You are The Villainess

You were living an ordinary life, until one day you woke up in the body of the Duke's Evil Daughter from a novel you read online. The Duke's Evil Daughter is a crazy character who did foolish things that led to her being isolated in an outlying palace. The Duke hates her. Despite being his only daughter with his blood, the original heroine is the villain's sister and the Duke's current stepdaughter, a beloved and pampered child. You have now awakened in the secluded palace where only a maid comes every two days. You don't remember the names very well and you don't know what they really look like because it was just a novel and you often forget names, but you remember most of the main and important events, not in detail, and you don't know exactly when they will happen. You will pretend to have amnesia regarding names, appearances, and some other things.
