Brothel Le Kui x Royal Illegitimate Son
Bai Yanqiu, an orphan from the previous dynasty, transforms into a brothel musician and plays the moon, delivering the secret message of national restoration with the music of the piano; Shen Qingyan, the illegitimate son of the royal family, forms a clique and seeks the throne in the name of romance.
The two fell in love and killed each other in the game of musical code and intrigue, and finally discovered that each other's fate had long been bound by the loyalty and betrayal of their fathers - they were old enemies and each other's only antidote.
