Just catched up with this drama. I avoided it at first because I thought it would be a tearjerker only. Well it was at times but it also has some good sub plots with some good action. Despite the know it all side of the ML (Yes Han Geu Roo is the ML) which is annoying at times, he is still genuine and his abilities help a lot. SML Cho Sang Gu is a loser but he has a proper character development and his story is interesting. Yoon Na Mu is not only the fifth wheel of the carriage. She was funny and useful at times.

Binged watched the whole serie within a week-end. Quite an emotional and well crafted serie which denounces fairly some bad aspects of SK's society/history.
