My best friend, Aria Sinclair, develops amnesia after killing my parents in a drunk-driving accident. Somehow, everyone forgives her. My own brother signs a letter of forgiveness on her behalf. The son I nearly died bringing into this world affectionately calls her "Ari". Even my lawyer husband of eight years stands in front of her and defends her. Because I insist on taking her to court, they join forces and have me committed to a psychiatric facility for an entire year. On the day I'm released, Grant Berton comes to pick me up. He says, "Aria has lost her memory. She's changed and turned over a new leaf. Do you really have to demand a life for a life? Can't we forget the past and move on together?" Voices rise around me from every direction, all urging me to let go and forcing me to forgive. I look at the people who are supposedly the closest and dearest to me. Then, I calmly utter one word. "No." This time, I don't scream and rage about sending her to prison. Even when I catch Grant and her together in the bedroom, I don't pick up a knife and drive them out. Instead, I silently speak to the system in my mind. "I give up on the mission." I don't want the wreckage of the past, and I have no interest whatsoever in a future without light.

On our third wedding anniversary, Kent gave me a gift. A black metal wristband. Cold. Sleek. He called it a new product from his company—a pain-sharing system. The other user was Violet. His "girl bro." The person he was closer to than his own sister. Kent brushed a hand over my cheek, his gaze soft. "Clara, you're too coddled. You should learn from Violet. She's tough." Then he snapped the wristband onto my wrist. So while Violet got a full-back tattoo and an entire sleeve, I felt every single needle. When Violet went wingsuit flying, I collapsed at home. Every bone in my body felt shattered. I threw up blood. While she soaked up attention online as the "extreme sports queen," I was drowning in nonstop pain. Kent sat beside me, holding my hand as he cared. "Just hang in there. Violet's just being herself. As my wife, you should be more understanding." To finally push me over the edge, Violet decided to livestream herself jumping into the ocean to make me die in her place. Their friends couldn't wait to watch. Later, I watched calmly from a hospital room as the system slowly drained the life out of her. Kent looked deranged as he demanded to know why I wasn't dead. Because I had already reversed the system. All her vitality had become the nourishment that sustained me.

Nine years ago, Charlotte Green willingly bound herself to a companionship system to save her sister. The system guided her to the side of Eric Lorvis, a man adored by fate and envied by the world. Her role, as dictated, was to pursue him under the guise of being mute. Before long, everyone in their social circle knew of the mute woman who loved Eric with a fervor bordering on madness. At a gathering one evening, he finally relented. "If you make yourself look like Emily, I'll allow you to stay by my side." Without hesitation, Charlotte borrowed money to undergo plastic surgery. She reshaped herself to resemble Emily Spencer—Eric's first love. With painstaking precision, she molded her preferences to match his, learned to cook his favorite dishes, and catered to his every need. Yet to him, she was no more than a housekeeper. He neither hid his disdain nor spared her his indifference. His insults, his cold stares—she bore them all in silence. She didn't care. As long as she fulfilled her task, the day would come when she could finally leave this world behind. However, when Charlotte truly died, the cold and aloof Eric, who had always appeared so composed in front of others, lost his mind...

On the day of our daughter's full-month celebration, Harvey McKinzie walked onto the stage holding the hand of his widowed, heavily pregnant sister-in-law. "Honey, to be honest with you—my sister-in-law's baby is mine." His parents followed behind, looking completely unapologetic. "We're the ones who made it happen. We drugged them. Our oldest son may be gone, but the family can't be without an heir. "Harvey is taking on the responsibility of carrying on both family lines—it hasn't been easy for him. From now on, you need to take good care of Lydia and the child she's carrying." The sister-in-law, now eight months pregnant, glanced at me shyly. "Jennifer, we're sister-wives now." I stood there frozen, holding my daughter, my voice trembling. "Why are you doing this to me?" Harvey frowned and let out a long sigh. "You're always saying how hard Lydia has it, right? Isn't it better if I just take care of her openly and properly? "I promise—you'll be the first wife, and she'll be the second. On paper, you're still my only legal wife." In that moment, my blood ran cold. Then, for the first time in a long while, I heard the system's alert in my head. [Host emotional fluctuation detected. Would you like to use all remaining points to exit the current world?]

