The Kanda couple have been married for 40 years. The wife, Ruriko, is a full-time housewife, and the husband, Hiroshi, works as a county government employee, staying busy even so. Together, they raised two sons. Meanwhile, their eldest daughter had a child. It was their long-awaited first grandchild. Seizing this opportunity, Hiroshi quit his job, and the couple spent time together taking care of their grandson. In their spare time, they went on a long-overdue hot spring trip… After enjoying the hot springs for the first time in a while, the two reaffirmed their love that had lasted 40 years in the family bath.
