The first thing I'll mention is the acting was top tier! All the protagonists did very good. Though some plot holes can be found, the storyline seemed engaging to me.

It shows us problems after marriage. Extramarital affairs. A couple takes advantage of cheating married people. I liked it as they were not targeting innocent people. But in the end, they turned out to be one of them.

I didn't like the last episode much. Lived Samuel, I think he was a perfect husband despite of his attraction towards min soo. He was so good to his wife. But I'd say Woo Jin took him for granted.

As it has only 6 episodes, it's good for binge watch.
