Manarina, a full-time housewife, used to work as a teacher before getting married. One day, she reunited with Seto, a former student. Seto had lost her job and was feeling discouraged. Manarina comforts and encourages such a student. However, contrary to her kindness, Seto's dark passion begins to erupt. The female teacher Manarina, who had severed her feelings, suddenly reappears before her. In broad daylight, Seto steals away from her husband's eyes and pours out her feelings to the married woman Manarina and forces herself on her. Manarina, who resists fiercely, is nevertheless subdued by Seto's roughness.
