The modern girl Xue Qingyin accidentally slipped into the ancient novel "The Only Favorite Princess" and became the female supporting character who was destined to die miserably. In order to change her fate, she gave up her entanglement with the male protagonist of the original book, and instead approached Xuan Wang He Junting, who was destined to be buried in the sea of fire, planning to use his power to save her life and become a widow. However, the "love" she deliberately showed made the cold-hearted He Junting mistakenly believe that she was sincere, and she gradually showed an unknown gentle side. As they get along with each other, Xue Qingyin relies on modern wisdom to gain a foothold in the court, transforming from a marginal supporting actress into a celebrity in the imperial court. When the mystery of He Junting's life experience was revealed - he was actually the son of the former prince who was wrongfully murdered, Xue Qingyin became his strongest support on the road to revenge. Facing the "crematory for chasing his wife" from the male protagonist of the original book, she has made up her mind. In the end, the two worked together to rewrite their destiny. He Junting ascended the throne as emperor, and Xue Qingyin became queen. From "each taking what he needs" to truly loving each other, they created a legendary love.
