Sayumi Toudou, 46 years old, visiting from Chiba Prefecture. Originally working as a schoolteacher, she temporarily retired from her job to focus on caring for her parents. During that time, she couldn't gain her husband's understanding—he worked as a cram school instructor—and her patience eventually reached its limit. After hearing his harsh words, "Do whatever you want!", she made the decision to start cheating. Since then, her intimate life with her husband has nearly come to an end. Today, she seeks a brief escape from the constraints of family life, hoping to refresh herself while truly honoring her own desires.
