SPOILERS
It was a good show presenting how much works that a career mom/housewife is doing which a man/husband should realize. But some Viewers may not agree with the ending story. ML and FL acted naturally and excellently in this K-drama. OST was great and so emotional.
Both husband and wife worked hard for their family. The husband was a good person and honest but did not notice that his wife was exhausted from her overworks as a career mom and housewife. The story showed the wife’s excuse in having an affair due to her overworks and the husband did not notice it … but another married man noticed it. Instead of asking the husband to help her burdens, the wife chose to have an affair with that married man to comfort her. The cheating wife could break her affair relationship any time since it started about half a year but she didn’t. She planned and intentionally lied to her husband for the office meeting activity such that she could have an affair with her lover in a hotel room but they both were caught up red-handed by the husband. She acted so calm and seemed not to feel much guilty about her affair and in hurting her husband’s feeling. Although the wife wanted to temporarily stop the relationship with her lover, she did not expect that her lover would dump and abandon her completely. She then started to feel remorseful, ashamed, and could not face her husband … but later still wanted to reconcile with the husband.
The husband tried hardly to forgive her but eventually could not - even when he wanted to hug the wife, he could not force himself to do it b/c he could not get rid of the cheating wife’s lover face in his head. The husband was hurt and agreed with the divorce proposal. Lastly, the (opened) happiness ending was ideally that the husband might be able to erase his painful memory in such a SHORT period (which normally took years or forever) and came back to her.
