Elixir of the Sun 

Bayan is an outcast amongst the Siyo, a people who have healing powers. Considered worthless because she doesn’t have the ability to heal others, Bayan is sent to the court of Dhan, the Great Sun Emperor, who is cursed with unrelenting bloodlust and slaughters his concubines mercilessly. It seems that Bayan’s fate is sealed the moment she reaches the emperor’s palace and Dhan is fated to suffer from madness forever... But together, Bayan and Dhan just might be able to change each other’s destiny. (Source: Lezhin US)
