Su Wan, who died tragically in her previous life, returned and vowed to expose the conspiracy and regain her family property. She founded the fashion brand "Nishang" with her forward-thinking vision and emerged in the domestic and foreign fashion circles. However, she had a fierce conflict with the European textile giant Gu's because of the core fabric formula "Cardinal". In the game with Gu Yanchen, the heir to the Gu family, the relationship between the two went from confrontation and defensiveness to forced cooperation, and a secret love arose.
However, as rival Su Rou was framed and the internal struggle of the Gu family surfaced, Su Wan discovered that her life experience was closely related to the Gu family - she may be a descendant of the Gu family who was living abroad, and she was suspected of being related to Gu Yanchen. What is even more shocking is that her mother Lin Wan, who was supposed to have died of illness long ago, may still be alive and imprisoned by the mysterious man "M". During the investigation, Su Wan gradually uncovered a shocking conspiracy that spanned twenty years: the internal struggles of the Gu family, the shady story of transnational business, and the truth that her mother was forced to remain anonymous.
With Gu Yanchen's secret help, Su Wan finally brought down Gu Hongru, the mastermind behind it, but faced the ultimate test when "M" threatened the core key of the Gu family with his mother's life. In the end, she and Gu Yanchen teamed up to break the situation, rescued her mother who had been imprisoned for many years, and made the truth known to the world. After experiencing the test of life and death, Su Wan chose to put aside her hatred and take her parents away from the dispute, while her relationship with Gu Yanchen left an open ending in relief and expectation. The story combines business war, revenge, suspense and emotional entanglement, showing the heroine's growth in adversity and ultimately achieving self-salvation.
