The protagonist, a defective Omega with an extremely low chance of conceiving, is told by the doctor that only a top-grade Alpha can get him pregnant. Desperate to have a child, he finds Roderick—the S-class top-grade Alpha heir of the Dunlap family—passed out drunk, takes him home, and ties him up to force conception. Initially, Roderick resists fiercely, but he gradually falls in love during their time together. After the protagonist successfully gets pregnant and plans to set Roderick free, Roderick locks him up instead. Pulled between their status gap and inner barriers, Roderick firmly chooses the protagonist, even teaming up with his family to stage a "scheme of suffering" to touch him. In the end, the protagonist lets go of his past trauma, accepts Roderick’s love, and they decide to get married and stay together.
