Ji Wu transmigrated into a book, entrusted by the system to redeem the villain Tan Xu, but was forced to leave after falling in love with him. To make him let go, she asked Xu Qian to play out a change-of-heart act. Three years later, the system malfunctioned, and she returned to the book, collapsing at Tan Xu's doorstep on a rainy night. Her once down-and-out former lover has now become a rising elite in the business world, convinced that she is a gold-digger who despises poverty and loves wealth, and marries her under the guise of revenge. After marriage, though his words are full of hate, he always reaches out when she is vulnerable; she wants to explain, but fears using her hidden hardships to win forgiveness. Until he discovers the medicine she hid, can the three-year misunderstanding be unraveled?
