After six years of marriage, Cheng Wanqing has silently repaid 600,000 yuan in startup debts for her husband, Xu Jiashu. On their wedding anniversary, she discovers that she has won the 10-million-yuan jackpot and plans to help her husband through his financial troubles. However, Xu Jiashu mistakes a lottery ticket with similar final digits for his own winning ticket and immediately presents her with a divorce agreement, insisting that the prize money belong to him alone. Despite Cheng Wanqing repeatedly urging him to check the ticket number, he refuses to listen. Instead, he schemes to claim sole ownership of her original designs while making her share his debts. After their divorce is finalized, Xu Jiashu goes to collect the prize, only to discover that he has won nothing. After a series of disputes, Cheng Wanqing successfully protects her creative work and property, establishes her own independent design studio, and begins a new chapter in her career.
