Story: I felt the drama had no defined, real story. I also felt it was all over the place since it didn't feel consistent. I actually skipped a bit towards the later episodes. Acting: It was just OK (though some were less than OK), but to be honest I had hoped that Kang Sora would do a better job since she was one the actresses in the group. I did like JinWoon, he did better than I had thought he would and I, also, liked Jung Yeon Joo's character and her portrayal of it. Music: The music was great. For me, it was the best part of the drama. I loved the performances and the preparation scenes which took place before them. I also liked the "non-competition" music scenes. Re-watch: I do no plan to re-watch this drama since I found it lacked a lot and I can just search for the clips involving the music parts, which is the reason why I even rated it a 5.
