After being forced to marry cold CEO Dominic as a substitute for her sister Serena, Chloe endures a year of neglect. When Serena returns claiming to be Dominic’s long-lost love, Chloe decides to leave. At a charity gala, she publicly divorces him. Dominic, revealed as a mafia boss, abducts her to his estate, where she discovers his obsessive shrine of secretly taken photos. He confesses he always loved her and that he legally exposed her family’s money laundering. Instead of escaping, Chloe awakens as a cunning “villainess,” manipulates Dominic’s possessiveness, destroys Serena, and survives an assassination attempt by her sister and father. Using her micro-expression skills and criminal psychology, she helps Dominic kill the attackers. She exiles Serena and her father to a South American mining zone. Finally, Dominic marks her with his name and makes her mafia queen, completing her transformation from substitute bride to powerful matriarch.
