In her previous life, Shen Wan fell victim to the power struggle between her aunt, the Queen Mother, and Emperor Xiao Che, and died in a glass of poisonous wine. Reborn at the age of sixteen, she was still the niece of the Queen Mother who lived in the palace and seemed to be weak and vulnerable. This time, she is no longer naive and vows to avoid Xiao Che, escape from this man-eating palace, and find out the real culprit who killed her in her previous life. However, the trajectory of fate has shifted. The emperor Xiao Che, who was indifferent and distant to her in his previous life and eventually gave her poisonous wine, showed unprecedented persistence and tenderness to her in this life. He saw through the fear and alienation beneath her disguise, pressed on her step by step, and protected her firmly under his wings. Shen Wan is faced with a dilemma: should she believe in the completely different Xiao Che in this life, or should she stick to the lessons of blood and tears in her previous life and continue to escape? At the same time, the villain's agent, the Queen Mother, who is kind on the surface but extremely controlling in reality, is secretly choosing a husband's family for her that is far away from the imperial power, intending to send her out of the palace as a pawn in a political marriage. This directly hinders Xiao Che's actions. Shen Wan carries a fatal secret - the identity of the reborn person and the prediction of the future. Once exposed, it will definitely lead to death. Under the threat of a countdown (the Queen Mother is about to make an engagement for her), she must use her past life memories to deal with the relationship between her aunt and the emperor. In the pull of the emotional triangle (Xiao Che's strong protection, the pursuit of the "beloved" arranged by the Queen Mother, and her own inner fear and throbbing), she must discern her true heart, rewrite the fate of herself and her loved ones, and avoid the bitter victory of repeating the same mistakes.
