Is Corpse Party: Tortured Souls Based On A 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: “???”

After entering a horror game, I, Anastasia Moreau, begin dating the big boss. At our first meeting, I wrap my arms around his sleek, serpentine body and squeeze him into a corner of the coffin. "Move over, move over." In the next instant, a strikingly handsome young man with white hair and golden eyes appears beneath me. The tips of his ears flush red as he glares at me. "You… You're lying on my hair!" he grits out.

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.”

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.

On the day before the college entrance assessment, my three childhood friends have gone missing collectively. Because of that, my phone is swamped with phone calls. The parents of my missing friends keep wailing to me, "We've worked so hard our entire lives just so our sons can get into a great university!" My homeroom teacher, Mr. Levinski, begins pressuring me. "You're the class president, so you must find them! The college entrance assessment is a vital event that can determine how one's future will turn out!" Even my classmates and my neighbors keep texting me for more updates. But what they don't know is that I've already hung up on my friends' phone calls for help by using my revision for the assessment as an excuse. In my previous life, my childhood friends had already gotten bewitched by Lucille Reyes, a delinquent. They insisted on celebrating their coming-of-age ceremony at a nightclub because of her. I accidentally overheard Lucille plotting with her delinquent friends that they intended on taking nudes of my friends and extort money from them so that they couldn't attend the college entrance assessment the next day. So, I did everything I could to stop my friends, only to get kicked to the side. "Don't stop us from pursuing true love!" For the sake of my friends' future, I informed their families at once and had them brought into the exam venue by force. Finally, all three of my childhood friends got into prestigious universities. But Lucille, on the other hand, got beaten to death by the delinquents because she couldn't pay her protection fees due to her scheme getting foiled. My friends broke down mentally because of her death. They then decided to pin the blame on me. On our freshman year, my friends treated me to some drinks out of "gratitude", only for them to spike my drink. Later on, they tossed me to the same group of delinquents, who violated me in an alley. They even had the gall to record everything from the alleyway while keeping an eye out for the police. Thanks to them, my future was completely ruined. My parents committed suicide out of despair. To rub salt onto my wound, those friends showed up at the hospital with the video and backed me into a corner once again. "You owe Lucy this much!" In my despair, I ended up jumping off the rooftop. When I open my eyes again, I've returned to the day before the college entrance assessment. As I watch my friends excitedly discussing the nightclub party behind my back, I can't help but smile. In this lifetime, I choose to lock my door and sign the guaranteed admission agreement meant for Mephton University, the most prestigious university ever, without any hesitation. As for my so-called friends, they can enjoy their coming-of-age ceremony in hell.
