Loved this show!
Very good side characters which provided some additional dimension to the show. Having these characters made you root for some, hate some, commiserate with some and empathize with some of them.

I am partial to Jung So Min as she is one of my favorite actresses. I think she is a very good, natural actress who can do justice to her roles. She's not very over the top. And I disagree with those who said she is so stiff in her role in this show. The role calls for some stiffness, she had to be stoic in certain situations. She is guarded, not stiff.
Loved the secondary couple - Mr. Ma and Soo Ji. Ho Rang was okay and their couple story-line also showed some other aspect of a relationship . LOVED Bo Mi! She is hilarious with her deadpan delivery.
And the Mom's wedding letter will forever be the most touching Mother-Daughter scene for me.

There were a lot of quotable quotes that I will definitely jot down once I re-watch, so yes to re-watch value!
