Living together with her son and his wife led to marital troubles. The daughter-in-law was always on edge, and the son was forcing himself to cope. One day, the daughter-in-law suddenly exploded in anger and stormed out. The son, burdened with endless worries, was left in despair—until Chisato Shoda appeared by chance. Seeing her, the daughter-in-law abruptly left. Chisato gently comforted the son, pulled him into a warm embrace, and said, "I'll handle everything around the house." A few days later, the son submitted divorce papers to his wife and began a new life with Chisato. Arriving at their new home, they started unpacking the cardboard boxes when the son kissed Chisato, marking the beginning of a passionate new relationship.
