Diary of Beloved Wife: Naive

Yoko is an ordinary housewife living in an ordinary apartment block. Leading a comfortable, if predictable, life with salaryman husband, Shinichi and their 11 year old son, Junichi, she has no real complaints as she goes about her tedious days, but feels increasingly at a loss regarding Junichi's recently-acquired adolescent independence. As Junichi takes off for cram school camp, Yoko and Shinichi are faced with the prospect of spending time alone together without their son. How will this couple, who’ve already lived half of their lives, change their behavior when it’s just the two of them? Can they recapture the spark of wedded bliss?
