I see negative reviews, but I seriously believe those people who gave negative feedback didn't even understand the story or watched it till the end.
Yes plastic surgery is bad, yes its not good to look down on people who are fat. But don't assume this drama is basically promoting the idea that its good. It isn't, and you have to watch till the end to see the full picture, full story.
By judging the drama from the beginning without watching the story is no difference from people who judge someone by their looks. This drama has a story and its very interesting, everything about it tell's a story.
