The Su family went bankrupt, and Su Qingyuan was forced to pay off her debts with marriage. She married Lu Tingyuan, who had a grudge against the Su family, and fell into a love-hate purgatory. Lu Tingyuan was angry with her because of his mother's death. He used indifference and humiliation as a blade and imprisonment and torture as a cage to crush her dignity. The surprise of pregnancy turned into a deeper humiliation. The forged paternity test and the torture of being forced to a hospital left her struggling in despair. After escaping, she raised her son who suffered from heart disease alone. She lay dormant for three years and transformed into a strong person in the workplace. However, she became entangled with Lu Tingyuan again due to a business conflict. The exposure of the parent-child relationship broke the deadlock, and Lu Tingyuan regretted it, but the pain of the past has long been engraved in his bones. When the truth about the unjust case comes to light, mixed with family intrigues, business struggles and parenting difficulties, can this belated redemption melt away the frozen scars? The fire is not extinguished, the cage is hard to break, and in the abyss of sadomasochism, love and hate finally become a long tug and redemption.