Seven days after my twin sister Bianca suffered cardiac arrest and slipped into a coma, my fiancé Matteo De Luca sat beside her ICU bed, holding her cool hand through the night. “So you were telling the truth.” “If I don’t marry you, you really will die.” “Bianca, wake up, and I’ll marry you immediately.” After his promise, her pulse quickened on the monitor, and Bianca opened her eyes. Everyone called it a miracle. Only then did I learn that Bianca was a Contract Holder, and the man she had been assigned to win was Matteo—the man I had loved for five years and was about to marry. His promise had only stabilized her. According to Bianca, the contract would not be complete until the marriage became legal. That same night, our two mafia families rewrote the wedding plans. The De Luca chapel remained booked. The reception, guest list, and priest stayed the same. My mother placed the De Luca heirloom veil that had been fitted for me on Bianca’s head, my father ordered the lawyers to replace my name on the marriage documents, and Matteo slid my engagement ring onto her finger. They were relieved that Bianca had survived and assumed I could wait. Standing outside her room, I watched Matteo kiss her hand as the system spoke inside my mind. 【Target individual is preparing to marry another Contract Holder.】 【Original task entering failure countdown.】 They did not know I was a Contract Holder too. Bianca and I had received the same task, with the same man as our target. She was awake. Now I was the one marked for erasure.

My husband, Theo Hudson, is known for being very frugal. After marrying him, my only hobby is to keep buying branded bags, just to get back at Theo for being extremely stingy with his money. When our son, Oliver Hudson, is seven years old, he has successfully inherited the tendency to be overly frugal from Theo. Both father and son look very out of place in the sprawling manor. I, on the other hand, love wearing anything from the haute couture selection of the season while admiring the heartbroken expressions on Theo's and Oliver's faces when they see the bill. But one day, live comments begin streaking across my eyes. "Wait, this wasteful woman is still splurging on bags? Does she have no idea that her husband's company is about to file for bankruptcy?" "The poor male lead has already worn his T-shirt so many times to the point it's starting to fray just to sustain that vampiric wife of his! Thank goodness the female lead, who's brilliant with finances, is about to enter his life!" "I shall wait for Theo to bring up divorce and kick that useless hag who does nothing but spend his money out of his life! Let's see how she's going to fight for scraps with the strays beneath the bridge in the future!" I'm so shocked that I hurl the limited Hermes bag I was clutching in a random direction. Unfortunately, Theo, who's crouching on the floor while opening the packages for me, and Oliver, who's flattening the boxes by stomping on them, get hit by the bag. Scared out of my wits, I quickly snatch the cardboard from Oliver's hands and hug it tightly. "I… I'm not buying these bags anymore! Let's get a refund! But keep the cardboard boxes and don't sell them! I… I want to use them as makeshift mattresses for when we're about to sleep under the bridge in the future…"

I'm a bad-luck magnet in showbiz. Every guy who gets paired with me for publicity ends up with his image wrecked and career destroyed. And somehow, I still just want to fall in love. I finally landed a romance game endorsement, but I had no idea I'd accidentally wandered into a horror game. During the beta test, I threw myself straight into the BOSS's arms—a general. "My love, I missed you so much!" He froze in shock, his mangled hand moving toward the sword at his waist. I shyly stopped him. "Wow, slow down. We literally just met, and you're already trying to take your pants off?"

After five years of marrying into the Loween City in place of my sister, the Gambling King finally passed away. My son and my ex-husband—at long last—gave me permission to fake my death and return to them. But they laid down three conditions. First: kneel before Vivian Gray, apologize for framing her all those years ago, and surrender my place as Mrs. Hartwell. Second: work as a live-in maid for my own son for five years, and never show up at his school in my former identity as the reigning queen of the nightlife scene—lest I embarrass him. Third: drink an abortifacient to destroy my fertility forever, as recompense for the infertility I once caused Vivian. "My lady, you've endured five whole years just to earn your freedom—how dare they humiliate you like this?" My maid's eyes were red, burning with indignation on my behalf. But I just tipped my head back and swallowed the death-faking pill, letting the servants toss my "corpse" into the overgrown brambles beyond the city limits. Then, from the mud and weeds, I crawled back to the Hartwell mansion—one knee at a time. Day one, I knelt as ordered and signed over custody of my son without a fight. Day three, I locked myself in the storage closet and stopped showing up at school to pick my son up like I used to. I also stopped pestering him to call me "Mom." Even when Vivian—knowing full well I'm terrified of the dark—deliberately trapped me in the basement, I bore it in silence. By the time my ex-husband Nathan Hartwell saw me again, I was barely hanging on. For the first time, a flicker of panic crossed his face as he carried me out of that basement. But my son just sneered. "It's just another stunt to win our sympathy." When he caught the tears welling in Vivian's eyes, Nathan coldly dropped me to the ground. "Always scheming against Vivian with your dirty tricks—aren't you tired of it?" Right then, the system chimed in my ear: [Please proceed to the "disposable ex-wife death node" to complete the story line and return to your original world.] I let out a quiet laugh. "Not tired at all." And with that, I turned and dove straight into the swimming pool beside me.
