To be honest, I expected more from this drama. I liked it in many aspects, but the story... For me, the only reason I watched the whole 20 episodes was the cast. Acting was so high that I decided to be patient and tolerate with such a cliched plot. So many times I was crying 'WTF?!'. I was really surprised that main characters didn't turn out to be brother and sister and none of them was suffering from cancer. Nevertheless, I was glad that completed it, because the final was quite strong. If you watched 'That winter...', you will understand my feelings. By the way, both dramas have that changing from fake feelings to true love. But 'That winter...' is more realistic, I suppose. In 10s of XXI century I can't bear with Brazilian soap operas' plot twists. I admire the fact, that koreans are progressing so fast in making good dramas, but they still have a lot things to improve. As for actors. It can't be denied that Song Joong Ki did a great job. His changing during the story was so striking! He is now one of my favorite asian actors. I also liked the main female antagonist, Jae Hee. Her choice was immoral, but It's part and parcel of everyday's life. No doubt, you have heard of plenty girls aimed to hit the jackpot by all means. Supporting characters (Kan Ma Roo's friend and his younger sister, Jae Hee's brother) were great too. Drama is worth be watched (or listened - wonderful instrumental music themes!) , but still is very far from perfection.
