At that point, his older brother, Leol, announces the annulment of his engagement to his fiancée, Charlotte. In order to protect Charlotte, who was falsely accused, Alfred daringly plays the villain and somehow succeeds in saving the young lady for the moment.

...Just when he thought it was over, lo and behold, Charlotte ends up becoming Alfred's fiancée.
