Three years into her marriage, housewife Miho has been struggling with persistent shoulder and lower back pain that just won't go away. On her husband's recommendation, she decides to try a newly opened mobile massage service located near the station. That weekend, a male massage therapist arrives at her home and carefully works on her shoulders and lower back. The treatment proves even more effective than expected, leaving Miho thoroughly satisfied. With her husband's permission, she begins scheduling repeat sessions the following week.
