This drama is my no.1 favorite drama, but the first time through it was about no. 7 or something.Sometime after the first watch, I was in the mood for something with a little depth. Secret/Secret Love is a little more serious than I like but it has a really satisfying ending... so I re-watched it. And then I re-watched it again. Each time I moved it up on my favs list. I finally had to admit that this is the best drama I've ever seen. I am not usually a fan of the more serious dramas. It was so dark in the first few episodes I almost quit watching it around the 6th episode... but I am so glad I hung with it, because it got so good after that. The story is really compelling, and I love how they reveal bits of the story as the lead characters are finding them out. I know I am not alone in hating misunderstandings in Dramas. I get so frustrated when you know character A never did what character B thinks they did, but it takes 3 episodes for character B to find out. In this one, everything everyone is doing makes sense based on what you know at the time. The acting is amazingly good. I hated Bae Su Bin so much after this drama, I had a hard time seeing him as a sweet character after this drama. I am sure that is a compliment to his acting, although, I found him a bit over the top in a couple of scenes. I became a fan of both Ji Seong and Hwang Jung Eum after watching it the second and third time through. Seriously they deserve Oscars(or whatever the equivalent award in Korea is) for their performances. The scene where she crosses the street to get away from him is so good. I recommend this drama to everyone. Watch this when you want to be completely absorbed in the story and characters. It is not light viewing.
