Wife Saori lived with her husband and father-in-law, enjoying an ordinary yet warm family life. One day, they left the house to see off her brother-in-law. Since her husband was drunk, Saori took the wheel for the first time. Nervous from the rare drive, her hands trembled as she drove. Tragically, she caused a severe accident. Her brother-in-law suffered serious fractures, while her husband lost his life—an irreversible disaster. Overwhelmed by guilt, Saori was crushed by remorse, losing all meaning in life. She began to feed on her own suffering, descending into torment and self-punishment.
