Yuka has made a mistake that should not be attributed to a well-behaved teacher. I had a physical relationship with her student Kobayashi. If you get caught, it's the end of the first volume. Yuka, who had such a bomb, carefully continued her relationship with Kobayashi. Adolescent Kobayashi was so absorbed in Yuka that he could only think about sex. With the wind that blows her worries about Yuka, she finally ends up asking for a body in her school. Yuka, who was completely confused by the situation where she could be exposed to anyone, became obedient to pleasure.
