Urban white-collar worker Shen Qing marries Hong Yu. At the wedding, she receives an empty red envelope from her mother-in-law He Yulan meant for the formal name-change gift, but she endures it with grace. The mother-in-law favors Hong Yu's ex-girlfriend Sun Meiqin, and Shen Qing catches her buying luxury bags for Sun Meiqin, but Hong Yu firmly steps in to protect his wife. Shen Qing accidentally overhears her mother-in-law plotting against her, yet at a family gathering she wins the relatives' approval with her thoughtful handling of everything. When her mother-in-law breaks a bone in a car accident, Shen Qing cares for her attentively, easing their conflict, and Hong Yu also confesses the truth that Sun Meiqin cheated, leading mother-in-law and daughter-in-law to reconcile. Later, Shen Qing and Hong Yu compete for projects on behalf of their respective companies, and the mother-in-law, mistakenly thinking her son is having an affair, storms into the company—only to learn it was a project assistant, leaving her deeply guilty. She then brings out her private savings to support the couple.
