Aoba Private Academy is located on a slightly elevated hill surrounded by a quiet residential area lined with mansions. It is a private school with a prestigious reputation where many daughters and sons of good families attend.
The school's culture is based on the school motto, “Friendship, Diligence, and Innocence,” and the school's long-established school rules are highly respected.
Fusae Fujishima, a graduate of this school, was assigned as a Japanese language teacher a few years ago. She is serious and strict, and was in charge of the life guidance advisor. She was considered a hard-headed and inflexible teacher, and was looked down upon by the students.
--One day after school--
After homeroom was over, Fusae was patrolling an empty hallway as usual, Fusae discovers a female student sneaking around and acting suspiciously.
Fusae followed her, and what she saw was...
It was an image of her husband, Yoshio, and his student, Yoshimi, locking lips in an empty, somewhat dimly lit classroom. She has been married for three years to Yoshio, a teacher at the same school.
Fusae thought things were going well with her husband, even though they were not even having a physical intimate.
From then on... Fusae started to change little by little...
With the collapse of morals, a short ADV depicting a female teacher who is mad with jealousy and indulgent in pleasure.
