Imperial Academy is an elite private school whose student body is divided into the ranks of Gold, Silver, and Bronze. Depending on your family's wealth and your individual merit, you can be classified as a Silver or Bronze student. However, there is only one Gold student, and this year that person is Shizumasa Touguu—nicknamed "the Emperor" because he is the Student Council President. When she was very young, Haine Otomiya fell in love with Shizumasa, after reading the children's picture book that he authored. She had met him twice before attending Imperial Academy, but as a Bronze student, her rank is far below his, so she has been unable to approach him at school. Haine jumps at an opportunity to get close to Shizumasa, and she unexpectedly becomes his bodyguard as well as a member of the Student Council. It seems like a dream come true for her, but soon she will learn that everyone in the Student Council is hiding secrets, and her own shameful history cannot be forgotten either.
