In A Couple's Duet of Love & Lust, a young married couple moves into a new neighborhood after selling their home after an unexpected financial crisis. You can play as both the husband and the wife in this game. You must direct them to get their lives back in order. It isn't going to be easy since there are no clear-cut paths to success. You must do what's right for each of them, and sometimes that means making decisions that might not be the best for the husband or the wife. NTR or any non-conventional relationships are avoidable.
