A 32-year-old Naoko Noda has worked in the corporate strategy division for 10 years. She has a nickname, "anego" ("older sister"), given by her younger co-workers, whom she gives guidance and advice.
Based on Mariko Hayashi's novel of the same name, Anego realistically portrays Naoko's everyday life; her love life, the problems she faces, and the uneasiness she feels about the future.
