Plot
Haine Otomiya, a 15-year-old high school student at the elite private Imperial Academy (帝国学園 Teikoku Gakuen), was apparently sold to the Otomiya family by her father, Kazuhito Kamiya, for 50 million yen. Disoriented with her place in life, she became a gang member until she met Shizumasa Tōgū, who told her to live life how she wanted to. Recognizing Shizumasa as the author of a treasured picture book given to her from father, Haine reformed herself and entered the Imperial Academy to try and win his love.

However, Shizumasa is the Emperor of the school, the sole Gold rank student as the admired President of the Student Council. Through various circumstances, the Bronze-ranked Haine is tricked into becoming Shizumasa's bodyguard and assigned the special rank of Platinum - which designates her as the Koutei's companion. To Haine's surprise and disappointment, Shizumasa claims not to know her and acts coldly toward her. Still determined to win his love, she soon learns that the Koutei is not Shizumasa, but his twin brother Takanari. In the brothers' childhood, Shizumasa won the right to be recognized as the heir to the prestigious Tōgū family, which left Takanari to become his brother's "shadow" and was reported to have died. Because Shizumasa is sickly, Takanari is forced to assume Shizumasa's identity and reluctantly falls in love with Haine. Their relationship is strained by Haine's uncertainty as to whether she loves Shizumasa, whose kind words saved her during her darkest crisis of identity, or Takanari, who is revealed to be the author of her beloved story book. In the end, she decides to marry Takanari.
