I seem to be a villainess even with something like this.

A duke's daughter with memories of her past life is exiled from the country after being accused of harassing her fiancé prince's mistress. The former duke's daughter has no memory of committing any harassment. In the first place, she despises the arrogant prince so much that she would gladly hand over his mistress to him. Besides, even if she had harassed her, isn't it the fault of the mistress and the prince for committing adultery in the first place? However, her innocence cannot be proven, and unreasonably stripped of her status and the country where she was born and raised, the duke's daughter is exiled with nothing but the clothes on her back. Two years after her exile, the former duke's daughter who had lost everything. A knight arrives from the country that exiled her. It seems he has some kind of request.
