The local school in the Uwakoi manga is a central setting since the main characters are teenagers.
Events are shown in a variety of places, primarily in the same classroom attended by Yukiteru and Yuno (and later Rena, Kaori and Alice), also corridors and stairs, the sports courts and swimming pool, changing rooms, and the sports storage basement.
In the early part of the story, Yukiteru and Rena have sex in the girls changing rooms. Yuno uses the land sports facilities there (athletics club), and Rena uses the swimming pool (swimming club). Later, in the corridor Yuno knocks Yukiteru unconscious, then beats and rapes him in the emptied swimming pool.
