Really enjoyed this drama. If you are a fan of Yoon Sang-Hyun, as I am, this drama is required viewing. The role of Heo Tae-Joon was pivotal in launching Yoon's career in acting. I thought all of the actors were very good. I even wanted to hug Kim Nam Joo, so convincing she was when emotional as wife Ji-Ae. The story was involved and moved well. The first few episodes seem very banal but the plot does get more complex as the lives of four couples are fleshed out throughout the story. I think this drama is underrated in drama land, as there isn't much mention of it elsewhere and mine is the first review posted on MDL.
