Lin Mo, a genius cosmetics developer, signed a one-year marriage contract with Gu Yanchen, the president who needed a "shielding" wife to stabilize the family business in order to escape the difficulties of his original family. The two went from cooperating like "best friends" to test each other and compete with each other, to jointly deal with the open and secret attacks in the workplace and the numerous conspiracies within the family. In the process of elegantly "slapping" the hypocritical villain and tearing up green tea with his hands, the sinister CEO who is accustomed to pretending is deeply attracted by the heroine's independence and tenacity, and quietly becomes sincere. The contract is about to expire, and when all the conspiracy is revealed, the two must face their own hearts and stage an urban high-IQ offensive and defensive love from "fake play" to "real thing".
