Daiki was seriously injured in an accident caused by distracted driving. His wife Mio, who cared for him daily, faced immense physical and emotional strain. A few days later, Sato, the driver held responsible for the crash, suddenly visited the couple's home. Blaming the accident on them, he raged that he'd lost his license and been fired from his job—then proceeded to rape Mio right in front of Daiki. This incident became a devastating event that shattered the family's bonds and altered their fates forever.
