Raising the Unfortunate Favorite Character to be the Villainous Dragon Prince

Rika Kawashima died a tragic death because of school bullying. Just before she died, she regretted living a life where she was always pushed around. She promised herself that if she could live her life again, she would definitely fight back and make her bullies bleed, even a little, before she died. Suddenly, Rika woke up and found herself reborn as Lydia, a maid in the world of her favorite novel! Lydia becomes the personal maid to the Second Prince, Orlando, who's destined to be a tragic side character. And guess what? Orlando is Rika's absolute favorite character! Orlando was a secret child born between a dragon and the emperor. In the first half of his life, he was locked away in a tower, seen as "worthless." In the second part of the novel, the emperor used him as a tool to unite the continent, and he was even used by the main hero and heroine as a stepping stone, eventually dying a sad death. Rika saw her own life in his tragic story. So, she decides to raise him to become a "villain" who will stand up to the hero and heroine. She figured, if the world is this unfair, then she might as well just break the world itself! But there's a problem. The original Lydia in the novel used to bully Orlando. So, even though Rika is acting as Lydia, Orlando is just confused by her new behavior...
