Yuka Sakuragi is turning sixty this year. Her husband passed away ten years ago, and she currently lives with her son, his wife, and their two grandchildren—a family of five. After her husband's death, she maintained a close romantic relationship with her former boss from her part-time job, enjoying loving and passionate days together. However, that relationship ended when he was transferred. Nowadays, she copes with loneliness through masturbation one or two times a week. Though she feels isolated at times, she continues living a peaceful life grounded in strong family bonds.
