If Yamada was not an omega Tōkan would know exactly what to say to that, but it's crossing a line, here. He assumes a stance.

Tōkan grabs it and looks at it. "Didn't use it, huh?"

...but then there's the pheromones, and he immediately stretches his arm out to hold the cloth bag as far away from him as possible. "What the hell? Did you rub yourself all over this or something? Your pheromones are everywhere!"

"Fuck you," he says with a swing directly at Tōkan's face.

He dodges, still a little bit on the back foot, and dodges and dodges and dodges until he slips on a soda can and falls onto his back. He immediately rolls out of the way of a kick and leaps up to a crouching position.

"I'm gonna kill," swing swing swing, "every shitty alpha," swing, "but especially you."

Dodge dodge dodge. "Especially me? The fuck did I even do?"

"Not my friends," he says, parrying a blow and returning it with one of his own, finally. "And were you just not listening? I don't look down on omegas and I don't think anything of the sort about you. My mom's an omega."

"Urghhhhhh." He's doubled over and trying not to heave, but most importantly he extremely does not need an omega crushing on him. Does not need that at all.

(And when he gets home, goddamnit, he's the one being a creep and getting off to someone's scent in a cloth bag. In his defence Inori's pheromones smell incredibly hot. Perhaps not so much in his defence, he keeps thinking about fucking the omega.)

(Maybe Subaru was onto something when he said this is addictive.)

Inori is waiting for him at the school gates the next morning. "We weren't finished."

"—you're the one who ran away," he replies on automatic because fuck he had actually hoped Yamada would just give up after that.

"You kept saying weird shit. Stop doing that and come die like an alpha."

"I have class. And so do you."

"You're asking me to skip class so that you can kill me."

"Yep."

"Fuck off." And through the gates but he's got a suspicion he's just not brushing Yamada off that easily.
