Married for six years, Saki works as a home caregiver alongside her husband. Gentle and kind, she works tirelessly every day to support the family financially. One day, she goes to the home of a new patient. The house is occupied only by an elderly man, as his son lives far away. This man, a former real estate agent who made a fortune during the bubble economy, has been abandoned by banks and now only has savings. He recounts his past to Saki, stating that if he were to die, he wishes to leave his estate to his wife. "I will leave my estate to my wife, what about you?" "I will keep making love to you until I die, Dad," the elderly caregiver, deceived by the man, is tempted by his mature body.
