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.

A serial killer targeted me. My sister-in-law was assaulted and murdered while trying to save me. Not only did I refuse to call the police, I pushed my father-in-law and mother-in-law down a flight of stairs when they came to help. I even helped the killer destroy the evidence. When my husband learned that his entire family got killed, he broke down in tears. He grabbed me by the collar and demanded, "Why? Why would you do this?" I deliberately waved photographs of his family's gruesome deaths in front of him and burst into laughter. "Why?" I sneered. "Because they deserved it." My parents begged me to cooperate so I wouldn't be sentenced to death. Instead, I publicly severed all ties with them. Meanwhile, the murderer who escaped justice struck again, claiming another victim. As public outrage reached its peak, I was selected for the Memory Extraction Program. Before the sentence was carried out, my husband asked me one final time, "The Memory Extraction System is still a prototype. You could die during the procedure. "Tell us the truth now, and there's still a chance to make things right." I slowly raised my head to look at him. "You're not getting a single word out of me." The crowd instantly erupted. People shouted that a worthless life like mine deserved to die. But when my memories were finally extracted, they were the ones crying and begging someone to save me.

A string of sexual assault cases sweeps through Fenborough, and all the evidence points toward me. In just a single night, I've become the prime suspect and target of everyone's anger. The moment I get home, my wife, Natalie Parker, glares at me with hatred and disgust. "A monster like you doesn't deserve to be called a human!" As she rages at me, she dumps a bottle of sulfuric acid on my crotch. The agonizing pain makes me collapse onto the floor, unable to move. The next day, she brings another man to the house—Harvey Green. He looks down at me and says, "So you're nothing but a scumbag. No wonder she detests you so much." Natalie also eyes me coldly, her words cutting as she says, "Why would I keep a tainted piece of trash like you around? Just the sight of you disgusts me." I refuse to believe that I would ever commit such a crime, so I secretly arrange for a DNA test—but the results prove that my DNA is a match with the culprit's. My blood runs cold. A wave of despair washes over me. Once Natalie sees the results, she brings the victims to the house. They charge at me, smashing glass bottles against my head and breaking my legs with bats. When my parents rush over and see this, they faint on the spot. I end up dying on the operating table. Suddenly, my eyes open again. I've been reborn. I've returned to the day the crimes took place.
