Oniisama e Episode 37 English Subbed Episode Title:Carousel.Episode Description:Kaoru tells Nanako that she broke up with Takehiko because of her illness and masectomy, and that Nanako is really Takehiko's stepsister. Nanako's father tells Nanako that she has a stepbrother, and that he loves his son as much as he loves her. Nanako is relieved and visits Takehiko. She asks him half-jokingly what he would have done if she'd fallen in love with him, and he is flabbergasted. Later that night, Kaoru rings Takehiko and apologizes for telling Nanako that Takehiko is her real brother before hanging up. Takehiko and Kaoru remember a date where they went to the fair and rode on a carousel. Takehiko goes to his father for a reference for his study in Germany, and his father wishes him well.
