The episodes are riveting and thought provoking. The main actress acting is excellent. I’m not sure about the two cheating Robots. Do they have to act in a one dimensional way?
The side plots do not have anything to do with the main plot. Is it just to make the story longer. This is what’s wrong with KDramas. It drags the whole 15 episodes only to rush the resolution in the 16th, and then the ending isn’t executed well or executed poorly. You end up thinking “why in the world did I waste my 16 hours of my life.” But hey, I participated so my fault. This story better make sense in the end. A drama like this should at least make you feel good in the end.
