Yu Wan transmigrated into a book, becoming the tragically fated, wicked child bride of the original male lead. The story began abruptly; when she arrived, the male lead's family had already been poisoned by the original owner, and she was holding a bowl of poisoned medicine, offering it to the male lead's lips. She heard herself say, "Husband, drink your medicine." What a ridiculous "elder brother, drink your medicine!" Yu Wan was weak, pitiful, and helpless.

Whatever you want, I'll give you, including my life." Yu Wan: "..." Damn it! The plot has gone awry! The aloof male lead has gone mad...
