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.

I quit and dipped. City threw a parade. Only Jenna Blake—my oh-so-gifted junior who claimed she could "see through killers' eyes"—lost it. At her celebration banquet, she went full drama queen: "I owe everything to Kate Mercer. Please, bring her back!" I laughed. Cold. Not happening. Last time around, I was the hotshot detective. But every clue I found? She dropped it first like she read my mind. People started saying I was washed. So I went all in—three months, no sleep, cracked a massive trafficking ring. Led the raid myself. She beat me there. Again. Place was cleaned out. Boom. She's the city's golden girl. I'm the clown with no game. Pressure got ugly. My head snapped. I died chasing the last scumbag. Then—bam. I woke up. Same day. Raid morning. Round two.
