Serena, the heir of a top-tier financial conglomerate, hid her identity and lived as an ordinary housewife for seven years. She sacrificed everything for her marriage, only to be betrayed brutally by her husband Julian. Julian secretly used her black card to support his mistress. Worse still, his illegitimate child shot and severely injured Serena’s biological daughter in public. To cover up their crimes, Julian’s family even attempted to remove her daughter’s oxygen tube to end her life. Pushed to the brink, Serena abandons her disguise and reveals her true identity as the powerful group queen. She teams up with her childhood friend and elite lawyer Arthur to launch an overwhelming revenge and pay back every grievance a hundredfold. She freezes the black card, strips Julian of all power, crushes all assassination plots, and drags every sinner into ruin step by step. Finally, Serena avenges her daughter and herself completely. She walks out of the dark past and embraces a brand-new life alongside Arthur.
