This was my 3rd Korean drama and I was glad it was so good.
Loved:
* Actors - good acting, cute
* OST - the songs have been on my playlist for many months now
* Romantic tension was just right

Didn't love:
* Several plot lines. They had a purpose but sometimes it dragged and when I was vested in one story it switched to another story
* Poor 2nd lead. I don't know why I still feel some type of way about this.
* The mom - she was abusive, it wasn't funny and didn't add to the story.

I got my daughter's friend hooked on the show and got an earful from the parents because she was watching so much tv. We thought it was worth it.
