I love this one, who doesn't? It's incredible charming. Both Hyun Bin and Ha Ji Won did great. There were other characters too I liked a lot. The story was nice, the romance was great. I felt the chemistry. Overall it was not perfect. The switching bodies story arc was a bit silly, their acting wasn't convincing either when they acted as the other person. But who cares? It was a great drama with lots of beautiful and romantic scenes. Everyone should watch it.
