Story:
Great drama. The storyline is interesting and heartbreaking. I really enjoyed the clown acting as the King. I did like the interactions between the clown and the Queen, and their love story was sweet and heartwarming. The political aspect is good, they didn't drag it out for too long. What I didn't like, though, was the ending. It was rushed, and to me, it is quite unrealistic. 

Cast and Characters:
• Yeo Jin Goo as Ha Sun (the clown) and Yi Heon (the king): He nailed it.His acting is phenomenal. He totally owned this drama.
• Kim Sang-kyung as Yi Kyu (Secretary): His acting is good. I enjoyed his scenes with the clown and their relationship.
• Lee Se-young as Yoo So-woon (Queen): she is a solid actor. She is beautiful and perfect for that Queen role.
• Supporting cast: I liked all of them especially the actor who played Eunuch Jo.

Music:
The music is brilliant.

Overall:
This drama is quite predictable, but it still is one of the best historical dramas out there. The storyline is enjoyable. The actors were outstanding. It is a must-watch.
