Ultimate Scheming System Manga

Before the mission, I ask Ryan Jamison one last time, "Will you marry me?" He pauses for a moment before saying, "Alright." The system and I freeze. "Oh no," we say in unison. I'm told that once I get rejected a hundred times, I'll return to the real world. Turns out, it's nothing but false alarm. In my final mission, I accidentally become the stand-in for his first love. Ryan spends three days with her before he finally remembers me. But by then, all he hears is that I've died in the line of duty.

My boss, Jared Princeton, sends me a contract and tells me that I can only clock out of work if I sign it. I only realize that the contract is The Devil's Contract, binding him and me together in a master-servant relationship, after I sign my initials on it. Just as I prepare to run, Jared appears right behind me and binds me with his Devil tail.

On Valentine's Day, I suggest going to a restaurant to celebrate, but my boyfriend, Michael Nelson, refuses. He says impatiently, "Why should we celebrate some lousy holiday? I don't want to waste good money on it." He turns around and happily chats away on his phone, completely absorbed in the conversation. Then, I hear the system's notification going off in my head. "Congratulations. You have received 2,860 dollars." This means that Michael just transferred 1,430 dollars to his side chick. He doesn't know it yet, but I have a system. It's called the Infidelity Cashback System. Every time he spends money on his other woman, I get double the cashback in my bank account.

In the tenth year of my pursuit of Henry Stone—the profoundly devoted deuteragonist in the novel—he arranges a lavish, extravagant wedding on my behalf. I still feel uneasy even though Henry continues to love me deeply after we get married. This is because the mission progress bar displayed by the system has never moved past zero. On our wedding anniversary, I happen to stumble upon a hidden diary in Henry's desk drawer, which reveals a very shocking truth—Henry has been reborn. He possesses full knowledge that this world is a novel and that I am the antagonist who poses a threat to the protagonist, Renee Schmidt. He puts on a careful act of profound love toward me, strictly for the purpose of shielding Renee, the person he truly cares for. I have just gotten the gist of the whole situation when the system's warning goes off. "You have failed your romance mission. Your existence will be terminated within 48 hours."

Our entire class gets dragged into The Tyrant's Atonement game. The only way to escape alive is to reach a 100% atonement score. The system lets us choose our roles. The class belle, Isolde Adler, picks the tyrant's first love. Her atonement score shoots straight to 99% on the first day. The class president, Asher Brooks, chooses to be a loyal chancellor. His atonement score jumps to 80%. Spectators watching the game flood the screen with comments. "This new batch is smart and way better at picking roles than the last. They might just clear the game in three days." "Even if just one person hits 100%, the whole class goes free. I'm looking forward to seeing who finishes first." "My money's on the first love. She's already at 99%." Just as everyone starts celebrating, the next morning hits us with bad news. All 20 classmates who picked their roles are dead, and Isolde suffers the cruelest fate of all.

After my husband got into a car accident, he started acting strange and unpredictable. I went to countless doctors, and every one of them told me the same thing—he couldn't be provoked, and I had to go along with whatever he wanted. When he said he didn't want me in the master bedroom, I moved my things into the guest room next door. When he said his childhood sweetheart had cancer and he wanted to spend her last days with her, I even brought her into our home. One night, when I went downstairs to get some medicine for my stomach, I heard Harvey's voice, his tone oh so tender. "Katie, you have to live on. If you don't, I'll die too." Katie's breathy, trembling voice followed. "Are you sure Jenna's willing to donate her bone marrow to me?" "Of course. Even if she had to die for me, she'd do it willingly." I froze in place. Tears streamed down my face. That's right. Five years ago, I had donated one of my kidneys to him. Back then, I loved him so much that I really would have died for him. But now, all I wanted was to leave.

My husband, Gideon Huber, is a self-righteous hypocrite. He used my money to fund an impoverished student's education fees, forced me to donate my kidney to a homeless man, and even gave my newborn to a human trafficker. Now that I'm reborn, I finally found out why Gideon had done all those things to me in my past life. Apparently, he was bound to the virtue system in my past life. This time, the system has chosen me as its host. Well then, Gideon, please enjoy the feats of "justice" I shall perform on you!

"I… I can't hold it. I need to use the bathroom." The flight attendant in the interview slumps in her chair. Her face is twisted in pure agony. I've secretly fitted the chair with a vibrator, so the moment I press the switch, it jerks and rattles unpredictably. As I watch their faces turn red and their bodies tremble uncontrollably, a sense of supreme satisfaction washes over me. To my astonishment, one of the flight attendants hitches up her uniform skirt and insists I attend to her needs on the spot. …

After failing the task of winning Spencer Greene’s affection, I was bound to the Perfect Partner System and became his perfect wife. When rumors spread about him and Zoey Xander, I stepped up to clear his name. When Zoey accused me, he let it slide, and I took the blame and apologized. Even when he got Zoey pregnant, I stayed quiet. I calmly handed him the divorce papers and gave Zoey the title of Mrs. Greene. But he was not pleased. He pinned me down on the bed with eyes full of anger. “Zara, I only wanted you to behave! I never wanted you to push me away. “Are you blaming me now?” I froze and stared at him in shock. “Isn’t this what you wanted?”

Don Fiorenzo Ricci saved me and brought me home, raising me for seven years. During the day, he was refined and restrained, treating me the way a true father would. At night, he was endlessly inventive, making me his and his alone. I drowned myself in this twisted love, naively believing I was the only one for Fiorenzo. Then he turned around and married another woman, made her the Madre of the mafia family, and forced me to watch them together. I was done being a piece in their twisted games. The first time I ran, he nearly killed the maid who helped me. The second time I ran, he shot the gardener dead on the spot. The third time, and the last, I jumped into the ocean right in front of him. I did it all for freedom, even if it was only the freedom of my soul after death.
