Three-year-old Lin Wanwan's parents died, and she was pushed into a desperate situation by her money-grubbing cousin's family. She was chosen to be the princess to bury the sick and frail prince. After entering the palace, she seemed ignorant and cowardly, but she impressed the prince with her pure heart. In the deep palace, witchcraft and poisonous plots and disputes over the inheritance of the heir continued one after another. Concubine Rong, the second prince and others were pressing her step by step, seeing her as a pawn and a scourge. Wanwan was not stupid and told the prince everything she saw and heard. The two protected each other and uncovered the conspiracy in the treacherous palace battle. In order to protect her, the prince resisted the imperial power, exposed the truth about the murder of the entire Lin family, and avenged her. This fate that began with sacrifice ended in mutual salvation.
