The story is cute, especially with the affectionate scene because it makes me fangirl a little.
Sadly the music playing never synch well with the actors playing the instruments. Sometimes the instruments they play aren't even the same instruments that are dubbed over like wtf?

There's some snobs that keep trying to correct other people playing their instruments but they keep saying wrong facts lol.

It's very clear that in this drama there was no serious research done and the editing team could've synched the audio better.
