Zhou Yan, the chairman of Yuanchuan Group, concealed his identity and acted as a seemingly low-status son-in-law in the Lin family for three years to fulfill the entrustment of a deceased friend. When his father fell seriously ill and urgently needed money, he tried to take back thirty thousand lent out, but was met with all sorts of evasions and hardships from the Lin family, while his wife Lin Wanqing blindly demanded that he consider the overall situation of the family. With a cold heart, Zhou Yan chose to divorce and return to his identity, exposing the heavy shady backstories of internal embezzlement of public funds, material falsification, and evidence forgery within the Lin family in his capacity as an auditor. As the storm settled, the parasites of the Lin family accepted legal sanctions, Zhou Yan safeguarded the rights and interests of ordinary employees, the old debts were settled, and a brand-new chapter began.
