For me, this series was mainly about the way human beings find it difficult to communicate in relationships as well as the dating versus marriage conundrum. It was interesting to see how S Korean society is adjusting (or not) to declining birth rates and an eye opener for me about a lot of other pressures playing out on women. I thought all the cast were good and all the main male and female players had interesting roles.
If I have one thought for others watching, it would be that it looked to me as though Lee Min-Ki was directed to act as someone with a diagnosis such as social anxiety disorder or OCD. This so affected his character's ability to converse with female lead Jung So-min that most of their episodes were barely producing an improvement in their "no touch marriage". So be warned that you will not automatically warm to these characters. I thought the script and direction gave a very hard task to the lead couple and I applaud them.
Would I recommend? 100% yes.
