Having never seen any other version or read the manga, I can only review based upon my enjoyment of this show. Let's start with the positive - the music. Absolutely beautiful classical music, which wove itself seamlessly through the show. For me, that's as far as the positives went. I suppose the actors did a good job, but the two main characters were not likeable throughout the entirety of the show. She was a stalker, hanging on him, liking him for no apparent reason. She was an odd woman, trying to be cutesy at times, troubled at others. She irritated me throughout. As for the male lead, he wasn't likeable either. I understand that he had trauma in his life, but that's not really an excuse to be so mean, especially to her. I didn't feel that the relationship was believable at all. There was no chemistry between the two, even at the end. By the time this show ended, I was so frustrated with the amount of time I had wasted. Park Bo Gum's character was more likeable, and I felt that she and he were much better suited for one another, because he didn't want to change her.
