It's a lovely drama. I do however think that FL's life as a housewife has been too dramatized without any actual reason... I mean, she got married at the age of 25, and then had a kid at the age of 35 or 36?
So, what prevented her from having a career, clubbing, or whatever she wanted to do while young?
Why did they struggle financially if both of them worked?
There are some inconsistencies, but all kdramas have them. Once you look past these, you can fully enjoy the series :)
