Interesting plot and storyline. It's a challenge to play two roles in one person and Kim Soo Hyun had showed his confidence, passion and dedication in achieving the great performance especially in differentiate the extreme characters between the two roles, which was very convincing; and of course his professional in those sexy moments. The scene shooting was awesome, though the final gangsters gun shooting scene could be more creative, in order to build up the final part in more artistic way which make the ending echo.
