Seventeen-year-old Utage Kinoshita lives and breathes for her favorite idol group, F/ACE—but the group's center, Tamon Fukuhara, occupies a special place in her heart. Every waking moment Utage dedicates to the thoughts of the wild and sexy Tamon, even taking on a part-time housecleaning job just to afford her fangirl lifestyle. What was supposed to be an ordinary job turns out to be anything but when Utage realizes she is cleaning the apartment of the very idol she so fervently admires! But adding to the surprise, Tamon is nothing like his on-stage persona; he suffers from severe anxiety and painfully low self-esteem. Keenly aware of the gap between their worlds, Utage cannot bear to see Tamon so depressed and decides to support him the best she can as his housekeeper. As time passes, Utage becomes more and more privy to the aspects of Tamon's life he reveals to nobody else. And the bond that forms between them soon leaves Utage wondering if she has accidentally crossed the sacred line between fan and idol.
