The Face Reader

Nae-kyeong is the greatest face reader Joseon has ever known. He can see through people by looking at their faces. After moving to the capital to read faces in the courtesan house, Nae-kyeong quickly becomes the "go-to face reader" in town. Upon finding out about Prince Su-yang's plan to take the throne, he decides to change the destiny of the country by changing what's written on Su-yang's face.
