Ultimate Scheming System Manga

My boyfriend, Allen, is a fitness coach who is cheerful, handsome, and has eight-pack abs. After getting together with me, he transferred all his female students to other colleagues and would send me daily check-in photos. In anticipation of becoming his fiancee, I happily prepared for our engagement ceremony. However, two weeks before the ceremony, I discovered a bright red lipstick mark on Allen’s workout pants. I quickly pulled up the check-in photo he had sent me that day. Through the reflection on a dumbbell, I saw a woman standing next to Allen—her lips painted in the exact same lipstick color. Most of the previous photos had flaws, but I had trusted Allen too much to notice them. Looking at his message under the photo, I let out a cold laugh. "Baby, I have to work overtime today to train a male student." He actually dared to deceive me. Just then, my phone rang. It was the wedding planning company confirming the engagement ceremony setup. I quickly responded with a confirmation. The ceremony would proceed as planned—except I had a special surprise prepared for Allen, one he would never forget.

After confirming I was pregnant, I suddenly heard my husband’s inner voice. “This idiot is still gloating over her pregnancy. She doesn’t even know we switched out her IVF embryo. She’s nothing more than a surrogate for Elle. If Elle weren’t worried about how childbirth might endanger her life, I would’ve kicked this worthless woman out already. Just looking at her makes me sick. “Once she delivers the baby, I’ll make sure she never gets up from the operating table. Then I’ll finally marry Elle, my one true love.” My entire body went rigid. I clenched the IVF test report in my hands and looked straight at my husband. He gazed back at me with gentle eyes. “I’ll take care of you and the baby for the next few months, honey.” However, right then, his inner voice struck again. “I’ll lock that woman in a cage like a dog. I’d like to see her escape!” Shock and heartbreak crashed over me all at once because the Elle he spoke of was none other than my sister.

She is no saint. She is no savior. She is the temptress who thrives on revenge, a woman whose charm is as lethal as her kiss.

I fished my boyfriend from the sea. I empty my pockets to treat his amnesia, and he turns out to be a CEO when he regains his memories. Due to the disparity in our statuses, Quinn Hoffman doesn't hesitate to dump me. He says, "You're just a fishmonger. How can you be worthy of me?" He refuses to pay me back for the money I spent on his treatment. I'm backed into a corner—I need the money for my grandmother's surgery. In the end, I get tricked, and all my organs are gouged out. On the day Quinn learns of my death, he holds my belongings and refuses to let go. "You're just playing hide-and-seek, Kay! Aren't you?"

The day I marry Navy Captain Dean Aldridge, I hear his stepsister Shirley Pierce's inner voice. "Diane is so beautiful and graceful. I wish I could be like her, but I'm nothing more than an unwanted burden in this family… "I really adore her, though. I saved up my allowance to buy her a bracelet as a wedding gift, but I'm afraid she'll think it's unlucky and refuse it." In my last life, those words had filled my heart with pity. I'd accepted the bracelet and even taken Shirley under my wing, teaching her to read and write. But not long after my wedding, my health began to deteriorate for no reason. It wasn't until I lay dying that I discovered the truth—the bracelet Shirley had given me was cursed, and she'd deliberately made me hear her inner voice. She'd long been in love with Dean and was determined to make the Aldridge family hers one day. Now, when I open my eyes again, I find myself back on my wedding day.

Joel Gleason, my childhood sweetheart and fiancé, promised he'd marry no one but me. But then, to help Jenny Swisher, my adoptive sister, get through her depression, he secretly married her. I didn't hesitate for a second before agreeing to marry Conrad Lennon, Jasselton's most untouchable heir, who'd been in love with me for years. After seven years of marriage, he still spoiled me rotten. He clung to me every night like he couldn't get enough. And there was nothing he wouldn't do for me. I really thought I'd found happiness at last. But one day, after we'd slept together, I heard him talking to his best friend. "Jenny's an international best actress now. When are you dumping Jean?" "It doesn't matter. I wouldn't end up with the person I love either way. Besides, I have to keep an eye on Jean. I can't let her ruin all the happiness Jenny worked so hard for." I booted up the computer in Conrad's study and stumbled upon a hidden folder. Inside were over 100,000 photos of Jenny, plus 100 unsent love letters. I'd been fooling myself long enough. It was time to wake up. I got myself a fake body and got ready to start a fire. That was it. Conrad and I were done for good.

In my previous life, the apocalyptic haunts descended without warning, and the whole world plunged into a living hell. After two days of starvation, my husband and mother-in-law tied me to a chair. I begged them desperately, but they did not spare me. Instead, to keep their "food" fresh, they sliced the flesh straight from my leg. When I was reborn, I spent every last cent of my fortune to hold a grand, extravagant funeral, for myself. My husband and mother-in-law thought I had lost my mind. However, what they had not known was this: anyone who buried themselves could claim the treasures laid to rest in their own coffin: golden coins that could command the anomalies of the end times. Which meant that with this extravagant funeral, I would stand invincible when the apocalypse arrived. That time, without me as their "meat" and scapegoat… I would see how long they lasted.

After lights-out, I make my roommates play with an Ouija board with me. Being the scaredy-cat she is, my roommate decides to ask something stupid, "Where did my earphones go?" I almost burst out laughing. I can't believe she's using it to find her earphones. To our surprise, the planchette starts to move. It spells out, "It's under your bed beside the eye." We exchange glances in confusion. What eye? I snort and get out of bed. Using my phone's flashlight, I check under the bed. Nothing is there. Before I can make fun of my roommate for being superstitious, the door slams open. The student who stays next door barges into our room, her face as pale as a sheet. Her voice trembles as she shouts, "Wake up! Everyone on campus is going wild! Someone found an eyeball in our dorm!"

My husband's childhood sweetheart needed surgery, and he insisted that I be the one to operate on her. I followed every medical protocol, doing everything I could to save her. However, after she was discharged, she accused me of medical malpractice and claimed I’d left her permanently disabled. I turned to my husband, hoping he’d speak up for me, but he curtly said, “I told you not to act recklessly. Now look what’s happened.” To my shock, the hospital surveillance footage also showed that I hadn’t followed the correct surgical procedure. I couldn’t defend myself. In the end, I was stabbed to death by her super-alpha husband. Even as I died, I still couldn’t understand—how did the footage show my surgical steps were wrong? When I opened my eyes again, I was back on the day Joanna was admitted for testing.
