Main plot: Su Jinli, a concubine from the General's Mansion, was sent to the palace as a pawn by her family because of her resemblance to her sister-in-law Su Jinxiu, and became the substitute concubine of the crazy tyrant Xiao Jue. Everyone thought that His Majesty was deeply in love with the frail and sick Bai Yueguang Su Jinxiu, so Su Jinli suffered all the cold eyes, torture and humiliation from Xiao Jue in the palace. While he acted like a couple to her, he cruelly warned her that she was just a fake. However, no one knows that it was never Su Jinxiu who played chess with the young Xiao Jue under the plum forest and amazed him throughout his youth, but Su Jinli, who was covered up in all his glory. When the conspiracy was uncovered layer by layer and the truth came to light, Xiao Jue was shocked to realize that he had personally pushed his beloved into the abyss. The substitute that he had abandoned like a piece of shit in the past suddenly turned into a cinnabar mole that was out of his reach. From then on, the ninety-five-year-old emperor embarked on a long road to pursue his wife, repenting every day and praying every night, just to have her look back at her once.
