Haine has been in love with Shizumasa Togu from the day she read the picture book he wrote as a child. She enrolls the Imperial Academy to be close to him and is accepted as a member of the student council. But with that, dark secrets start to reveal themselves! Why does "The Emperor" act differently? Is Haine really in love with Shizumasa? Why did her father sell her and why doesn't her mother write to her anymore?
