The medical girl Su Nianqing once saved Gu Ziheng's life, and the two made an engagement, loving each other. Since his cousin Shen Wanning returned from exile, Gu Ziheng's preference has been completely tilted. Su Nianqing was framed many times and was sent to a brothel to humiliate her for three months. After returning, Fang Yuan changed owners, her parents' belongings were destroyed, and her beloved cat died tragically. She lived as lowly as dust in the Gu Mansion. When Shen Wanning used blood as medicine to seduce each other, Su Nianqing hid her edge and used blood to poison her, redeeming her old friend's daughter, and worked hard every step of the way. The deep love in the past has become a sharp sword. This time, what she wants is not to look back, but to make the unfaithful person pay the price.
