Su Wanqing supported the poor young man Gu Mingyuan to marry into her family for twenty years out of love, firmly believing in the DINK (double income, no kids) promise. At forty, she accidentally became pregnant but was tricked into getting a tubal ligation; in reality, Gu Mingyuan had long ago fathered an illegitimate son, Gu Heng, with Wen Shuyun, and plotted to let the illegitimate son inherit the Su family's property. After discovering the truth, Su Wanqing secretly gathered evidence of bigamy, embezzlement of company funds, and credit card theft with the help of lawyer Yan Zhentao, and publicly exposed all of Gu Mingyuan's crimes at the group press conference. In the end, Gu Mingyuan was convicted and sentenced for multiple crimes, while Su Wanqing recovered her property, took her career to new heights, and transformed from a deceived wife into an independent and clear-headed helm.
