Help! I don't want to be the female lead

When Park Seraphine suddenly discovered that she had been transported into a book as the main female character she despised, she was utterly stunned. The real issue wasn't just being the Female Lead; it was the fact that every man in her life seemed to embody sadistic tendencies - her three brothers, the crown prince, her loyal knight, and even the mage. Though she initially accepted the role, Park Seraphine decided she wouldn't tolerate their cruel behavior. Determined to stand up for herself, she vowed to resist these sadists and fight for her rights, no matter the cost. As for the idea of a romantic happily-ever-after with the Crown Prince, she dismissed it right away. Her desire now was to have the power over him, ensuring a different outcome for her story.
