I loved this drama. I thought it will typical story of a hero and his life. But it is very different as every character is important and all are interconnected. Every scene is great and has deeper meaning which we get to know as the show progresses. Its great when a show treats its audience as intelligent people and lets them ponder on why and what happened instead of just pushing its scenes into our minds. And this show gives the story the same way as an intelligent viewer would expect and even more. Please watch it and you will love everything about it. Especially Ji Chang-wook ! he is a revelation to me and now i m sure he can handle any character with ease and connect in a special way with the viewer. Great acting by whole cast and music is another plus !
