Read manga: Normal High School Girls Tried Being Local Idols

manga
Summary:

High school girl Nanako became her town's local idol at the request of her uncle. She and her upperclassman Yukari, a girl who seems perfect but ends up being airheaded, both become idols of their provincial area. They get interviewed (by the town's shopping center), go on television (low-budget cable), and hold concerts (on the roof of the department store). The girls' salaries come from the town's taxes.
