It was fun to watch and later on it kinda got "heavy". It was sort of long for me, but hey, I enjoyed it. I almost did not watch this because I was very disappointed with Lee Min Ho's - "The Heirs" - it was an over-used plot capitalizing on the popular actor/actresses and just plain dumb. No depth. So here comes this drama, I was completely entertained and as I said, it was just a tad long but did not drag at all. I just prefer watching 16 episode dramas. The supporting characters in the story really added flavor to it and made this drama more entertaining.
