The plot line was mediocre. The acting was nice and I especially liked the songs. The idea was good, but I think the producers could've done better. When I first read the summary, it sounded pretty nice. I guess I just had high expectations. There was not a drama whatsoever, there was no excitement. They just exchanged a few notes and that's it. What I most liked about the series is the supervisor's encouragement. The purpose of the supervisor is not to scold you or basically make your life hell. He should encourage you to do your best or to point out the weaknesses in your work and help you get over them/ help you improve. The series teach the value of moral support - whether it is your manager, your neighbour or roommate. That was the best part of it all. As I already said - I find the acting and the overall idea pretty nice, it was thoughtful, but a little underdeveloped. I do not think that I would rewatch it.
