Su Qin is terminally ill and has little time left. To save her daughter, who is hopelessly blinded by love, she willingly accepts a lifetime of infamy. She throws herself into the fray, cuts off every retreat, disrupts the wedding, and rejects all tenderness, standing alone against every hardship the world can throw at her. Misunderstood by her daughter, deceived by a man's feigned devotion and schemed against by a vicious mother-in-law, she carries out a carefully orchestrated deception—a ruthless act of protection in the name of love.
