No Spicy Romance Allowed!
Makoto is as average and ordinary as an omega gets. He's nothing like Rio, the model du jour he's been assigned to manage. Rio is charismatic, popular, drop-dead gorgeous, and most importantly, an alpha—everything Makoto can't stand! Makoto is determined to keep their relationship strictly business, even though Rio seems fixated on winning over his prickly new manager with sweet talk and claims of love at first sight.
Drastic Omega

It doesn't matter who his client is, he'll sleep with any Omega, Beta or Alpha as long as he's the one on top. Turning his pleasures into money Aoi enjoys his life until one day when an Alpha who wasn't swayed by any Omega server at the club catches his eyes. The man, who emits a pheromone he's never felt before, relentlessly seeks Aoi out.
