When he's in rut, Hitoshi goes mute.
Omegas bite their heat partner because it's common for them. Alphas don't have the same tradition because the claim won't stick unless the partner bites first.
The villain is in the cop car, he's written out his note explaining that he was hit with this stupid sex pollen and needs to have his emergency rut list called for the nearest hospital.
"Nighthide!"
Hitoshi freezes.
He was in the middle of his escape from the cops who were relaying the information he'd given.
But that's Katsuki fucking Bakugou's voice.
The only omega that his Alpha wants during his ruts.
He doesn't have the same urges as most Alphas during rut. He'll take cuddles and scenting over sex any day. Which is exactly why he never calls Katsuki when he's in rut.
Their other omega pack-mates come over to his den and cuddle him, but not Katsuki.
"You went mute already?" Katsuki's voice is softer as he lands on the sidewalk, in full hero gear.
Hitoshi nods stiffly, eyes darting to the side as his Alpha starts talking about scenting his mate.
He's put on a custom-made muzzle from Mei that he wears throughout his ruts because his Alpha has spoken out a couple of times and used his quirk with an alpha command.
"Okay, they called me, so I'm taking you to my agency. It's just down the road, will you be okay until we get there?" asks Katsuki gently as he walks up to him, voice getting quieter as he gets closer. "I have heat/rut rooms set up there."
Hitoshi just nods before signing, "Muzzle stays on, but rut room at agency is fine. Tell Zawa to send our file so you know everything."
"He's already sending it," replies Katsuki with a half-smirk. "He was my second call to confirm that the hospital wasn't fucking up."
Hitoshi's snort comes out silent, but it's there. Katsuki seems to have noticed because his smirk curves into a soft grin.
"You wanna tell me why I was even on the list though? You never call me for rut cuddles, or shit like it, ever. So, this was a surprise," Katsuki seems genuinely curious as he twists and motions for Hitoshi to walk with him.
Hitoshi's fingers start responding before his mind can stop them from spilling everything.
"I'm in love with you, and my alpha sees only you as a mate."
"Well, shit, Alpha, why didn't you tell me before?" Katsuki's question sounds rhetorical. "Actually, I don't care. I'm in love with you too."
Hitoshi's brain stalls as they get closer to Katsuki's agency, his rut and his inhibitions at a standstill trying to process that not only has he just been confessed to, but the omega he wants to mate has called him Alpha.
He's definitely keeping the muzzle on because he can't mate this man before he courts him, but at least now, his gifts can see the light of day.
