I just don't know why there is so much negative or low rating of this drama. I just finish the whole series today. I would like to say its worth watching. It really got me hooked. I have watched nearly all the popular k-drama, c-drama this year, but I would like to say that this is one of the best series this year. Scenes are not too cliche, sometimes unpredictable. I would agree that some of the acting could have been better, but OMG one of the best line-up. There's T-ara, SF9, U-kiss, ATEEZ, IOI (pristin), what could I ask more Idols acting Idol drama. Seriously, you guys out there who gave this a low drama really need to revisit and watch the drama again. Its worth watching.
