I love this Kdrama because was different, we can see different kind of loves, the young Love and how is passionate and selfish withoute 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 someone don't like how end up things just remember how selfish was Sun Oh, in first episode, when he knew that he best friend love her, was a game for him in the beginning to Challenge Lee Hye. Sun Oh was selfish and not a good friend ,he have to pass a few stages in life and will become more grounded and mature. In the other hand Lee Hye when he finds out about Sun Oh and Kim Jo Jo he stepped back and has the patience to love her and be in his friends side, when the time comes Sun Oh doesn't do the same for him. This Kdrama sends a lot of messages one of them is don't judge someone only about how the way he looks. I know Sun Oh was cute and handsome but Lee Hye has a loveable character and was the right person for Kim Jo Jo. Sorry for my bad English I hope you understand what I mean.
