Even you won’t say no to me." Lucas: "Killing isn’t the thrill—it’s the build-up, the precision, the art in it. How can’t you see that?"

Blake, the obsessive stalker, Demitri, the commanding mafia Don, and Lucas, the twisted killer, each agree to let her into their lives—but none of them plan to let her go. Now, the author finds herself not just writing a dark romance, but living it, as all three men decide they want her for themselves.

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.

In real life, I had been pushed to the brink by an online romance scam. Just when everything fell apart, I awakened something called the Devotion System, and before I could make sense of it, I found myself thrown into a horror game. Among all the players, I was the weakest, barely able to take care of myself. If I wanted to survive, I had only one option—find someone stronger and cling to them, no matter what it took. However, things did not go the way I expected. Every player avoided me like the plague. Not a single one was willing to team up. With nowhere left to turn, I made a desperate decision. I chose a ghost. I treated her as my bound partner and devoted myself completely to her, clinging to her as if my life depended on it. However, as I spent more time with her, I began to realize she was not just something terrifying. She was someone who had been hurt, someone deeply broken. Hence, I stopped pretending. I began to help her sincerely. In the end, we overcame everything together and cleared the game. However, when I returned to the real world, I discovered something I never could have expected. She had followed me back. From that moment on, all I could do was wait for the system to pull me into the next stage.

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.

I was a housewife with severe OCD and a serious cleanliness obsession. I accidentally entered what I thought was a wholesome parenting game where I beat the crap out of my rebellious son, smothered my adorable daughter with love, and ripped out the corpse-stitching on my husband to sew him back up. On the day I cleared the game, the three of them tearfully sent me off. Only during the final settlement did I learn the truth: my husband was the ultimate boss of the horror game. My son was an infamous demon who left no players alive, and my daughter had crushed the skulls of a hundred players. Wasn't this supposed to be a parenting game? Turns out, I had walked straight into a horror game.
