The three couples with "happy endings" ruin this drama for me. The acting and the dialogs were excellent until the last episode. The happy ending cheapens the main theme of the show about love and marriage. In real life, not all couples end up in love and marriages. I would have given the series a 10 out 10 if not for the last episode. The interactions between the mother in-laws and the daughter in-laws are accurately depicted as the one of the issues in the marriage, especially in the Asian society.
