Lin Yuan, a common citizen, married into the wealthy Su family and became a "waste son-in-law" in the eyes of everyone. Facing the internal power struggle of the Su family, external business crises and challenges to personal dignity, Lin Yuan used humor, self-deprecation and wit to break through the difficulties step by step. With the support of his wife Su Jinyao and Ye Hong's help, he grew from a marginal member of the family to a key figure in the Su family. Each of the three volumes of stories has its own theme, covering Lin Yuan's early marriage, family struggles and external counterattacks, and the final clarification of his own identity. The story has ups and downs, a tight rhythm, and coexistence of emotion and comedy until the perfect ending.
