The reason is that it felt superficial and like it was making fool of the viewers. It didn't stir up the emotions I was expecting to feel from a stressed single mother-son bond. Maybe on paper I get it but intellectually I am not convinced.

A rather simple example to prove that would be the story of the pigs. Like the whole show the mother was preachy about how she cared about her pigs especially mother pigs. But logically if you think they were raising them to sell and have them slaughtered for food. So how am I suppose to enjoy the metaphorical relationship between the human mother and pig mother which is present throughout the drama. It is funny and a petty example, I know but I can't get my head around it (you will know how serious they were about their pigs through the drama!).

So besides this major point (haha) there was hardly anything in the script to comment. If you are an avid drama watcher then the story is guessable from ep 1 itself. The suspense element is not that strong really. The relationship between the leads thought started angsty get fuzzed out pretty quickly and there was nothing to explore. If at all the son felt too much of a mumma's boy to be enjoyed as a manly ML . As much I loved all the actors and was hyping up for the show, it didn’t deliver.

The villians again felt cartoonish not evil. Again one of the villian was supposed person with high power and whatnot but it was quite convenient to defeat him which contradicts the fact that he is like the most powerful person to beat.
I mean there are serious consequences to that in real life if the President is impreached and I know drama is suppose to be fiction but having some logic won't hurt. K-dramas needs to up their king/President characters in my opinion.

Overall I don't regret watching it and the acting was fine but I'll forget about it quickly. It recommended only if you want a filler drama for timepass.
