I watched it by accident. Until then i never knew han hyo joo existed. Even then i watched shining inheritance first episode and she was in it and i dropped it as it was slow and she was not looking good in first episode. Back to spring waltz, first few episode was slow but han hyo joo beauty made me watch episode after episode. But i really hate the ending. I prefer it open ended ending in that she never love the main lead again. Also i think they made the story such that he got the money to pay for her surgery by getting adopted is cop out. This drama has to end sadly for it to be great. But overall i loved the color of the drama and han hyo joo smile and tears.
