Years into her marriage and troubled by her relationship with her husband, Yuna attends a long-awaited reunion and meets Ozawa, the teacher she once admired during her adult-student days. They exchange contact details, and she begins confiding in him about her marriage. One day she sees her husband happily walking with his lover and calls Ozawa in despair. He gently holds her and, despite his guilt, kisses her. Yuna responds by wrapping her legs around him and pressing her sweaty body tightly against his.
