"I Was Reborn as a Villainous Young Lady, But I Won't Interfere with the Heroine Until the Main Story Ends - Short Story"

When I was twelve years old, I learned that I was the villainous daughter in a game, destined to have my engagement broken off at a graduation party and be sent to a convent. From that point on, I lived carefully, making sure not to displease the crown prince, my fiancé, and not to bully the game's heroine. But in the end, the conclusion didn't change—I was dumped just as the game's scenario dictated... Hehe, everything is going according to plan. The crown prince and the baron's daughter should enjoy their time in the sun while they still can. From now on, they will dance to my script.
