The reason a health device became the emotional anchor in the life of 24-year-old Junko was deeply tied to a pivotal moment in her youth. As an elementary school student, Junko became intensely curious about the electric massager her father used every night. Witnessing him use it, she developed a pure desire to try it herself. But whenever she asked her father to borrow it, he refused—eventually going so far as to hide it from her. This only intensified her longing, leading her to secretly search his study during the day. On the fourth day, she finally got her hands on the coveted massager and nervously pressed it against her shoulder. Unexpectedly, she felt nothing but ticklishness, unable to experience the pleasure her father seemed to enjoy. In that moment, her dream shattered, and she threw the device aside. Yet it continued buzzing loudly. For the next ten minutes, she remained in a state of limbo, torn between despair and hope, saying a silent goodbye to the device. But she didn't give up. Experimenting with applying the vibrations to other parts of her body, she rediscovered its allure—moving from her chest and waist to her stomach, and eventually to her groin. Captivated by the sensation, she began relying on the massager as her emotional crutch. Rain or shine, on her first day of school, her birthday, when she fell for a boy, or during tough times—Junko continued to depend on the massager. It was no longer just a health device; it had become the pillar of her emotional world.
