Otto to Kaiwa ni Nari Masen

Ayako, a housewife, lives happily with her husband Yusuke, who works at a design firm, and their 4-year-old son. She has been married for six years and has no complaints about her husband, who is active in housework and childcare while also managing his work. However.. what has been bothering her a little lately is the fact that she and her husband don't talk much. "When our son was a newborn, we used to talk a lot as a couple. When did our relationship become like this? I want to know why, but I can't seem to talk to my husband today."
