I've developed a fever all of a sudden. But that's when I hear the thoughts belonging to my Alpha mate, Alder Garrison, whom I've bonded to for five years. His voice is husky and attractive, and yet the tone he adapts is very unfamiliar to me. [She's pulling the pity card again. How annoying.] My breath hitches in my chest as I look up at Alder. He's in the middle of pouring me a glass of water, his gaze seemingly gentle beneath the light. His lips aren't moving at all, and yet I'm very sure that I heard his voice just now. When Alder helps me to sit up so that he can feed me the medicine, I purse my lips together before speaking up, albeit hesitantly. "Alpha Alder, I think I'm hearing things all of a sudden. Can you please accompany me to a healer's station tomorrow?" Alder is quick to envelope me into a hug and comfort me. "Shh… I'm here. You'll be fine." But his thoughts sing an entirely different tune. [Ugh… She's doing it again. Can she stop pestering me already?] I no longer utter another word. All I feel is my heart slowly going cold in despair.

[YOU HAVE TRANSMIGRATED INTO A VILLAINESS FATED TO DIE.] I was supposed to obsess over the Alpha King, scheme against the heroine, and meet my end at the execution block. Instead, I rewrote the story. I chose Pierre Ashbourne—the neglected second male lead I once pitied as a reader—and spent three years helping him rebuild his dying pack, believing I had finally changed my fate. Then he abandoned me at our mating ceremony for his first love, the heroine. Now, the system has given me only one way home, restore the original ending by pushing the heroine back into the arms of the ruthless Alpha King, Hades. But the more I try to complete the story, the more these leads are getting out of character! What should I do?

"I love you, I really really do~ please marry me" I closed my eyes in fear as I kneeled in front of the devil itself who had his hands warped around the female lead. The next thing I knew I stood in the wedding hall wearing the white suit while in front of the Villain itself putting the ring on my finger. "Now I declare you as husband and hu-husband? you may kill your husband" It was supposed to be a straight Otome game where I was supposed to be dead while saving the FL. But here and I married to the villain itself. "WHEN DID IT TURN INTO BL?" I don't own the cover as I just did the editing of the art and credit goes to its owner

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?"
