i loved every single think abou this drama yeah to be honest in the start of the series I hoped for the Human to be the good one because come on that was a robot he doesn't have any emotions so how can I get affectionated to him but but but....I ended up to like the Robot than the human yeah because the human version of Nam Shin ws a trash in confront of him the artificial version was an agel. Kang Seo Joon protrayed very well both of the roles yeah he did suchh agreat job i just hope to see him in some great project i the future
At the end of the drama I almost had a hear attack becuase something happened, that's on you to find what it is...because if I reveal it here will be a spoiler....
