Prior to his marriage, the investigator Maki was retiring but still a housewife and kept the area safe as a special secret agent. One day, Umeda, who was a childhood dyer when he was a child of Maki, happened to move to his neighbor's house. After a long reunion, they have had an exchange and the two of them will have a relationship. At the same time, there were many vacant nesting incidents in the neighborhood. When I received a request and proceeded with the investigation, the culprit who emerged on the line of investigation was Umeda who felt in love.
