b!Lee Seowoo x a!Moon Dohyun
Seowoo is working overtime one evening to cover for his omega manager only to be jumped by an omega in heat. Feeling horrible, he finds the omega and asks him out only to quickly fall in love with him. Dohyun, the "omega" from before, is actually an alpha who only bottoms so he conceals his dynamic to have a chance with Seowoo who knew the whole time he was an alpha.
