Keiko and her husband, Satoshi, who lost their longtime wife and now visit their husband's parents' house where their father-in-law, Daisuke, lives alone for the first time in a long time. When I saw my father-in-law showing a bonsai to Keiko, who I hadn't seen in a long time, I was relieved to see him. Keiko finds out that the house Daisuke lives in is being targeted by landlords. Looking at Daisuke's profile, who laments that he doesn't want to lose the house full of memories, Keiko wants to help him in some way, and asks her husband if he should move in with his father-in-law.
