At her engagement banquet, Ruan Tingxi was publicly abandoned by Xie Yansong, her boyfriend of five years, suffering utter humiliation. In her despair, she met the mysterious mother-in-law Li Yajun on the rooftop, who proposed that she flash-marry Liu Yubai, her secret crush of seven years. Ruan Tingxi impulsively registered their marriage, thinking she was marrying into an ordinary family, only to find that both her mother-in-law and husband were hidden tycoons. Unreconciled, the Xie family mother and son successively spread rumors, smashed her house, plagiarized her designs, and launched commercial suppression. With the joint assistance of her mother-in-law and husband, Ruan Tingxi grew, stabilized her career, gathered evidence to fight back, and finally exposed the Xie family's conspiracy. The scumbag ended up in debt, while Ruan Tingxi reaped a double harvest of career and love, welcoming a fulfilling life.
