I have watched all three adaptations of this drama and they all have their moments. What I really liked about this adaptation is that we can see the growth of the FL and the ML relationship. The support couples didn't really distract from the leads. The FL was caught up in her love for the ML but gradually we saw where the ML feelings grew. Unlike in the other adaptations, we saw explicitly how he felt towards his FL. He spoke about his feelings, we got to see intimacy between them and how they became comfortable with each other over time. I must say, I liked that they kissed whereas in the other two adaptations, I don't think they kissed any at all. And I really liked that all the couples had happy endings (for the most part) and their life after the orchestra.
The only downside I found in the drama was the music. In the Korean and Japanese adaptations, the music was extraordinary and that's what pulled me back time and time again. In this adaptation, the music was really lacking. Their was no connectivity between the actors and the music. Other than that, I really enjoyed this drama. I'm not particularly sure if I would watch it again though but it was worth the two days I took to watch it.
