Shen Zhiyi, a successful CEO, and Gu Mingyuan built their business together. However, after listening to rumors, her mother-in-law mistakenly believes that her son married into the Shen family and that the grandchildren will take their mother's surname, leaving her resentful. Their greedy sister-in-law, Zhao Meiqin, secretly pockets the 20,000 yuan their elder brother and sister-in-law send every month for their mother's living expenses. She even tricks their mother into picking up garbage on livestream to gain sympathy and earn gifts. When Shen Zhiyi catches her in the act, she exposes her wrongdoing and firmly defends her humiliated mother-in-law during a shopping trip. She also presents her prenatal examination documents and promises that the baby will take the Gu family name, finally putting the older woman's worries to rest. When the couple return to their hometown to pay respects at the family graves, they donate tens of millions of yuan to renovate the ancestral hall. With conclusive evidence of Zhao Meiqin's embezzlement and malicious rumors, the police take her away. The younger son finally comes to his senses, and the relationship between mother-in-law and daughter-in-law is completely reconciled.
