First of all I loved the actors/actress.. it was a very good cast..The first few episodes was okay.  Then it got to where I was speed watching to watching every other two.  I have watch many many dramas, this is the first one that has frustrated me to the point that I don't even recommend it to anyone to watch.  Honestly I don't even remember much about the music which is the first for me because that is the first thing I remember about a drama.  They should not have drag this drama out for 124 episodes.  I hoping the cast finds another drama that is worthy of them.
