This is just an awesome Drama, it kind of gives me Descendants of the Sun and The King 2 Hearts vibes. The Acting is absolutely amazing there are a lot of good Action Scenes, Drama and a lot of Romance and the Cast is just perfect. I Love Big Boss from Descendants of the sun but Hyun Bin as Ri Jung Hyuk is just Chefs Kiss. He is an amazing Actor and I really cant wait to see more in the future. Maybe again with Son Ye Jin as a Couple cause their Chemistry is impressive. I really liked all the North Korean Soldiers and Se Ris Secretary and his Friend.
