Nao, a young wife student who gives birth immediately after marriage and attends college while raising children. Nao is a tutor for Yoshioka, an examinee who lives next door to the same apartment as Nao, through an introduction from her university. She has a serious and bright personality, and Nao is weak to push and can't refuse. At times, Yoshioka tries to gain sympathy for Nao, and at other times tries to use her exams to give her his virginity! Nao, who has a husband and a child, desperately resists, but after giving birth, her body, which is her frustration, gradually overwhelms the momentum of young students.
