Is 'I Secretly Installed' A Horror Novel?

I’m the heroine in an erotic story. My specialty? Turning anything hot or cold into something steamy. On the first day I landed in a horror game, the boss told everyone to choose how they wanted to die. I smiled and said, “I’ll take shortness of breath, trembling legs, glazed eyes, and… pleasure so intense I die from it.” Boss: “???”

When my boyfriend claimed he was the final boss of a horror game, I laughed it off. What kind of terrifying final boss spends every day at home doing laundry, cooking meals, handing over all his money, and constantly clinging to his wife for affection? Then, one day, I entered the horror game myself. The infamous final boss, the one every player feared, pinned me against the headboard, slowly testing the limits of my body. He leaned close to my ear and whispered, “So? Do you believe me now?”

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.

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.”

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.

For the sake of that fake heiress, my biological parents and brother threw me into a horror game to "teach me some manners." The second the game started, the fake heiress, Nicole, went out of her way to provoke the ghosts nonstop. Once she'd pissed them off, she shoved me in front of her to take the punishment. As I lay there, tortured within an inch of my life, she planted her foot on my head and smirked. "Mom and Dad already made it clear—I'm the only one they truly love. They only brought you back to keep me entertained! Letting you deal with those ghosts for me is more than generous. If you dare complain, once my brother and the others get back, they'll skin you alive." In my past life, I treated them like family and gave in every single time. In the end, I was nothing but a stepping stone for them to beat the game—torn apart and devoured by over a dozen ghosts. But now, I've been reborn. "Welcome to Horror Instance: Happy Home." The moment I heard that mechanical announcement, I slapped the arrogant Nicole so hard she flew across the room. Because in this instance, the three bosses that terrorized every player… were all my family. The red-dressed female ghost who killed without hesitation was my adoptive mother. The monster with scissors for hands who ripped out hearts with a single swipe was my adoptive father. And the ruthless warden who devoured people whole, leaving no bones behind, was my adoptive brother. With them watching my back, why the hell would I keep putting up with this? A mocking smile curled across my lips as I said, "You're on my turf; none of you are getting out alive."
