Why am I the only one who dislikes her?

The fiancée of the Crown Prince, a Duke's daughter, held feelings of disgust toward a Count's daughter whom she met upon entering the academy. She attempts to admonish the Count's daughter for her unbecoming conduct, but those around them take the Count's daughter's side instead, and the Duke's daughter is ostracized as the villain. As a result—— I plan to regularly post short stories in order to improve my writing skills. It would greatly encourage the author, so I would be very grateful if those who read this would please leave ratings and bookmarks.
