Shen Jingzhi is forced to take the place of a missing noble family's beloved daughter and marry into the powerful Prince Regent's household, where she becomes a stand-in wife and endures endless contempt and schemes. Driven to desperation, she binds herself to a “Role-Playing System” and draws scripts for different identities, including a cool, aloof divine physician, a bewitching femme fatale, and an iron-blooded escort agency chief. Seamlessly switching personas in the household, the business world, and the royal court, she uses her acting to break through deadlocks and her schemes to turn the tables. Xiao Jingheng initially regards her with cool scrutiny, using and testing her, but gradually becomes captivated by her many-sided, vivid soul, caught in a maddening tug-of-war over the question: “Just how many faces does she have?” As their secret identities are exposed one after another and factions reshuffle amid the bloody struggle for the throne, the two join forces to overcome every crisis, bring down the mastermind behind the conspiracy against her family, and break the curse of the stand-in.
