To secure a marriage to the heir of the powerful Kunhyang Group, Cha Jung Won orchestrates an elaborate deception, assuming the identity of a friend to infiltrate his family. But her carefully constructed world unravels when she meets Han Hye Ra – the woman destined to be her mother-in-law, and shockingly, her own biological mother. Years ago, Hye Ra abandoned Jung Won to escape a life of hardship and climb the social ladder, leaving behind a legacy of pain and unanswered questions. Haunted by a father wrongly accused of murder and a mother who vanished, Jung Won is poised for a wedding when a devastating truth surfaces: Hye Ra is her birth mother. Suddenly, revenge becomes her driving force. A brutal battle of wills ignites between these two women, fueled by layers of deceit and betrayal. In a world built on fragile lies, only the bonds of blood remain undeniable—but will that truth ultimately shatter the web of falsehoods, or be consumed by another layer of deception?
