This drama feels and looks too modern for the period it's set in. It may be more of an idol drama, but it could still try harder.. The kpop songs don't help either.. For now I've dropped at ep 3.. this may just be personal preference, don't let this stop you from watching it
ep 6 - after reading all the comments I'm not sure if I should continue T_T
for now I'll put it on hold (at ep 9) and go back to watching my father is strange instead. I was looking for a more fast paced story while watching that more slice of life drama, but I think I'll go back to it lol
