The plot is simple and that is one of the reasons why I find the show to be beautiful. I love the show, because of what Van represents. Protection, patience, and sacrifice, but also the pain that comes with those three things. Van is half human and half demon, but has always kept his humanity. Mi-Ho looks at Van, sees the human in him, because that is what he projects. The human in him. The way he looks at her, is the most beautiful thing I have witnessed in a show. What that marble represents inside of her, and how he has to return the piece to Mi-Ho is very profound. That part broke me, because since the moment he became half-demon he waited for the day he was not. He knew that was unatanninable, so the only way evil would disappear was if him and Gungtan were to not exist in this world anymore. He had to disappear. It broke me, because I have found a character in a show I liked more. The way Kim Nam Gil portrays Van is both heartbreaking and hauntingly beautiful in my opinion. His eyes are very expressive, and because of that he does not have to speak. You know what he is thinking. I could say more, but I don't think I need to. This is just a really good show in my opinion. :-)
