One night, she bumps into a student who hasn't been coming to school recently. When she asks him about the situation, he tells her that things aren't going well with his parents. Perhaps it was out of parental love, but Ayane invites the student into her home and makes her first mistake... Then, using this as an excuse, a fellow teacher pressures her into a relationship, and gradually she breaks down. The student leaves, and in her despair, she finds a new life in her belly... Ayane, who has lived a diligent life as a teacher, is toyed with and corrupted by many men... A full-scale drama from Kinema-za!
