Rei is a married woman who teaches at the same school as her husband. One day, her husband reports that Machida, a student in Rei's class, seems to be in low spirits. The next day, her husband witnesses a student, Yamaguchi, bullying Machida. Yamaguchi is injured when Rei vigorously defends Machida. After school, Rei also calls Yamaguchi and Machida to find out what happened, but Yamaguchi threatens to tell the school board about her injuries. Yamaguchi then orders her to show her breasts if she doesn't like it...
