A murder occurred in Anguo Temple. The general's beloved concubine died, but the prime minister's concubine survived by chance.
Shen Xing, who survived, found that he had the memory and affection of the deceased Wu Yue. When the fates of two women are intertwined in one person, who was the blade in the dark pointed at in the first place?
And who is she? Is it Wu Yue who was reborn through reincarnation, or Shen Xing who was occupied by memory? In the fog, two mysteries of life experience, an unsettled feud, and a misplaced life are waiting for an answer.
