Gimai ni Oshitsukerareta Totsugisaki wa, Norowareta Koushaku Kakka deshita

Miltia was treated as a servant and oppressed by her stepmother and her stepsister because there was no blood relation between her and them. She was having trouble getting enough food to survive everyday. Somehow she was able to get by through cooking whatever thing she could find herself. In the midst of all this, her stepsister, who was doted on by both her stepfather and her stepmother, along with her fiancé, who was only interested in a woman’s youth and physical appearance, cruelly broke off her engagement in public and forced her to marry the notorious "Cursed Duke," the Duke of Lönnrot.
