In lieu of the more traditional form of review, this author humbly submits the following questions:

Why is Hwang Min Hyun a more expressive actor when he is wearing a mask than after he removes it?

How many subplots can be introduced and left unsatisfactorily unresolved in a standard length drama?

Of the many dramas where one of the main characters is an idol, are there any that are actually compelling, complex characters? Why does an industry that is so heavily populated by idols so poor at portraying a fictional version of one?

Has anyone checked the family register of Hwang Min Hyun and Kim So Hyun to determine if they are siblings because if they were, that would at least explain the complete absence of heat in their shared scenes?

Since he didn't through the entirety of filming this show, does anyone know if Seo Ji Hoon has demonstrated any sort of emotional expression since production wrapped?

Has any paparazzi ever cared a whit about an artist who was strictly a songwriter?

Have the agent and casting director who thought Seo Jung Yeon should play a stonefaced, emotionally stunted assemblywoman been sealed in a homemade submersible and dropped to the depths of the Pacific Ocean yet?

Where does Park Kyung Hye rank among the legions of supporting actors that play the mischievous comic side relief best friend of female lead? All hail Queen Park Jin Joo obviously, but how far down the list after her is Park Kyung Hye?

Which creepy K pop agency CEO is the closest real life facsimile to Yun Ji On's Deuk Chan?

None of these are questions that really need to be answered because this is a show that the less it is thought about, the better. A point for novel concept and a strong soundtrack (if that matters) but everything else that followed was lacking. Not recommended.
