I watched cunning single ladies and from then on I've followed Seo Kang-joon..
and was never disappointed. This is a good story. highly recommend.
It is a heartbreaking story about a robot with a good heart.. Reminds me of Edward scissorhands.
The story is really touching since it emphasizes how Greed and love of money could destroy families and lives of people.
and how manipulating people through money could get back to you in a snap.
The sad part here is how a mother who longed for his child created a robot to help her cope with the sad feeling of being apart from her son.. and later on sees how his real son had become.
