The autumn sky is clear and bright over a quiet mountain village. On this pleasant, sunny fall day, Reiko is cheerfully humming to herself as she cleans her house. Suddenly, she pauses her work and pulls a letter from her apron pocket. It's a letter she received a few days ago from her nephew, Daisuke. They haven't seen each other since her husband's funeral eight years ago, and now he's coming to visit. Reiko eagerly looks forward to seeing him again. Her heart flutters with excitement, filled with joy at their long-awaited reunion.
