Pei Yu, the CEO of the Pei Group, is engaged to Jiang Yueyue, the heiress of the Jiang family. At the same time, he maintains a secret relationship with the fearless biker beauty Yu Wanning. Eventually, he ends their affair, claiming he has to get married, and offers her a breakup settlement worth ten million.
What he doesn't know is that Yu Wanning is the rightful heiress of the Yu family, whose fortune was stolen by the Jiangs and whose mother was persecuted by them. She approached Pei Yu from the very beginning only to seek revenge.
When the Jiang family summons Yu Wanning back, the painful memories of the abuse she once suffered only strengthen her determination to take revenge. Taking advantage of Pei Yu's younger brother, Pei Yanchi's growing affection for her, she draws closer to the Pei family. After reuniting with Pei Yu, the two become entangled in an increasingly complicated relationship.
As the Jiang family repeatedly tries to suppress Yu Wanning, she joins forces with Pei Yanchi to fight back, exposing the family's scandals and dark secrets one by one.
Although Pei Yu continues to honor his engagement to Jiang Yueyue for the sake of securing an important commercial formula, he finds himself becoming increasingly possessive of Yu Wanning. He finally realizes that he has fallen in love with her, breaking the one rule he had always lived by—never letting emotions get involved.
In the end, Pei Yu chooses to stand by Yu Wanning's side and helps her carry out her long-awaited revenge.
