During the Obon holidays, I decided to go to my fiance's parents' house. I had heard about it, but it was in the middle of nowhere with no convenience stores nearby. The only person to greet me was her older sister, Saiharu. Apparently her parents had misunderstood the date and gone on a trip. I was a little disappointed, but... I didn't care about that anymore. My head was filled with thoughts of Saiharu.
