Synopsis：For four years, Shiyue has kept up the meek façade of a wealthy housewife while secretly gathering evidence of her husband’s infidelity, waiting for a chance to break free. After catching him cheating, she plans to strike back with a revenge date, but instead runs into his close friend Qin Zhao, a notorious playboy in their social circle. Qin Zhao is drawn to the ruthlessness beneath her proper exterior and proposes that they form a mutually beneficial, ambiguous arrangement—becoming each other’s partners in revenge, distant in public but entangled in private. Qin Zhao helps her maneuver through the divorce battle, while Shiyue gradually develops feelings through her growing reliance on him. When her husband’s schemes are crushed and the shackles of marriage are finally removed, the two allies are forced to face their true feelings. Can this relationship, born of calculation, settle into a genuine life together?
