Gu Qingyue, an older leftover girl, traveled through time to a certain dynasty's palace to be a concubine due to a car accident. As a fujoshi, she transformed palace fighting into cuckolding and successfully created a new trend in the harem. The concubines: "The Emperor and the Imperial Master are so well matched~" From then on, the concubines no longer competed for favor, but began a long road of matchmaking. A certain imperial concubine also succeeded in bending Gu Qingyue (although she was not very straight to begin with)
Concept: Concubines can also have sex
