Miki was responsible for holding down the fort at home while her husband worked away from home. Though lonely, she spent her days caring for her frail father-in-law, Osami. However, when her father's factory back home went bankrupt and loan sharks began hounding her, Miki found herself cornered every day, her voluptuous body subjected to abuse. Noticing a change in Miki's demeanor, Tatsumi hired a private caregiver to investigate her personal life. Once he learned the truth, his previously gentle attitude shifted dramatically, and he began aggressively pursuing her.
