baby,” Katsuki continued, sounding thoughtful. Then, triumphant, “We did it.”
“Don’t tell anyone else yet. Please.”
“Yeah, okay. Whatever you want. I’m gonna take care of you, so don’t worry. You, Eri, the baby–don’t worry about anything, okay?”
Aizawa let himself be held there, his mussed hair sticking to his face where it was pressed against Katsuki’s chest. He hadn’t really processed the pregnancy himself. A part of him had thought that it wouldn’t happen, that he had wasted too much time and it was too late. He’d been hoping for years that he’d have the opportunity to have a baby, and now it was really happening. He was currently feeling the most vulnerable he’d ever felt in his entire life. He should be feeling happy, shouldn’t he?
His stomach rumbled.
“Did you eat dinner?” Katsuki asked, rubbing his back with one broad hand.
“I–oh. Eri had dinner in one of the student kitchens. I got distracted grading.”
“Let’s clean up and I’ll make you something. It’s late.”
As much as Aizawa wanted to ignore his stomach and go curl up in his nest without any hassle, he let Katsuki serve them both up a simple dinner.
“I didn’t get a chance to eat much earlier either,” he admitted, sitting down across from Aizawa at the kotatsu. Despite putting everything together in the short time while Aizawa had cleaned up in the bathroom, there were still vegetable side dishes to go along with the rice and fish, and the miso soup Katsuki placed in front of Aizawa was steaming hot. Of course a lot had been leftover from the last time Katsuki had cooked, but even keeping track of that sort of thing was a skill that Aizawa had never seemed to manage on his own.
“I’d like you to come with me for my next doctor’s appointment,” Aizawa offered.
“Yeah?” Katsuki’s face lit up, and set his chopsticks down. “A month, right? Send me the date, I’ll be there.”

The thing about being back home, is that eventually you were bound to run into someone you knew on the street. Traveling as he had, Shinsou could now recognize how small Musutafu actually was. So it was with a sort of heavy inevitability that he made the choice not to cross the street when he saw his former sensei walking towards him.
He saw the moment that Yamada Hizashi picked him out of the crowd. His step faltered, and the friendly smile he usually wore faded for a split second before coming back in full, although this time it seemed somewhat forced. Shinsou braced himself for whatever greeting Yamada might think was appropriate for a former student who had been close with his omega.
“Hey, Hitoshi! Is that you?” Yamada clapped him on the back when he got close enough without waiting for an answer. “No way, you can’t be the same kid. You’re all muscle now!”
“Yamada sensei. Good to see you.”
Yamada pulled them to the side of the street, away from the main foot traffic, keeping their arms linked.
“Well, what brings you back, kiddo? Last I heard, you were working an ocean away.”
“More or less.”
“Wow, you’re really talking my ear off. I can’t get a word in edgewise with you.” He took the opportunity to stand back and look Shinsou up and down. It was true, Shinsou had filled out his frame with muscle, and while Yamada still had an inch or two in height on him, he was still the same beanpole he’d always been. Not that it mattered. When it came down to it, Yamada was an alpha and Aizawa’s mate, and Shinsou was only an omega.
“I thought I might stop by U.A. once I’ve settled back in here,” Shinsou offered reluctantly. There wasn’t any particular reason that Yamada shouldn’t know that, nothing except the old jealousy eating away at his heart like corrosion on a battery.
“Ah, of course! Everyone would love to see you. It’s always great to have an old student visit, especially one as successful as you.”
The word ‘successful’ flitted around Shinsou’s mind for a few moments before he decided it was ultimately unhelpful to dwell on that. He wasn’t sure what he would consider success at this point. Was he very, very good at what he did? Of course. That would have to be enough for now. His mentor’s voice spoke up that he’d saved people, he’d done his job many times over. And Aizawa was never a fan of him having a pity party for himself.
Shinsou decided to bite the bullet and simply ask what he wanted to know.
“How’s Aizawa sensei? Is he well?”
“Oh! Ah…Well. Well!” Yamada stuttered, as if the question stumped him. “From what I’ve heard, he’s well.”
Shinsou narrowed his eyes at the flailing blond in front of him. “You’ve heard?”
He sniffed the air around Yamada, reaching back in his scent memory for any hint of Aizawa. There was none.
“He stopped seeing me a little while ago. I tried to talk sense into him, but. Well, you’ll see for yourself. You would expect some loyalty after all those years we had together! Kind of a whore move if you ask me–”
"Don’t."
Whoever said omegas couldn’t growl, had never heard an omega full of protective rage when his former mentor was being bad mouthed in public right in front of him. Yamada’s eyes went wide, and it wasn’t wishful thinking that there was fear there. Shinsou had seen that look too many times by now to think it was anything else.
“I would think very carefully about what you’re going to say next,” Shinsou said. Only the extensive training he’d received on the job was keeping his body from acting on its own and taking a swing at the other man. There were more than a few ways he could think of to incapacitate him, and only a couple of them involved his quirk. But he didn’t have a spotless agency record for nothing. He couldn’t throw that away simply because he wanted to defend Aizawa’s honor.
“Look,” Yamada said, putting his hands up in a placating manner. “Clearly I upset you. I should have known you wouldn’t want to hear anything like that about him.”
“Did you hurt him?”
“I wanted to work things out.” Yamada shrugged. “See for yourself who he’s shacking up with. I gotta go, kid. See ya around.”
Shinsou barely registered Yamada leaving, his mind now whirling with the possibility that Aizawa now had someone new. Aizawa had left his alpha, and Shinsou hadn’t been there. What kind of dinner did one get to wallow in the misery of missed opportunities? Onigiri on a rooftop sounded like the sort of thing that the situation called for. At least then, he’d be in plain sight if the universe wanted to laugh in his face some more.
