Master of the Wind and Moon

During the Silla dynasty, both male and female gisaengs fill the halls of Unru, a brothel located on a mysterious island shrouded in fog. It is here that two longtime friends, Yeul and Sa Dam, begin to explore their feelings for one another. But one day, Queen Jin Seong has her eyes on Yeul and selects him to be her King, asking him to enter the palace.
