Does 'A Weird Revenge Ntr System (Beta)' Have A Happy Ending?

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.”

After I transmigrate into a Gary Stu novel as the evil male supporting lead, a system appears in my mind. It tells me that as long as I can conquer one of the female leads, I will be able to return to my original world with a healthy body. But I've failed in my conquest. There are a few female leads in this novel. There's the fake heiress, Leslie Jackman, who I have grown up with and have viewed as my older sister. The true heiress, Miranda Suller, is a boxer who happens to be seatmates with me during our high school times. My childhood sweetheart, Catherine Langdon, who's also a genius surgeon, happens to be one of the female leads too. Heck, even my own daughter, Natalie Jackman… my own flesh and blood… All of them are quick to fall for Gabriel Linner, the poor yet strong-willed young man who's also known as the Gary Stu of this novel. Because of that, they hate me deeply. The system sighs before telling me that as long as I can die in the hands of any of the female leads, it will let me return to my original world. Later on, I use all of the tricks up my sleeve and succeed in getting killed by the female leads. But why is it that they've lost their minds after I die?

A serial killer targeted me. My sister-in-law was assaulted and murdered while trying to save me. Not only did I refuse to call the police, I pushed my father-in-law and mother-in-law down a flight of stairs when they came to help. I even helped the killer destroy the evidence. When my husband learned that his entire family got killed, he broke down in tears. He grabbed me by the collar and demanded, "Why? Why would you do this?" I deliberately waved photographs of his family's gruesome deaths in front of him and burst into laughter. "Why?" I sneered. "Because they deserved it." My parents begged me to cooperate so I wouldn't be sentenced to death. Instead, I publicly severed all ties with them. Meanwhile, the murderer who escaped justice struck again, claiming another victim. As public outrage reached its peak, I was selected for the Memory Extraction Program. Before the sentence was carried out, my husband asked me one final time, "The Memory Extraction System is still a prototype. You could die during the procedure. "Tell us the truth now, and there's still a chance to make things right." I slowly raised my head to look at him. "You're not getting a single word out of me." The crowd instantly erupted. People shouted that a worthless life like mine deserved to die. But when my memories were finally extracted, they were the ones crying and begging someone to save me.

"I love you, I really really do~ please marry me" I closed my eyes in fear as I kneeled in front of the devil itself who had his hands warped around the female lead. The next thing I knew I stood in the wedding hall wearing the white suit while in front of the Villain itself putting the ring on my finger. "Now I declare you as husband and hu-husband? you may kill your husband" It was supposed to be a straight Otome game where I was supposed to be dead while saving the FL. But here and I married to the villain itself. "WHEN DID IT TURN INTO BL?" I don't own the cover as I just did the editing of the art and credit goes to its owner

On my birthday, my boyfriend ditched his childhood friend's desperate call to be with me. Devastated by his rejection, she spiraled into depression and ended her life. Heartbroken, he proposed to me beside her body. "I've already lost Giselle. I can't lose you, too." I said yes, moved by his grief and sincerity. But on our wedding night, he turned on me, hacking me with a knife. "You vile woman! Giselle died because of you. Time to feel her pain!" As I bled out, the girl waltzed back, saying she'd faked her death to spook him. Overjoyed, he pointed at my corpse. "Thank God, you're alive. This wretched woman is gone, and we're free to be together." They looted my wealth for their lavish wedding and happy life. When my eyes snapped open again, I was back on that fateful birthday.

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."
