After I transmigrate into a Gary Stu novel as the evil male supporting lead, a system appears in my mind. It tells me that as long as I can conquer one of the female leads, I will be able to return to my original world with a healthy body. But I've failed in my conquest. There are a few female leads in this novel. There's the fake heiress, Leslie Jackman, who I have grown up with and have viewed as my older sister. The true heiress, Miranda Suller, is a boxer who happens to be seatmates with me during our high school times. My childhood sweetheart, Catherine Langdon, who's also a genius surgeon, happens to be one of the female leads too. Heck, even my own daughter, Natalie Jackman… my own flesh and blood… All of them are quick to fall for Gabriel Linner, the poor yet strong-willed young man who's also known as the Gary Stu of this novel. Because of that, they hate me deeply. The system sighs before telling me that as long as I can die in the hands of any of the female leads, it will let me return to my original world. Later on, I use all of the tricks up my sleeve and succeed in getting killed by the female leads. But why is it that they've lost their minds after I die?

She was never supposed to matter. The novel never gave her a name worth remembering. After dying in a mundane accident, twenty-three-year-old Clara Quinn opens her eyes inside the pages of the fantasy novel she despised most — reborn not as the heroine, not as the villainess, but as an unnamed background character fated to die before the story even begins. Her plan is simple: stay invisible. Attend the Imperial Academy of Asterveil, avoid every named character, and quietly survive a plot designed to destroy everyone foolish enough to interfere. That plan lasts exactly one day. During the entrance ceremony, Lady Morwen Ashvale — the infamous crimson-eyed prodigy that even crown princes fear — steps off her platform, walks past every noble heir waiting for her acknowledgment, and stops directly in front of Clara. "You belong to me," Morwen says, loud enough for every student in the hall to hear. "Do not forget it this time." This time. Clara has never met this woman in her life. Yet Morwen looks at her as though she has been searching for centuries. As shadows begin stalking Clara through the academy's cursed corridors — as the original story fractures and rewrites itself around her — Clara uncovers the truth that should be impossible: Morwen has lived this story hundreds of times. She has watched Clara die in every single one. And in every timeline where Clara falls, Morwen burns the kingdom to ash. She is not obsessed. She is grieving. She has always been grieving. And this time, she refuses to lose again.

As the news broadcast reported a random serial killing near my residential complex, I knew—I had been reborn once again. In my first life, my husband insisted on going out in the middle of a snowstorm to buy weapons for self-defense. I locked every door and window, waiting at home, anxiety clawing at my chest. I never imagined the killer could pick locks. Before I could even react, a blade plunged into me, and I died on the couch. In my second life, I didn't hesitate. I hid in a concealed storage room, holding my breath. But the door was still pulled open. A man wearing a rabbit mask stared straight at me. "Found you," he said. In my third life, I ran to the police station. I rushed inside and told the officer on duty that the killings weren't random—that the murderer was coming for me. They looked at me like I'd lost my mind. Then my husband arrived in a hurry and took me away. But the moment we reached our front door, a heavy hammer smashed into the back of my head. Through the blinding pain, I forced my eyes open, but I never saw who killed me. Now, staring at the grave expression on the news anchor's face, agony surged through every inch of my body. Rebirth isn't a reset. The damage accumulates—and sooner or later, it will torture me to death. Without hesitation, I walked into the kitchen and set a pot of oil to heat. And I waited… for the moment the lock began to turn.
