Being involved in computer related industries one of my favorite themes has been artificial intelligence (AI). This drama was able to reasonably weave some of the dilemmas involved with creating advanced AI assistants /companions. Of course it also uses many of the usual kdrama plot devices to deliver an interesting show with a credible (although sometimes far fetched) storyline.

I think this will end up being one of my favorite lighter dramas. If you enjoy this drama I highly recommend the more action driven "Memories of the Alhambra" next.
