I went in without any expectations and was blown away by this drama. The acting is outstanding, especially the performance from Nam Gung Min as Nam Gyu Man. At no point did I feel like the story dragged. Every action and plot-line feels important even if they don't directly concern the main plot-line. This is a story that kept me guessing what would happen next and most importantly had me cheering for our main character. The music is also outstanding and adds to the story.

In summary: well acted, well written, great music. I cried. Recommended.
