Easy to approach. Steady in a way that made people trust him without thinking twice.\n\nKatsuki Bakugo—loud, sharp, confident to the point of arrogance. Strong, explosive, and fully aware of it.\n\nSo when people learned Katsuki was an omega and Izuku an alpha?\n\nYeah. That threw them off.\n\n—\n\nMiddle school had been rough. There wasn’t much else to say about it. Too many sharp words, too much pride, too many things neither of them knew how to handle back then.\n\nHigh school was different. They changed.\n\nSomewhere along the way, arguments turned into conversations. Distance turned into something closer. Training together turned into choosing to be around each other. They became… easy.\n\nNot in a boring way. Nothing about them was ever quiet or simple—but there was an understanding there. A rhythm. They knew how to exist around each other without forcing it.\n\nBest friends. Maybe more. Neither of them said it out loud. Didn’t need to.\n\n—\n\nThey also had one thing in common. They both hated second genders.\n\nTo them, it was just another way to box people in. Another excuse for expectations, stereotypes, limits.\n\nIzuku didn’t like how it made people underestimate others.\n\nKatsuki hated it for a different reason.\n\n—\n\nKatsuki despised being an omega.\n\nPeople expected him to be soft. Submissive. Quiet. Weak It was insulting.\n\nEvery look, every assumption, every time someone hesitated around him like he was fragile—it got under his skin. He worked twice as hard just to prove them wrong. Louder, stronger, better.\n\nNo one was going to reduce him to something he wasn’t. Not ever.\n\n—\n\nWhich made this even worse. Katsuki woke up feeling wrong. Hot.\n\nNot the normal kind—this was deeper. Heavy. Sitting under his skin like something was building, something he couldn’t just burn off in training or ignore.\n\nHe sat up slowly, jaw tightening as the feeling settled in. “…You’ve gotta be kidding me.”\n\nHeat. Great. Perfect timing.\n\nHis body felt off—too sensitive, too aware. Even the air felt different. Annoying. Distracting. His thoughts wouldn’t settle, irritation bubbling up faster than usual. Katsuki clicked his tongue, dragging a hand down his face.\n\n“Stupid,” he muttered.\n\nHe wasn’t going to school like this. No way.\n\n—\n\nIzuku noticed immediately. Katsuki never skipped. Not training. Not class. Not anything.\n\nSo when his seat stayed empty the entire morning, something in Izuku’s chest tightened.\n\nBy lunch, he wasn’t even pretending to focus anymore. By the end of the day—He was already running.\n\n—\n\nKatsuki’s dorm door didn’t open right away.\n\nIzuku knocked again, more urgently this time. “Kacchan?”\n\nA pause.\n\nThen the door cracked open just slightly. And that was all it took. Izuku froze.\n\nKatsuki’s scent hit him first—stronger than usual, heavy in a way that made Izuku’s instincts flare before his brain caught up. His face was flushed, eyes sharper, more unfocused than normal, like he was fighting something internal.\n\n“…You’re in heat,” Izuku said quietly.\n\nKatsuki’s eye twitched. “No shit.”\n\nHe looked irritated—more than usual—but there was something else under it. Tension. Discomfort he clearly wasn’t used to.\n\nIzuku’s expression shifted immediately. Concern. Focus. “Did you take anything?” he asked, already stepping closer despite himself.\n\n“I’m fine,” Katsuki snapped.\n\nHe wasn’t. Izuku could tell. The way he was standing—too rigid. The way his breathing wasn’t steady. The way his scent kept spiking like it was out of his control.\n\nThis wasn’t something Katsuki handled often. Or at least—not like this.\n\nIzuku hesitated for half a second. Then made a decision. “I’m coming in,” he said.\n\nKatsuki didn’t argue. Didn’t move either. He just stepped back enough to let him. And that alone said more than anything else could.\n\nBecause Katsuki didn’t let people see him like this.\n\nBut Izuku? Izuku was different. And now they had something new to deal with.
