One Century to Marriage

Princess Marianne fell in love with an elf she saw at a tournament. Alas, Marianne is not free. She already has a fiance. The elf has entered into a duel with her fiance without warning of the law of the magical world, which can separate the lovers for a century if the rival dies. Marianne is kidnapped by ice dragons and taken to the castle beyond the clouds, where the queen of the fairies, also subject to the law of one century before marriage, is languishing in prison.
