Marie Antoinette married the Dauphin to seal the alliance between his grandfather Louis XV and her mother, Empress Maria Theresa of Austria, when she was 14. After her marriage, she realizes that Madame du Barry, King Louis XV's mistress, is against her. The princess, horrified by what she had heard about du Barry, decides to never speak to her. Meanwhile, she meets Count von Fersen, who becomes her lover.

Madame du Barry, always plotting against Marie Antoinette and Oscar, fulfils her desire to be greeted by her. After the death of Louis XV, Madame du Barry is condemned to die.

Marie Antoinette, after several conflicts with her husband, starts feeling lonely. Fersen, who had left France on Oscar's advice, returns. Rumors swirl about the Queen and the Count, and Fersen leaves again. A depressed Marie Antoinette befriends the Duchess de Polignac. Polignac leads Marie Antoinette to her downfall.

Marie Antoinette is described as a "lively, silly girl of shoujo manga."
