The Story I'm not Korean so I don't know much about the historical figures in the story. Despite that, the story is quite familiar since it's like the Prince and the Pauper. You get the idea. It's creative enough to make it possible for a king to have his replacement. I like how the story unfolds. The Cast This might be the aspect of this drama that I was so amazed and astounded with. It's amazing how Lee Byung-hun is such an amazing actor having two roles in this movie. It was not difficult to differentiate his two characters. It's my first time watching him so I am in awe by how you can distinctly differentiate his two characters just by his voice articulation and of course, his actions.
