I just want to say that I cannot see a drama as good as this releasing in the future. This is truly a masterpiece of a drama that I cannot even think of words to describe it. There are only a few dramas where every second truly counts and there are absolutely zero fillers. This is one of them and it is a tragedy that there are people that didn't watch this drama.
The story is the best I've seen in any drama and each character is unique and important in their respective ways. By far the best villain I've seen in any drama. This is also one of the only dramas that I've watched that has a clear moral of the story and clear theme.
Each actors played their parts perfectly and I have nothing but compliments for all the cast. If you are a Lee Jong Suk fan and haven't watched this drama, then you aren't a true fan. This drama was literally the birth of Lee Jong Suk but I think Lee Bo Young and Yoon Sang Hyun acted the best.
Music is indescribably nostalgic and very fitting for the drama.
The only flaw in this drama is the fact that it isn't the most realistic drama. Also I didn't cry watching this drama but that is only because I am not the type to cry when watching something.
Overall, I cannot rate this drama below 9.8 because it is truly a cream of the crop drama. If you haven't watched already, then I urge you to try the first episode and continue if you like it. This isn't the drama where the plot gets watered down as you watch. All the way until the climax, you will experience a serious, thrilling, comedic, suspenseful, and romantic drama that you will learn something from.
