Married for three years, she secretly works nights as an escort to support her ill husband and repay their debts. Giving her body to strangers feels like a betrayal, but she refuses to surrender her heart and tells herself it will end once the debt is cleared. Just as repayment comes within reach, she arrives at a hotel booking and finds Imai, the teacher who sexually harassed her during her adult student days. From that day on, he forces her to become his obedient sexual outlet.
