A woman living in Kyoto confesses via email. After four years of marriage, sex with her husband has become dull and routine, and she no longer initiates intimacy. Filled with loneliness, her masturbation fantasies have grown increasingly intense. She has begun harboring bold desires—such as being tied up and taken by a stranger. In her email, she openly admits feelings she could never act on alone, expressing a strong longing to engage in perverted acts. She desperately pleads for someone to train her and turn her into a true perverted woman.
