Three years after marrying her husband, Karen had one worry. Her husband's uncle, Shigefumi, started living with them. Her husband regards his uncle as his benefactor and lets him live with them, but Karen feels uncomfortable around him because he doesn't look for work and treats her with naked sexual desire. Then, her husband is transferred to a rural area, and she ends up living alone with her uncle for half a year. Her uncle, not wanting to miss this opportunity, approaches Karen after her husband leaves home, rummaging through Karen 's room and finding some revealing photos from her past part-time job.
