In the last autumn of the student, I realized my wish with Nao who was a young child and started dating. I was aiming for the same university, but I failed. Nao decided to go to Tokyo first. "I write a letter!" I was encouraged by the letters sent regularly every season, and at the same time I felt that they were dyed into the city, so I felt complicated. On the other hand, Nao has a physical relationship with his seniors who met at university because of the momentum of drinking alcohol for the first time. The schoolgirls in the countryside, which was pure, were dyed into urban men's cock every time the season passed.
