I really love this drama and so I will try my best to not leave any spoiler. This is one one of the best dramas I've ever seen, also as a viewer there wasn't a single moment when I felt bored or felt like skipping a scene or two. Every scene keeps you hooked to the screen and some of them might even give you goosebumps. All the actors have portrayed their characters well, bringing justice to them. Personally I liked the WAR scenes very much. They literally gave me goosebumps. For me its a must-watch if you like to see unexpected things coming all of a sudden.
