It's for sure one of the best drama I've watched! It has a great plot, great acting full pf plot twists. Every single episode makes you feel totally drawned into the story with lots of action and an atypical romance to fulfill the more soft watchers needed. My only problem with this drama is the ending of it. Not all questions are answered so you can fill kind of lost or even abandoned by the writer. Anyway, besides this little trouble at the end, is a must watch drama for sure!
