Yongjianyou (voiced by Hatakenakayou) is a first-year high school boy. He loves literature and is determined to become a light novel writer. He often submits his works to participate in some light novel writing competitions, but he is always passed in the first round. Yongjian has a sister named Lianghua (voiced by Kondo Rena). Lianghua has a beautiful appearance and excellent grades. She serves as the president of the student union in school and is the object of admiration of her classmates. At home, Lianghua naturally has no good face for her useless brother and always treats him coldly. By chance, Yongjian learned a piece of news that hit him hard. The novel written by his sister Lianghua actually won the light novel competition. The content of the novel describes a pair of very loving brothers and sisters, which is very different from reality. It turns out that in Lianghua's heart, she actually longs to be close to her brother.
