Heroine: Shen Qingyi (Modern Soul Traveler)
Original male protagonist: Xiao Jingheng (the cold and violent regent of Daliang Kingdom)
Original heroine/Bai Yueguang's stand-in: Su Wanqing (the late gentle and talented woman, Xiao Jingheng's lifelong love)
Important male supporting actor: Xie Yunzhou (a young man from an aristocratic family who looks as gentle as jade, but actually has a deep agenda)
The stand-in heroine was completely exploited by the male protagonist. After Su Wanqing was "resurrected", her heart was cut out and used as a drug to induce death, and she died tragically in the cold palace.
