Overview
Utage Kinoshita is a high-school student and housekeeper whose devotion to idol Tamon Fukuhara knows no bounds. She is his biggest fan, following his career with total dedication. But when she gets closer to the idol himself, she discovers a very different Tamon behind the stage persona: gloomy, withdrawn and nothing like the shining star she admired from afar.
Based on a manga, this 13-episode comedy plays with the gap between idol image and real life, as Utage tries to reconcile the Tamon she loves on stage with the Tamon she meets off it. It is a warm, funny look at fandom, first impressions and the surprising sides people keep hidden.
