I transmigrated into a dating-sim otome game where I was supposed to romance a soft, fragile male lead. I had finally pushed him onto the bed and was just about to make my move when the long-missing system finally popped back online. [Host, I sent you to the wrong game. This is a horror game.] [The man you’re bullying right now is the horror game final boss.] I lifted my head and met a pair of blood-red eyes staring straight at me. My smile froze. “Um… you look a little tired. Maybe we should… continue this another day?” He smiled back, calm and terrifying. “I’m not tired. Go on.”

The day I was supposed to win the biggest award of my career, I walked in on my boyfriend, Ethan, in bed with another woman. He sneered, calling me a face-blind, scent-deaf bore in bed. I planned to expose his ass at the award ceremony. Instead, he and his lover mowed me down with their car. Next thing I knew, I woke up with them in an S-class horror survival game. Mortality rate: over 95%. We had to survive ten days in a haunted manor to be revived. Hit 100 on your Anxiety Level, and your soul is obliterated. Chloe, Ethan's lover, sneered. "Sensory defects? You can't recognize ghosts or smell danger. In a horror game, that’s a death sentence. You might as well just die." The others heard her and scrambled to team up. Me? I walked straight into the lair of the manor's final boss. The most powerful demon in the game wanted to devour my soul. I couldn't really see him. I just thought he was a cosplayer. I lunged forward, poked his abs, and pointed at the glowing crack in his chest. "Wow, you're really committed to the role. This getup must've cost a fortune."

My mom is one of the world's leading AI scientists. Not long after I'm born, she creates an AI companion sister, Nova, designed just for me. She claims Nova is equipped with the world's most accurate lie-detection system. If I ever lie, Nova can surely detect it. From that day on, Nova becomes the judge of my fate. Whenever she issues an alert and declares that I'm lying, it doesn't matter if I'm telling the truth—the only things waiting for me are a hard slap and a trip to the dark isolation closet. I try to defend myself and fight back, but Mom coldly insists that the AI robot she personally built can never go wrong, which only convinces her that I'm a habitual liar. On Children's Day, Mom does something she's never done before. She takes Nova and me on a trip to the amusement park. Looking up at the towering bungee platform, I clutch my chest and desperately shake my head. But Nova coldly pulls up her analysis report. "Tina's abnormal heart rate is from lying. A full-body scan shows that she's in perfect physical health." Mom's expression immediately darkens. She grabs me by the ear and drags me toward the platform. "How dare you lie again? You must jump today!" The moment weightlessness hits, my heart feels like it's exploded. The pain is so intense that I can barely breathe. As my vision blurs, Mom continues her lecture about my terrible lying habit in a disappointed voice. Bloody tears slip from the corners of my eyes. "This time, I'm really not lying, Mom. I'm dead, and I will never lie again."

I'm the fake heiress of a wealthy family. The system has given me three conquest targets to choose. As long as the affection score belonging to any of them becomes full, I can change my predestined death at the age of 23. But I've completely failed in my mission. The conquest targets have fallen for the true heiress, Evelyn Swanson, who has reunited with the family at the age of 18. As long as Evelyn says something, they can easily aim their malice and hatred at me. That's why I choose to take my own life in advance. Strangely enough, everyone is filled with remorse after I die.
