Let's just start of with the fact that I've watched this drama 5 times and I love it more and more each time it is perfect. After this drama Gong Yoo became one of my top 5 actors of all times. It is a great story, with really good actors, hot sexy eye candy, and a great chemistry between the leads. I can honestly say that I really thought the leading girl was a boy. Even though the story seems a little out of the ordinary like "there is no way that something like that could happen in real life" the way the actors portrayed their characters you really could believe that was an everyday thing. It toke me untill after the 3rd time I watched it to realize that it really is fantasy you really would never have tought of it. It's cute and funny you just have to watch it you are going to fall in love with it.
