WHAT IS HAPPENING WITH PEOPLE?

I started watching this drama because of people's comments and I saw some episodes and I liked the story: A man who dies and his soul (in another body) struggles to get his family back; but he falls in love with the beautiful wife of his new body (whom he just met) and many people see this well because she is pretty.

If actresses swapped roles, people wouldn't think the same, I don't care about the ending. It's a superficial drama: A man who loves his family and his wife contemplates leaving them for a rich family and a beautiful wife he just met.
