I love this kdrama because was different , we can see different kind of loves , the young Love and how is passionate and selfish without looking who is who ,and the adults Love when you find a person who is the right for you and you have the same values, dreams and struggles. If some one dont likes how end up things in this drama just remember how selfish was Sun Oh, in first episode , when he knew before ever met her that his best friend love her, was a game for him in the begging to challenge him. Sun Oh was selfish and not a good friend, he have to pass a few stages in life to grow up and be more grounded. In the other hand Lee Hye when he finds out about Sun Oh and her he step back and has the patience to love her and be in his friend side, when the time comes Sun Oh doesn't do the same for him. My english is bad i hope to understand what i mean 😉
