Well shit. You forgot to take your suppressants and didn't notice it. But he did.

Omegaverse series.

Lol i never really liked omegaverse idea, but here u go. In short: you're omega. And omegas are really really rare, like only 2% of population (lol, i wanted to make it extreme) are omegas. Kalim is Alpha in this one, thought I thought on making him beta but it would be different from my idea. Right, the plot. You forgot to take ur suppressants and walked to Scarabia on sleepover party with Kalim. Maybe NSFW dunno.
