I can imagine that the story line is not everyone's piece of cake.
To me it was recognizable in the sense that I am married to a man with whom I have quite an age difference. Although, to my surprise, the age difference was not such a big problem to the parents as expected, I could fully understand the love couple's feelings and struggles. I have been in a similar situation. Being in love, having a joyful time together, but always having to face trouble returning home to my parents. It was really a difficult time and to be honest also something I do not forget. It was a time where you decide to break up, ... not...
So to me this was a special kdrama and I just the right actors to play the couple. I am anyway a fan of Son Ye Jin and the chemistry with Jung Hae In was super, although her chemistry with Kim Hee Ju in Personal Taste was also great.

I love almost all the music. It fits perfectly, although sometimes I had enough of listening to "Stand by your man" over and over again...
