The smart and tough psychiatrist Su Qingxu fell in love with the cheerful musician Lin Yao and quickly got married. After getting married, Su Qingxu was shocked to discover that the mother of her lover, whom she tried every possible means to please, was not only the "evil mother-in-law" who made things difficult for her, but also her immediate boss in her new job. Facing the double pressure of her mother-in-law in life and work, as well as the constant provocations of her love rival, Su Qingxu relied on her professional knowledge and high emotional intelligence to show off her tricks and gradually understand the fragility behind the strength of the "evil mother-in-law" and resolve the conflicts step by step. Not only did he protect his love and career, he eventually gained the approval of his mother-in-law, turning a frantic "mother-in-law and daughter-in-law relationship" into a real family. The highlight is that the male protagonist does not use golden fingers or forceful confrontation, but uses psychological knowledge and empathy to "outsmart" the mother-in-law, showing a high-EQ family relationship attack and defense.
