This is a story about a teenage girl, Hiroyuki, with a serious problem-everyone thinks she's a boy! She's tall and skinny, with no figure, and has a very masculine face(for shoujo 😛 ) She really likes a teen idol called Kazuki. When she sees a notice for an audition to be in a commerical with him, she decides to try out, but it goes disastrously. Though she wears a long wig and a dress to try to look feminine, it backfires. After the audition, she runs into one of the interviewers, who says that though that audition didn't work out, Tsuchino(the agent) likes her look and thinks she would be very popular with teenage girls. Of course, hearing it like this, Horiyuki refuses, until she sees one of Tsuchino's other clients-Kazuki! Tsuchino says Kazuki needs a friend, since his schedule doesn't permit normal relationships, and Hiroyuki agrees. So Horiyuki is introduced as a boy to Kazuki.
