I found the premise of this movie very interesting, but because I knew it would be an emotional rollercoaster I put off watching it. It was a rollercoaster emotionally, but I found Lee Jun-ho carried this film. The romantic scenes with Won Jin-ah were forced at best. Won Jin-ah looked like she was a wooden statue & Lee Jun-ho was doing his normal kissy self. Now I know he excels in this area but his romantic partner made it painful to watch. I find it silly that they portray adults as virgins, it just doesn't fit. I am not all about romantic scenes I could take them or leave them but if they take them make them believable. Lee Ki-Woo brought nothing to this film except a wonderful walk. The part could have been played by anyone. On the other hand all the older actors in this film were fantastic & since that was a central part of the film, it really made it what it was again an emotional rollercoaster.
