I really enjoyed this series. It's a very interesting plot that makes you contemplate what it means to be human and at what point would you start seeing/treating AI as such. Also what place they could possibly hold in society.

Thsi was also my first introduction into Seo Kang Joon. He played Nam Shin 3 with such innocense and heart that you really start to feel for him, even though he is 'just' an AI robot.

First I was worried for the ending, because K-drama's usually have 'realistic' ending where regular westerns shows mostly have a romantic ending. It was realistic, but still enough to satisfy the romantic in me. Absolutely worth a (re)watch.
