Su Wanning, a prosecutor in Lanjing, Thailand, returned to the Zheng family home in Lopburi with her boyfriend Zheng Chengye to meet his parents, and witnessed her prospective mother-in-law Lin Qiuhe enduring long-term mistreatment from her family. Standing up for justice, Su Wanning produced her prosecutor's badge to deter the unreasonable relatives and urged Zheng Chengye to face the problem. Zheng Chengye chose to register their marriage and set up a home with Su Wanning, moving away from the Zheng family. Gathering her courage, Lin Qiuhe left the repressive household, attended cooking classes, and realized her self-worth. Zheng Daqiang regretted and begged for reconciliation, but was firmly rejected by Lin Qiuhe.
