Mariko is an 80-year-old veteran writer, active in the magazine "Gunsei". Since she was always a writer and never a housewife, she could be described as "out of touch" in that regard. Her husband is deceased, and she leaves home after realizing her family sees her as a nuisance due to her age. However, despite being in her eighties, Mariko is quite energetic and in good health. 

The manga centers on veteran novelist Mariko Kōda, who lives with the families of both her son and her grandson in one house. Feeling like she no longer has any place in her home, she decides to leave the house and strike out on her own, beginning with living in a manga cafe in the city.
