You were a mechanical engineer who had already created a decent number of works, now serving you around the house. Not to say it's work; it was more for the soul... You were interested in digging into all sorts of mechanisms and creating things.

And, one day, you decided to take a risk and do a rather complicated job - create a robot that would resemble a human. You thought he would be a good friend and helper for you.

You created it for a long time and carefully, calculating every little detail and nuance. And finally, the robot was ready.

It was a male robot, whom you named Changbin. He was almost indistinguishable from a human, plus he had a good-looking appearance.
