The main thing that I had against this drama was that the plot was all over the place and there were too many loose ends by the final episode. To me, it seemed like the script writers were trying to cram everything into the last episodes but there were so many filler episodes before it (imo). A lot of things were brought up near the end of the drama but were never fully explained. And in my opinion, there was wayyyyyy too many conflicts and random things happening during the drama that it was not very fun to keep up with it. Honestly the only reason why I kept watching this drama was because of the acting; casting was done very well but most of the characters didn't get much character development throughout the drama. The only character that I didn't like very much was SeYi; her singing style didn't really fit with the rest...imo...not my style at least. Also, I didn't really like her character either (I thought she was a little immature).
