This may be a longer drama, but it is definitely worth the watch! It has action, drama, romance. It works on every level. It shows how war can change people and decisions, and how someone who seems to be beyond saving can rise to be a symbol of hope. It deals with overcoming loss and trauma, and made me really feel for the main characters. It's also a period piece that is set in a time in Korea's history that doesn't get much attention in other dramas. Though I always love Park Ki Woong, I have to say he is definitely a standout in this series. He can make an audience question whether they want his character to have a happy ending or a terrible death. The only reason I didn't rank this drama as a 10 is because since it is so long, I will be less likely to rewatch it, but this is an amazing series that you won't regret watching!
