Su Zhao, a talented man from a poor family, was admitted to the harem by the emperor Xiao Chengyu because of his poem "Ode to Cold Plum Blossoms". He originally thought he was an acquaintance of "Han Mei Ying Xue", but when he first accepted the favor, he was involved in a murder case by a party behind him. She worked step by step to prove her innocence, but found that the emperor's "preference" was just a pawn to check and balance the previous dynasty - first, the sister-in-law faked her death and returned to the palace to recognize each other, then the prince died in infancy and was falsely accused and cursed, and even the most trusted female official in charge turned out to be a spy from the enemy country. When her knee bones were cut out in the cold palace on a snowy night, she was shocked to realize that she had already become a game within the game; and the emperor who once crushed her inkstone and said that "literati are sour" used blood as extradition energy to stay alive when she was dying, and was so paranoid that he wanted to "lock her in this palace for the rest of her life, and she was not allowed to leave even if she was in pain." The sadomasochistic love is mixed with the reversal of power in the former harem, from Yeting to Fengyi Palace, from being used to counterattacking, Su Zhao spent half a lifetime of heartache teaching Xiao Chengyu: sincerity is not a trade-off, but the fatal redemption of "I would rather you betray me than die."
