Burdened with a seemingly insurmountable debt incurred by his absentee father, Kim Euihyun knows that for an omega—a secondary sex capable of bearing children—like him, only a painful fate awaits. Clinging to his younger brother, Euiyoung, whom he has been responsible for since his birth, Euihyun walks into the ocean to drown together and escape their wretched life. However, one of his creditors, the imposing Yeo Taeju, interrupts him, leaving Euihyun certain that a future of misery is set in stone. Taeju, who is blessed with the superior characteristics of an alpha, finds Euihyun's pheromones captivating and wants to keep the omega under his thumb. Offering Euihyun more options than he typically would give a debtor, Taeju hopes Euihyun will live to serve him and him alone. Though Euihyun does not trust the gangster, he has little choice but to cooperate if he wishes to provide Euiyoung with a better life. [Written by MAL Rewrite]
