On the eve of her return to China, Chu Sang learns the devastating news that her close friend Yu Sui has fallen from a building and passed away. In their youth, the two depended on each other, and Chu Sang once promised to keep her safe. However, after Chu Sang went abroad, Yu Sui was taken back into the Su family by her biological father, Su Yunnian, repeatedly lying that she was doing well while enduring torment alone. Yu Sui caught her fiancé, Zhou Ze, and Su Nian in an illicit affair, and unfortunately fell from the building during their confrontation. A grieving Chu Sang resolves to enter the game herself, pretending to be meek as she enters the Su Group, vowing to make all the perpetrators destroy each other and pay the price.
