In a modern bustling city, top wealthy families are fighting openly and secretly. The Su family's business went bankrupt and they urgently needed help from the Li family. The stepsister Su Yurou, who was scheduled to get married, was afraid of the rumors that Li Yanchen was "killing his wife", so she planned with her stepmother to force the heroine Su Wan to marry her instead. Su Wan, on the other hand, lived alone with his five-year-old son. In order to give his son a stable life, he reluctantly agreed to a marriage and signed a contract marriage with Li Yanchen. Then he entered a wealthy family and started a counterattack and a slap in the face.
