His parents have passed away, and his older brother and his wife Ayumi live at home. I used to come here often, but due to a certain event, I moved away from my parents' house. I betrayed my brother, even though it was a drinking party. One day, Typhoon No. 19 hit directly. I was hit by a torrential downpour and went to my parents' house to take shelter from the rain. However, that night the train stopped and my brother couldn't go home from work, so he was alone with Ayumi, who was soaked in no bra on the way home from shopping.
