This drama is an extremely emotional one, so those looking for a lighthearted romance should avoid it. I would definitely file this drama under tragedy, so keep a box of tissues close. By the end of the first episode, I knew this drama would not hold back. The story involves longing, betrayal, revenge, secrets, family ties, and ill-fated love. The cast does a good job of balancing really heavy scenes with funny, and sweeter scenes. Im Su Jung was so good as naive Eun Chae, that she made some of the more over the top moments completely believable. The same can be said for the rest of the cast, including Lee Hye Young's character who I loved to hate, and showed unexpected depth. My absolute favorite was So Ji Sub. He really played his character brilliantly. He did so much more than just cry, yell, and laugh on cue. As Moo Hyuk, he showed so many complicated emotions, and I could never predict how Moo Hyuk would react. During moments in the drama that started to feel a little repetitive, he always pulled me back in. The fact that he is visually appealing didn't hurt either. The plot does have the privileged vs the poor, and love triangles/squares, which is expected in most dramas, without following the same path. Every time I felt the story becoming predictable, a new revelation would catch me by surprise. I also could not predict how it would all end, which was refreshing. Some of the down sides to this drama, to me, was the laughably bad english (so distracting), Yoon's terrible singing (also distracting, since he was supposed to be a pop idol), and showing way too many flashbacks. Later episodes seemed to rely on flashbacks to fill up the time. Some scenes were repeated so often that I no longer needed subtitles to understand them. Still, I never felt like dropping this drama after becoming so invested in the characters, and what would happen to them. I think the positives heavily outweigh the negatives. So Ji Sub alone would make me recommend it. The soundtrack was good, and included some random songs like Billy Joel's "The Stranger" (which was a perfect fit). I don't know if I can stand emotionally to rewatch the entire drama, but It's so good that I might.
