The question of whether love is fated or love is driven by circumstances is realistically portrayed in this drama. What I love is the step by step decision making that goes into the separation and the divorce and the natural attraction of the leads. This wasn't a lust drama but one of mutual respect for the person that is the object of affection. One of the most satisfying endings for a K drama that usually spoils the ending withe the contrite attempts to redeem characters so everyone has a feel good experience. In real life and in this drama responsibility is the main theme. Responsibility to marriage, children and to self are all analyzed in unique ways. Tolerance and intolerance are so explored. Worth watching again and I thank the writers for seeing this drama through to a mature adult ending not some make believe fairy tale ending.
