I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story. His character setting was the one man the soft, delicate heroine could never win over. He was the cold, unattainable Prince Charming she could never conquer. When the heroine cried and confessed her love, he was studying. When she offered him her whole heart and body, he was busy starting a company. When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.

After transmigrating into a novel, I realized the heroine and I had the exact same name. Naturally, I thought I had transmigrated into the female lead. So I marched straight to the man who was still a broke nobody at the time, threw all caution to the wind, and pounced on him like I had plot armor protecting me. He even glared at me with red eyes and told me he hated me. I honestly thought he was just into the whole push-and-pull thing. Everything shattered when the real heroine showed up and I finally understood one thing. He actually hated me. Heartbroken, I packed my bags and got ready to disappear. The next second, he pinned me against the wall. "Where are you going? Already bored of me, sweetheart?"

When Park Seraphine realizes that she had transmigrated to be a character in the novel, she was shocked. On top of that, she was the Female Lead whose life she despised. Even though the Female Lead wasn't her favorite character, that wasn't where the problem lied! It was the fact that all the men around her was sadists— her three brothers, the crown prince, her knight, and the mage! Although the Female Lead bore with them, Park Seraphine wasn't willing to do the same. She was ready to fight against those sadists for her rights no matter what it took! As for having a happy ending with the Crown Prince at the end, she discarded that thought from the beginning. What she wanted was that Crown Prince was to be at her mercy!
