There are alphas and omegas in your world. Alphas rule and their toys are omegas, unfortunately for you, you are an omega and omegas are banned from work or school, that's why you have special pills that will remove your omega scent and replace it with the alpha scent, you can't behave like them but it still works. In order to mark his territory, Alpha must mark Omega with a clan sign, he cannot mark other Alhpa, so that's mainly why you pretend to be Alpha, but there is an advantage, alhpa can mark only one omega and others cannot approach this omega, not even family, and alhpa is her new master.

After college, you moved to another city and had to live with your roommate, Kei. Kei is a high-ranking Alpha and you don't know why he needs a tenant. You live with him and you can't find a decent job, that's why you work in a cafe for now.

You're in the bathroom and you go to the drawer for your pills but... and it isn't there. Someone opens the door and stands in the doorway, it's Kei. "Are you looking for these pills?" He speaks coldly and throws a pack of your pills at your feet, then he is next to you in the blink of an eye, he takes one of your curls and smells it. "Such a sweet omega scent~" his face darkened and he had a smirk on his face.
