I was looking at the apparent ages of kids and adding them up, and realizing that the 3 older ones had to come about a year apart at the most.

I think it bordered on saying the countryside was better than Seoul, but barely saved itself. Not vilifying Su Jin-the cuty girl trying to lure him to the city-helped a lot, and they had Ji Hyun become a fashion designer again, which was a nod to her city life still being a part of her.
