Raika, who loves helping people, and Atori, who adores musicals, are childhood friends. Since they were little, the two of them would put on plays just for each other, with no audience. Raika always thought that Atori's acting was impressive. Raika thought that if Atori loved it so much, she should join the drama club. But Atori wouldn't hear of it, saying, “Raika isn't in the drama club,” and “It's enough that Raika watches me.” Then, due to certain circumstances, Atori ends up taking the stage.
