Basically, I recently rewatched this drama after a long time. Around 2014-5 I first saw this drama after having seen the original Japanese live-action (which I really liked). From what I remember, the Korean adaptation is quite similar to the Japanese. Let me first start off with the story, I haven't watched many dramas on classical music, so I found the story to be somewhat fresh and interesting. I wonder if the actors actually played those music instruments..not important I guess, since it they defintely looked like they were (total music instrument layman). The actors were casted quite well some could be a bit better (Joo Won's mom whom I liked but their development was lacking). Some acting by the lead actors seemed somewhat raw, especially that of Park Bo Gum (which I didn't even knew the first time I watched it) and Joo Won (who has acted a variety of roles, really liked his acting here). Shim Eun Kyung role shouldn't be taken too seriously. An appreciateion point found in the drama is personnal development of the characters. The overall background music fitted well (all classical music).

If you are searching for somewhat fresh, funny and somewhat older friendship (and music related) drama, try it out! Hopefully you will enjoy it as mush as I did.
