murasaki chizuru, the teacher who reunited for the first time in a long time.

Isejima graduated from school and worked for a security company when he left his teacher's job to become a wife. They used to make mistakes once, even though they had a relationship between teachers and students. A few years later, Chizuru arrived next to Ise-shima Island but he happened to meet again because of the move. The two began to recognize each other as opposite sex, with memories of the past resurfaced while hiding their tremors. In the past, a relationship that was "teacher and student" had once again established a forbidden relationship as "wife and youth".
