This drama had a very cliche, yet interesting concept to it. The romance is definitely played out and spaced well. I especially loved Kim Sarang-Yoon Sang Hyun relationship. I felt that story was really interesting. However, at times I was a little disappointed. Overall, the story does go full circle. It explains what it NEEDS to; however, there were minor instances that should have been better. In fact, sometimes they just didn't make sense (I don't want to give examples as they would be spoilers). Speaking from a literary lens, there were a lot of plot holes and things left unexplained. The acting was decent. It wasn't great, but wasn't terrible. Ha Ji Won isn't THAT great of an actor, but she did have her instances where she really shined. When she cried, she had me on the verge of tears. Don't forget the body switching either. They would have to play the part of the other person which was very good. The rest of the main cast (as well as the minor/supporting) had a good fit (although I wish Jay Park was to be in it as originally planned :(..) You normally can't go wrong with the music in a drama. SBS/Secret Garden staff did not fail to execute. "That Man" was a very catchy tune, as well as some of Yoon Sang Hyun's songs. I even downloaded the OST because I liked a good portion of the songs. I'm not one of those people that judges a drama based on how much it makes them cry, the actors chosen, or something ridiculous like that. There were many small things that were left unanswered. The only questions answered were the big points (Gil Raim's father, etc.) The plot is a decent/very cliche body swapping drama. Overall, I give it a 7. I'd say it was a very mediocre - almost good drama.
