Chapter Text
Izuku slammed his hands against Katsuki’s chest, creating distance between them. “Do you wanna fuck me or do you wanna fight me?”
Katsuki was paralyzed at the question; Deku had never been that straightforward, never looked at him this furiously. “What if I say both?” he returned a little dazed, a little breathlessly aroused.
“Then pick which one is more important to you, Kacchan. I-I can’t keep doing this!”
Did he read this wrong? “What the fuck are you talking about, Deku?”
Izuku scoffed and paced around, moving his hands haphazardly as he spoke. “You-You’ve known how I’ve felt about you for the past three years and you’ve never made a move. You challenge and insult me most days, we are kind of friendly other days, but you only ever express any interest when you’re getting close to your rut.”
Then, the omega paused and looked at Katsuki with such a raw expression, eyes already shining with tears, that it made his heart clench. Why was the nerd affecting him like this?
With a pained look of resignation, Izuku pried his eyes away from the blond’s, refusing to meet his gaze any longer. Taking a deep breath, he continued. “My heats are getting worse without an actual mate, Kacchan, and I refuse to share them with you if you won’t take me seriously. The next one’s in three weeks,” he trailed off.
“Deku, what’re you-“ the freckled man raised his hand, letting him know he wasn’t done.
Why was Deku saying this? Katsuki knew the nerd’s heats just like he knew his own ruts. He didn’t want a mate, but something about letting Izuku spend his most vulnerable moment with anyone else ate at him, so they’d become heat and rut partners. He knew of the nerd’s feelings, but he never thought he’d need to act on them; they were already living together, what else did they need?
Tears were flowing freely now, but the greenette pushed through between sobs.
“The next one’s in three weeks, and both Kirishima and Shinsou have offered to bond with me and help me through them.”
Katsuki growled, “What the hell?!” How dare those two fuckers offer that to his omega.
But Izuku didn’t cower, and he didn’t take anything back—he turned around and growled back in challenge, eyes already puffy and red from crying. “You don’t get to be jealous or have any claim over me, Kacchan!” He huffed and turned away as if struggling on whether to stay or go. “I-I love you, but I can’t wait anymore. If nothing changes, I’m accepting one of their offers. I’m sorry for being such a burden over the years.”
'You aren't. Stay.'
The blond grabbed him by the wrist. “Stop this shit. Like hell you will! Shitty Hair is my best friend; he’s with Raccoon Eyes anyway! And you can’t seriously be considering Mind Fuck over me, right?” He was breathing heavily now, his voice desperate.
Who did this bastard think he was?
'Stay'
“Not that you’d care, but Mina welcomed me into their pack; she was the one who suggested the offer after going with me to my last checkup, something you’ve never really bothered with."
'Shit'
"They’re both alphas, they wanted an omega they could trust, and she saw the opportunity when she noticed how bad my situation was. And Shinsou, no, Hitoshi, has become a close friend over the years. If you didn’t have your head so far up your ass, you’d know that.”
Katsuki was frozen on the spot, trying to process everything that had been said.
"I love you, but I don't want to feel like this anymore."
The blond did not, could not, respond. He saw the look of disappointment and sadness on Deku’s face, smelled the distress and anger in the air, felt warm tears streaming down his own face, felt Deku’s lips on his skin as he gave him one last kiss good-bye, tasted that wonderful spiced-apple scent he’d come to crave, and heard the heart shattering wails that he no longer knew whether they were the omega’s or his own.
He blacked out at some point.
When he opened his eyes once more, his Deku was gone, little to nothing was left in the omega’s room except for a note, and his house felt foreign; it no longer felt like home.
Taking the note, the blond curled up in the omega’s bed, taking in as much of his scent as he could. It was grounding. He could feel that darkness that threatened to consume him recede, if only for a few minutes, until the scent faded. His alpha seemed stuck in a constant, manic state of
We hurt our omega. Omega left us. Get omega back!
How could Izuku leave like that? They’d always been together; Deku always followed him. This had to be some sick joke; his childhood friend would never abandon him like that, would he? He clutched at the paper, unwilling to open it just yet.
'It hurts, it hurts, it hurts.'
Even in their worst times, the omega had always had a smile on his face, as wobbly as it might have been. Even when they fought back at ground beta, he had taken it as a challenge; he’d seen the moment for what it was, and he’d never put the blame on Katsuki or left. Even when Katsuki had left him, Izuku had always come back, so surely Deku would be coming back to him—right?
We failed our omega. Omega hates us. Get him back!
His eyes welled with tears once more and he gulped down the sob that threatened to arise. It was so fucking stupid! Katsuki didn’t want a mate, he didn’t want to be tied down, he only needed an omega to keep his alpha in check, and they’d been together their whole lives, so he was the best alternative. Besides, why would he take Izuku’s feelings seriously? One day, the freckled man would realize that he didn’t forgive the blonde for all the pain he put him through, and then what?
Why did it feel like he was breaking? Like he was the guilty one when Deku had just ruined their mutually beneficial agreement. Except that…it hadn’t been mutually beneficial, had it? Not to Izuku.
With some effort, he sat on the bed and wiped furiously at his eyes. Katsuki Bakugou was no coward. Taking a deep breath, he slowly unfolded the now wrinkled paper Izuku had left. The nerd had most likely written himself up a speech he didn’t get to give, so he left it.
Inhale. Exhale
White knuckles punched the wall in frustration. He couldn’t do it!
Katsuki threw the note on the bed without looking at it and paced around the room.
This wasn’t pain or cowardice. Hell no! This was anger. Yeah, Katsuki was pissed. After all the work they’d put in, all those years of friendship, all the battles they’d fought together, and it was this easy for Izuku to forsake him?! Fuck him!
Fuck that nappy-ass Shinsou for making a move on him. And best friends, what best friends? Those assholes, Ei and Mina, pounced the moment he turned his back; didn’t even fucking consult him on it. After almost ten years of friendship, this is how he’s treated? Fuckin’ traitors, all of them.
If Deku wanted him to know something, he’d have to say it to his face, or not at all. He wasn't sure what the end game was, but he was not about to play the omega’s twisted little game.
Tossing the note on the dresser, he went to the bathroom, got dressed, and left for the agency. He didn’t want to be late; after all, he had patrol with Deku.
