The idol group F/ACE has recently surged in popularity, largely due to Tamon Fukuhara, its handsome, wild, and talented leader. Seventeen-year-old Utage Kinoshita is a devoted fan who deeply admires F/ACE. Since her life centers on worshipping Tamon, Utage works for a housecleaning company to earn money and continue supporting him. When her coworker falls ill, Utage is assigned to a new client who shares Tamon's name. She assumes it is just a coincidence—until she encounters the actual celebrity! Her astonishment deepens when she learns that, contrary to the extroverted superstar the public knows, Tamon is actually a gloomy individual lacking friends and self-confidence. Because Utage's adoration for Tamon is boundless, she vows to keep his secret and remain by his side—though managing Tamon's contrasting behaviors inside and outside of work may prove to be the most difficult task of all.
