Mortician Shen Zhao was possessed by the ghost king's remnant soul and became a taboo existence that was half human and half ghost. The only person who could touch him was Bai Shuang, a trainee makeup artist who was born with yin and yang eyes. When Yin Jiuye, the traitor of the Yin Division, uncovered the conspiracy of the underworld that had been buried for thousands of years, it turned out that the seven-year-old orphan Xiao Man had the same soul as Shen Zhao, and the whispers of the female ghost Liu Manniang in the mirror were tearing apart his sealed past life memories word by word - he was the ghost king and her destined husband.
