Utage Kinoshita is an excitable high school student who supports Tamon Fukuhara, a wildly popular member of the idol group F/ACE. To Utage, Tamon is a flawless, radiant idol who gives her the motivation to get through daily life. Utage works as a part-time housekeeper, and is assigned a new client when a coworker gets sick. To her surprise, this new client is Tamon, and she quickly discovers that behind his perfect public image, he is deeply insecure, pessimistic, gloomy, and has no friends. As Utage becomes involved in Tamon's private life, she works to support him through his self-doubt and fear of failing his fans, while struggling to reconcile the contrast between his idol persona and his true self.Characters
