Kinoshita Utage is a high school girl who is a fan of the rising idol group F/ACE, specially of the sexy and wild member of the group, Fukuhara Tamon. During her job as a part-time house cleaner, Utage substituted for a sick co-worker, and found herself at Tamon's house. It's like a dream come true! Except Tamon in real life wasn't quite what she expected from her idol.
