For me, it is a 4.5 stars drama, this is my third ever drama after World of Married and Sky Castle. I love it how the drama shows the close real situation of how North Korea and South Korea situations are. It get so intense in the first 1-10 episodes as we keep thinking what will happened to Se-Ri later on, but what makes this drama lost their 0.5 points from me is because there are a lot of useless and weirdo scenes in the episode of 12-15. E.g: When Ri Jung Hyuk (the person who always looks strong and firmness) in the character suddenly become " childish " when he visit the South by playing computer games in Se-Ri house and doing some silly things, for me the scene really drop down his honor as a " strong man ".
