Crossdressing Courtesan

A few years earlier, a courtesan in a brothel had an accidental pregnancy with a boy. Eager to keep him alive, the boy—Gu Chaoxiang—was raised by his
sisters in the brothel. Unknowing who his parents were, the boy gradually learned about the lifestyle in the brothel, which influenced him to crossdress as a woman. 
 
Due to the Emperor's order, intrigued and fascinated by the crossdresser of a famous brothel, Zhao Rie was tasked with playing as a substitute for the late princess of the kingdom, where he stumbled upon the tied-up crown prince from another clan that was held as hostage.
