The summer's over! It's going to be lonely

An old classmate comes nearby at the summer training camp. The homeroom teacher that Aiko admired is also with me. Aiko is looking forward to the reopening. However, when I met him, I was informed that the blank space of less than six months was surprisingly large. On the other hand, Spank, who was enthusiastic about the whistle of birds, found a wounded seabird. And as a result of the generous care of Aiko and Spank, the seabird flew back to the group safely. And my old friends also left something in Aiko's heart and went back to Tokyo. Somehow lonely, somehow missing people, the end of summer...
