My parents died, and my brother and wife Ayumi live in the family. I used to come here a lot, but after an incident, I was away from home. I betrayed my brother, even though he was a drinker. One day, the typhoon was hitting directly. I went to my parents' house because of the heavy rain. However, the train stopped that night and my brother couldn't go back from the company, so he became alone with Ayumi of Nobra who was drenched on his way home from shopping.
