Her fiancé fell to his death, leaving Su Wan with a huge debt and a fatal mystery. The powerful Lu Tingyuan came with a marriage contract: "Marry me, and I will help you find out the truth." She thought it was redemption, but in fact she stepped into a prison of revenge - he hated her "father" for betraying him, and wanted to trap her by his side to take revenge day and night. After the marriage, there was a secret confrontation. She pretended to be depressed and secretly collected evidence of his crime, but unexpectedly uncovered three truths: he was the mastermind of the conspiracy, her biological father was the real murderer of her husband, and she was actually the legacy of his family. Faced with the choice between law and emotion, she submitted evidence and both of them were imprisoned. A few years later, when they met again in Heavy Rain, he tore up the divorce agreement and begged for reconciliation in a mute voice: "If the grudges are evened out, can we start over?" This dangerous love that began with revenge will eventually be resolved in redemption.
