Yoon Seo-woo, the illegitimate daughter of Congressman Yoon Jae-jun, was raised to be quiet, submissive, and obedient. Living in a wealthy household after growing up in a wild orphanage, she suppresses her true nature—a secret, kinky fascination with savage-like men. Her father arranges a marriage for her with Kim Eon-hyeok, a tall, muscular, and incredibly handsome executive at WM Construction.

Eon-hyeok is a control freak who never lets anyone close, treating Seo-woo merely as a beautiful, obedient doll designed for his pleasure. He expects a marriage consisting only of base, animalistic intimacy. However, as the arrogant, self-assured man begins to break down, the dynamic shifts from cold control to an obsessive, possessive, and unexpectedly emotional entanglement.
