firstly, this drama moves slower than others. It's not rushed though on the other hand it's not dead.
I appreciate that in a sense, sometimes the story of dramas moves too fast For you to take it all in - so it's a welcome change.

If you dislike drama for the sake of drama and tumultuous relationships then you are in for a pleasant ride. What I liked most about this drama is the fact the main relationship was steady, cute, not controlling and honest. i could have watched them for 16 more episodes as they grew musically together.

something I would have liked to see was a change up on the song performances. I know that writing a song is a difficult process, but having heard them play and sing the same song the entire time made me slightly bored.  Joy's voice was amazing though.
