In order to save her seriously ill mother, Su Tang, an ordinary girl, signed a contract and became the "agreed wife" of wealthy heir Lu Tingxuan. He is cold and distant, suffers from an emotional disorder, and views marriage as a therapeutic experiment; she is warm and tough, and just wants to survive a year and get paid. I never thought that the daily lights and the smell of rice would melt my frozen heart. When the contract expires, sincerity has already quietly grown. This is a marriage that started as a transaction, but it taught two lonely people how to love.
