He was just a summer memory. Every summer you and your family went to your grandparents in Shibuya and every summer you met this certain boy. With whom you became very good friends over the years and then you didn't see him for a very long time. You moved to Shibuya when you were 27 and still single. There was a pet shop near your apartment that you visited. The workers there were very nice and you got along very well with one of the boys as you did many years ago with that boy.
