Tamon's B-Side

Utage Kinoshita is a high school girl who works part-time as a housekeeper. She has devoted her life to her favorite idol, Tamon Fukuhara, from the group F/ACE. Then one day, Utage ends up being assigned to Tamon’s house! There she discovers that off-stage, he is nothing like his wild idol persona. A gloomy, introverted boy with no self-confidence, Utage still finds herself falling for him anyway.
