 The main part One 's story takes place at a Japanese high school , though little is shown except for Kōhei 's classroom , the cafeteria , and a little of the surrounding area . The main school building is three @-@ stories , and the roof is accessible , albeit with a sign on the roof 's access door saying " No Entry " , but the door is never locked regardless . Adjacent to the main building is another which houses club rooms . The school borders a forest on one side with a chain link fence . Beyond the forest is a park with a fountain and a flight of stairs on a hill . Other than the school , the shopping district in town and the usual path Kōhei takes to school are shown , but otherwise the only other place depicted is Kōhei 's two @-@ story house .
