After suffering an accidental miscarriage, Lin Wange calls her husband Jiang Fanyu for help, only for his close female friend Su Yao to answer while he is asking her for a towel. In her deepest despair, her former arranged-marriage partner Jiang Min, president of Gaoyuan Group, rescues her. He offers to be her close male friend to help her reclaim justice for the grievances suffered during her five-year marriage. Lin Wange then appears before Jiang Fanyu with Jiang Min, perfectly mirroring the boundary-crossing behaviors he had with Su Yao. While Jiang Fanyu gradually breaks down, he remains unaware of Jiang Min's genuine feelings, and her ultimate revenge has only just begun.
