Kiyoomi had always known there was something weird with Atsumu.
But he hadn’t really expected to find out he was a werewolf three months after they started dating.
When Miya Atsumu turned out to be a werewolf, Kiyoomi didn’t really know what to do with that.
Was he supposed to buy him a ball?
To pet him behind his ears and tell him he’s a good boy?
To let that goddamn gigantic wolf to sleep with him on his bed and lick his face like it wasn’t the most fucking antihienic thing in the world?
No, Kiyoomi Kiyomi didn’t fucking know what to do with a werewolf as his boyfriend, and it was driving him crazy how surreal the whole situation was.
The night Atsumu had appeared on his apartment and told him "Omi, I really, really need to tell you something, but you have to promise you're not going to freak out" and then began to just strip out in the middle of the living room, Kiyoomi had thought there were two options. Or Atsumu had done something really stupid and got a horrible weird tattoo while he was drunk, or he was going crazy.
"I didn't want to hide this from you for so long, but it wasn't really something you can say out loud to the first person I ever meet," Atsumu had said, standing awkwardly near the couch and wearing nothing but his boxers. "But, after all this time we've been together I think you deserve to know, and, well, decide if you still want me by yourself"
And honestly, Kiyoomi didn't knew what the fuck was going on until Atsumu's bones began to move beneath his skin and hair suddenly grow all around his boyfriend's body, until nothing remained from the man he knew as his boyfriend aside from his deep brown eyes.
"Dammit, Miya," Kiyoomi had muttered. "You know pets aren't allowed in the building, don't you?"
Wolf Atsumu just snorted at Kiyoomi before letting himself fall over the couch.
They got some rules after that.
Yeah, wolf Miya could shift inside their loft once in a while, but only if he promised to take turns in the cleaning.
No, wolf Miya wasn't allowed to sprawl all over the couch, because that shit of furniture was expensive, he couldn't just smear it with his damm wolf stinky furr.
Same thing with the bed.
A year later, Kiyoomi liked to think he’d finally gotten used to it.
But, well, you never really get completely used to something like that.
“Atsumu, stop it,” Kiyoomi demanded, exasperatingly closing both his eyes and trying to push his boyfriend away from him.
“But, Omi… You smell so good, ” Atsumu answered as he buried his face down the sheets and into his chest and took a deep, deep breath.
"I bet I smell like shit, I haven't even showered yet."
"And that's just why it's better," Atsumu said, smiling and turning to look at him. "You smell like sweat, and coffee, and…“ he continued with his babbling. And Kiyoomi found it disgustingly sweet, but also embarrassing. “You also smell like me, I love it when you smell like me.”
“Tsumu,” Kiyoomi complained as his boyfriend started licking and nibbling his way up from his chest to his jaw and neck, his hot breath making his oversensitive skin tickle.
“Omii—,“ he replied, not giving any signs he would be stopping anytime soon.
It was still far too early in the morning, Kiyoomi thought.
Damn stupid and stubborn werewolves, always wanting everything to smell like them.
He let Atsumu do as he pleased, anyways.
He didn't really hate it that much.
