The Hidden Dungeon Only I Can Enter Vol. 6 Ending Explained?

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 his first love died, Oscar hated me for ten years. I tried everything to soften him. Nothing worked. "If you really want to please me, go die." The words cut deep. But when the riot came, he threw himself in front of me and was hacked down where he stood. He stared at me as he bled out. "If only… my fated mate hadn't been you." At his funeral, his parents wept. "We should have let him be with Catherine. We forced him to marry her, all because of that damn prophecy." Windvale Pack lived by prophecy. Years ago, the Seer had foretold that if Oscar didn't take his fated mate as his bond-mate, disaster would fall on the pack. I was that fated mate. But now, everyone wished I never had been. Even me. I was driven from the funeral, hollow. Then the Moon Goddess descended. She offered me a chance—ten years back—on two conditions. I would not become Oscar's mate. I would prevent Catherine's death. I said yes without thinking.

I'm a succubus who gathers energy by clearing System missions, adept at the game of love. One day, right after completing a honey trap mission, I was sent to a SSS-level horror game at the very next second. The boss was invincible and bloodthirsty, watching coolly as other players rested in pieces before turning to the rest of us. "Now choose—how do you want to die?" While other players were wetting their pants and trying to find a loophole to survive, I picked up on something different. A handsome, powerful target beneath that cold, horrific exterior. Hence, when he reached me, I smiled enigmatically as I told him my wish. "I wish to be conquered by a truly powerful Entity, dominated from soul to flesh, and to die in pure ecstasy." I watched him pause in shock and added, "Oh, and you must do it yourself."

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.”

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.

After being reincarnated as the villain in a story where everyone doted on the heroine, the system appeared. It told me that if I could win over any one of the male leads, I would regain a healthy body and return to my original world. But I failed to win over any of them. There was my adoptive brother, the fake heir, who grew up with me. My rebellious high school deskmate, the real heir, who became a boxer. And my childhood sweetheart, the genius surgeon. Even my own son, whom I carried for ten months. Without exception, they all fell in love with that cold, stubborn damsel while growing to deeply despise me. The system sighed and told me that if I could die at the hands of any one of the male leads, I would be able to see my parents in the original world. In the end, I used every method possible and was finally killed by them, with their own hands. But why did they all go mad afterward?
