First of all the original Korean movie is just better in every way except one. The drama did the school life part better. They showed how K and Cream fell in love. That was missing from the movie. But the movie was more emotional. Although I liked the Music Producer's relationship with the assistant in the drama but most of the new storylines they introduced didn't benifit the original story at all. It slowed down the main story way too much. I also didn't like the changes they made to the original story. They basically copied "Uncontrollably Fond"s ending and put it in here. The actors did a pretty decent job but they're nowhere near the level of the actors in the original movie. The show started out great but they convoluted the ending. It would have been much better if they stick to the original story.
