The Marriage of the Aging Duke and the Fallen Noblewoman

Once upon a time, there was a duke known as the "Lecherous Worn-Out Duke." Young ladies who married him would mysteriously lose their lives after just a few months, and he would take another young wife. No matter how terrible the rumors spread throughout the kingdom, no one dared to defy the duke, who was the brother of the king. This is the story of a fallen noblewoman who becomes his twenty-third bride. ※This work is also published on Kakuyomu, pixiv, and Tales.
