It is hard to say who started the cheating premise. Obviously the guy and girl are wrong, but which one is more at fault? Along the way you get to see a lot of some-what boring getting it on scenes in different locations. What is weird is that only one of them has Um Jung-Hwa showing some flesh, as if to assert authority to the audience that she is calling the shots. Along the way Um takes photos of them together in imaginary husband and wife type of settings which the guy doesn't like at all. They even go shopping and take trips together. All of her actions make it seem like she wants to get caught, while at the same time not hoping for it. She is crazy enough to handle two relationships.

In the end there is a throwaway line where you realize the girl's lies might be bigger than the affair itself. Everyone has a point in their relationship where they go, "What if" and some might have even taken it further. This movie makes you believe that it can work while scaring you away from it at the same time.
