I really enjoyed most of this drama. I don't normally do revenge / melodramas but I really enjoyed the "badness" of the main male character in the first episode, so I kept watching. His thought process and planning skills kept me intrigued. The main female's character was slightly annoying, but the secondary characters were likable enough to help make everything flow well. The plot was good and I enjoyed the character development. The ending was kind of "vanilla" compared to the rest of the show. Don't get me wrong, it was fine, just a little vanilla.
