I am really disappointed. The story progress was the most boring part, it just made me mad. There was also too much music, almost made me want to watch the drama without the sound (im not joking, there was really a lot of music). Yes it is a drama about kpop trainees BUT it is not necessary to play OSTs EVERY SINGLE MINUTE !!! Imma be honest, the acting wasn't that good either (except for Kim Yoonwoo), i didn't feel the emotions, the feelings, i didn't feel ANYTHING. The actors are cute yes, but the looks don't do everything.
