Rin was indulging in an unseemly act for a teacher, having a physical relationship with her student. Touching the sexuality of a young man was stimulating, and secretly repeated meetings were transgressive. But the situation changed when her student sought a relationship even within the school grounds. Despite desperately trying to calm him down, the student, who had been trained by Rin and turned into a sex monster, wouldn't stop. Rin was thrust by her student in a corner of the school and could only desperately suppress her voice from leaking out.
