I came to a hot spring with my wife Natsuko and my younger brother Koji to celebrate my father's 60th birthday. He was blessed by his family and his father seemed very happy, and Koji was filming the situation from beginning to end. After dinner, everyone had a drink, but Natsuko, who was weak to begin with, fell asleep first. Then Koji also unusually drank too much and headed to the futon. At that time, I didn't know that something had happened in that futon that made me despair.
