Chapter Text
Izuku fidgeted when he was nervous. So naturally, he couldn't stop drumming his pencil on his desk as he stared at the clock.
Kacchan was late. Kacchan was never late.
Oh god, what if he was pissed off? What if he'd ruined everything? What if Kacchan never talked to him again? What if—
"You okay, Deku?" Ochako asked, hovering over him. "You look like you're gonna throw up."
"Jury's out," he admitted absently.
"What's wrong?"
He just shook his head. He heard Ochako's huff of irritation but ignored it. The only person in class who knew what was happening was Momo, and that was just because he'd needed her help.
Everything had to go at Kacchan's pace, including telling their friends. He might be an omega, but he hated being perceived as soft or possessed. Izuku just wanted him. He didn't care what pace they went at. Kacchan would, though.
If he accepted him.
He'd be crushed if he didn't. But he'd get over it, as long as he'd tried.
Assuming Kacchan would ever look him in the eyes again.
Fuck, why did he decide to do this? It was too big a risk!
The door to the classroom slammed open, and Izuku's head snapped up to meet a burning red stare. Glaring—burning holes through him, really. In his experience, that glare meant that Kacchan was pissed.
Fuck, he'd ruined everything.
"Seriously Deku, what's wrong?" Ochako asked, leaning back into his space. "You're sweating."
If Izuku hadn't been hyperfocused on Katsuki, he would have completely missed the quiet growl. Izuku leaned out of Ochako's space immediately. Then paused. Was...that a possessive thing? A territorial growl?
His stomach flipped, but he tried to beat back the hopeful flutter. He'd promised Kacchan that he'd give him time to figure it out, right? He had to stay calm, be patient, and wait for Kacchan to make his move.
But it was hard to stay calm when Kacchan was stalking closer to him with murder in his eyes. Talk about mixed messages. He probably hadn't decided what to do but was leaning toward evisceration or level-ten detonation. That sounded likely, especially since Kacchan hadn't shown any interest in him before.
He just had to fall for the murder omega, didn't he?
"I'm fine, Ochako," he assured her, just as Katsuki had reached their desks.
"Get the fuck away from me, Floaty, you smell like someone threw up cotton candy," he snapped at her, snarling when she didn't move.
Iida sighed tiredly, as though he were an exhausted father who did not want to have this conversation again. "You shouldn't speak to your classmates like th—"
The growl that ripped out of the omega's throat this time was loud enough for the entire classroom to hear—loud and warning. Feral. "Get the fuck away from me," he snarled, pupils dilated and fangs bared.
It was wrong to be turned on right now, right?
"Back off guys," Izuku insisted, not taking his eyes off of Katsuki. Those beautiful crimson eyes snapped to him, narrowing. "Class is about to start anyway, just give him his space."
Kacchan's jaw clenched but before Izuku could say anything else, he'd thrown himself into his seat. There was a tremor to his shoulders, and Izuku opened his mouth to say something but was unfortunately cut off by Aizawa crawling out from under his desk as the bell rang.
The class was tense. Having an omega bordering on feral in the room was distressing and the alphas (and betas) in the room were chomping at the bit to comfort him. That, in turn, put Izuku on edge, and he had to restrain himself from snarling at Kacchan's friends when they came to check on him during breaks.
It helped that Kacchan snarled at them instead, refusing to be coddled.
It did not help that Kacchan was virtually ignoring him, aside from tensing if he got too close or spoke too much. Honestly, it made him feel...rejected. Which was fine! He'd survive. But he'd like a straight answer. He'd like to know for sure.
He'd also like to scent Kacchan all over so that Shoto would stop looking at him like that. The other alpha was completely transfixed on his omega ('Not mine,' he reminded himself), and even though Izuku had no claim over the fiery blonde, he wanted to gouge Shoto's eyes out.
The bell rang for lunch, and what came next happened very quickly. Katsuki launched himself from his seat, grabbed the front of Izuku's shirt, and started dragging him out of the room. "We need to fuckin' talk, fuckface."
"Kacchan?"
"Shut the fuck up and follow me," he demanded. Izuku fell silent and nodded, falling into step so that he was being guided instead of pulled.
"Wait, where are you guys going?" Eijirou called after them.
"You can't just drag him away like that!" Ochako cried.
"We'll be back later!"
"Mind your own fucking business, shitheads!"
If Izuku had a tail, it would be firmly between his legs. Kacchan was dragging him to the rooftop, only slowing down when he stumbled on a stair as they made their ascent. "Kacchan is everything—"
"Shut. Up."
One flight left. Hey, at least if Kacchan rejected him, he could give himself a concussion by rolling himself down the stairs. Convenient!
Katsuki pulled him onto the rooftop and slammed the door behind them before dropping his shirt. Then he jammed his hand into his pocket.
A second later, Izuku was pinned to the door—Kacchan's explosive palm in the center of his chest. On instinct alone, Izuku covered it with his own—intending to rip it off before he could detonate.
But then, he felt a scrap of paper under Kacchan's fingers, and he looked down. His heart stopped.
There was a coupon pressed against his chest. Izuku's stomach was free-falling. He looked up at Kacchan, only to find his eyes downcast and hidden. The tips of his ears were brick red, though. Gently, Izuku pulled the coupon from under Kacchan's hand, nearly whimpering when his hand curled back into his shirt once the flimsy paper was gone.
He looked away from Kacchan to read the coupon.
I accept your courting gift.
I accept your courting gift.
I accept your courting gift.
He sobbed, and Kacchan's head snapped up to look at him. "The fuck are you crying for?" he demanded, crowding in closer. Izuku sobbed harder. He couldn't help it, he'd always been a crybaby, and Kacchan had accepted his courting gift.
"I thought you were gonna reject me," he hiccuped, bringing his hand back up to hold the hand that was still gripping his shirt—stroking the back of Katsuki’s hand with his thumb.
There was no way Kacchan couldn't feel how hard his heart was beating.
"You're fucking stupid, then," he grumbled. "Most of the fucking idiots who tried to court me bought me shit I hated and were only thinking with their dicks."
"You liked my gift?" Izuku breathed, gripping Kacchan's hand a little tighter. He couldn't believe this was real. He was shaking—only grounded by his omega's proximity. Holy shit. Kacchan was letting him court him.
This might be the best day of his life. Or at least, it was tied with the day he met All Might.
"Fuck you. I will throw you off this roof."
"Can I kiss you before you do?"
"Not without a fucking coupon, shithead," Kacchan snapped, blushing furiously. Izuku grinned, still leaking from the eyes but so happy. He liked the coupons. He actually liked the coupons. "You can scent me, though," he amended quietly, casting his eyes back to the ground.
Izuku's wrist was planted over Katsuki’s scent gland half a second later. He whined when he stepped even closer—almost close enough to bury his face in Izuku's shoulder. "You can scent me too if you want," he offered quietly, trying not to sound too excited. He didn't want to pressure him, but he nearly collapsed from delight when Katsuki's hand wrapped around his other wrist and rubbed circles into his scent gland with his thumb—coaxing his scent out before pressing their wrists together.
Then, just when he thought it couldn't possibly get any better, Kacchan started purring—nuzzling Izuku's collarbone over his uniform and rubbing his cheek over his lapel like a contented cat. Izuku's heart squeezed and his breath caught—for a long moment, he was sure that he was going to die.
Then, Katsuki stepped back.
"Now go eat your fucking lunch, alpha." Izuku's blood burned. "If you bitch out in training, I'm rejecting your claim."
