Despite his genius intelligence and his spirit of fire, Lee Sun is a member of one of the lowest working classes in Chosun society. For his first ever historical drama role, L will be showcasing acting in a role very different from his previous ones. 

L said about working on 'Monarch', "I am honored to be able to give my first shot at a historical drama through such a great production. The set of 'Monarch' is a place where I can learn from the sunbaes I respect so much by watching them pour their hearts into acting from up close." 

Meanwhile, 'Monarch - Owner of the Mask' tells the story of a crown prince who fights against a powerful organization opposing the royalty, and stars Yoo Seung Ho, Kim So Hyun, Yoon So Hee, and more. It premieres May 10.
