Her family destroyed and her younger brother critically ill, Su Wan, once the cherished heiress of the Su family, is now a helpless orphan at everyone else's mercy. Her stepmother forces her to sign away her inheritance, while her stepsister treats her as a stepping stone. Just as all hope seems lost, Li Jinhan, CEO of the Li Group, arrives with a contract and an imposing offer: “Marry me and be Mrs. Li for three years. I'll save your brother's life and take on the Su family's debts.”
