Sunny autumn weather. A house in a certain mountain village. Yukari is cleaning while humming in a good mood. Suddenly, I stopped cleaning and took out a postcard from my apron pocket. A letter from her nephew, Daisuke, arrived a few days ago. Reunion with him since the funeral of my husband who passed away eight years ago. Reiko was looking forward to seeing her grown-up nephew again for the first time in a long time. However, Yukari's half-ass, which is too big, always sticks out unconsciously.
