I thought this drama was great, honestly. Yes, the first two episodes are kind of lack luster but once the drama picks up I think it's awesome. Nam Joo Hyuk's acting is so good, his face is great at conveying emotion so it really tugs on the heartstrings. Gong Myeong was great, as was Krystal. The OSTs could have been better, but I usually don't think about those. I thought the ending was great as well. It takes a lot to get me to cry at dramas now that I've seen so many but this did a great job. I believe that the people who are writing poor reviews are because they didn't really watch it at all.
