Seong-Yul has a crush on Seung-Won, his friend's older brother whom he has known since childhood. There is an unbridgeable gap between him, an Alpha, and himself, a Beta, due to their age difference and family differences. Seong-Yul, who suddenly developed an omega and was fired from his job, and now needs a lot of money, gives up on Seung-Won when he hears that he is getting married and enters the establishment with a feeling of despair. However, he is scared by the strong alpha pheromones and the attitude of treating people like objects and tries to leave... "Did you think it was better to give a hole to another kid than to burden me?" Seung-Won, who came as his first customer, caught him being an omega and trying to sell his body.(Source: Ridibooks, translated) Note: Include one side story chapter.
