The modern Xue Qingyin accidentally traveled through time and became the tragically fateful female supporting character in the ancient novel "The Princess I Love". In order to change her destiny, she gave up the male protagonist of the original book and approached the ruthless King Xuan He Junting, hoping to use his power to save her life and become a wealthy widow. In the early days of marriage, she pretended to be coquettish and naive, causing He Junting to misunderstand that she loved him deeply. He Junting gradually showed tenderness and doting. Xue Qingyin relied on her wisdom to gain a foothold in the court, from a marginalized female partner to a celebrity in the imperial court, and He Junting also regarded her as his light. Later, He Junting's life experience was exposed. He was the son of the former prince who was wrongfully murdered, and he secretly plotted revenge. Xue Qingyin became his "heart protector". The eldest brother who was once admired by Xue Qingyin started "chasing his wife in the crematorium" after she changed his heart, but was rejected. He Junting is in danger of being discovered in the process of revenge, and the palace environment is also hostile to Xue Qingyin. In the end, He Junting succeeded in clearing the emperor and ascended the throne of God, and Xue Qingyin became the queen. The two went from getting what they needed to truly staying together, rewriting the tragic ending of a double death.
