Minamoto-kun has a face pretty enough to make people think he’s a girl, which caused him to be bullied in middle school. Because of this, he developed a fear of women and went to an all boys high school. When he enters college, he makes a promise to himself to overcome his past. But then his father remarries, and basically forces him out of the house. However, he does make arrangements for Minamoto to live with his aunt. She is an extremely beautiful woman, and also a professor at his college. She is fascinated with the Tale of Genji, and decides to make Minamoto a guinea pig in her reverse Genji project.
