Human System Manga Novels & Stories

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?]

I had regressed ninety-nine times, and it all started because I brought home an injured man. Every time I came back, strange floating comments appeared in front of my eyes. I could also hear my baby brother's thoughts. The moment my brother saw Tristan Price, he screamed and refused to stop crying. "Send that man back! He's going to get our whole family killed!" I reached out hesitatingly toward Tristan, and the chat overlay flickered to life again. [The man lying in your bed is your future husband and the prince regent. He never forgets a kindness. Save him, and he will make you his princess consort. Your entire family will be protected and well provided for.] The first time, I followed my heart and did what the messages told me to do. I saved Tristan, and he used me as a human shield. The assassins hunting him found us, and my entire family was slaughtered. The second time, I listened to my brother instead and sent Tristan back where I found him. His men came to our door anyway, accused me of leaving him to die, and killed everyone. The third time, I found Tristan's closest aide before the assassins arrived and quietly handed Tristan over. Then Tristan went mad without warning and stabbed me himself. When my family tried to avenge me, they were killed too. I tried every approach I could think of to avoid my family's tragic fate, and every single one ended in failure. This time, I chose to wait for death. Then the comments appeared again, and something about them caught my eye.

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.

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...

After my family joined hands to send me to prison for three years, I start learning how to behave myself. I do whatever everyone else tells me to do. The day I'm released from prison, my wife, Regina Johnson, sits in the car and says coldly, "If you ever lay those hands of yours on Ty again, I'll…" Before she can say anything else, I jump out of the car, pick up a brick from the side of the road, and smash my hand into a pulp with it. Regina stares at the bone sticking out and goes pale. When we get back home, Tyler Lowe, my adopted younger brother, ambushes me in the bathroom and scoffs. "So what if you're the biological son of the Lowe family? I can just as easily have you kicked out of the family!" Then, he uses a blade to make a small cut on one of his fingers before crying out in alarm, "If you really hate me, Cal, I'll leave right away! Please don't kill me!" Regina and my older sister, Calista Lowe, enter just in time to witness his display. Shaking with anger, they stomp on my wound with their high heels. "You haven't changed one bit! If anything happens to Ty, I'll make you pay for it with your life!" I nod obediently and march straight to the kitchen, where I jump into the massive meat grinder before turning it on. The blood and bits of flesh spray all over Mom and Dad, who end up walking in right then. Mom lets out a shrill shriek before fainting, while Dad forces himself to remain composed as he turns off the power. At this point, even Regina, my sharp-tongued wife, can't find the words to say anything. She stands frozen, her body trembling. When we're inside the ambulance, Tyler clings to Regina, quivering as he says, "This has nothing to do with me! He jumped into the machine himself. You have to believe me!" It's almost impossible for me to stay conscious through the unbearable pain, but I muster the strength to nod along with him. After failing to win over my family, I'd spent three years in prison. Later on, the system told me that if I showed absolute obedience until the day I died, I would receive massive financial compensation and be transported back to my original world.

I was the kind of girl everyone called hopelessly lovestruck. That day was no different from any other. I clung to my boyfriend’s arm, leaned in close, and shamelessly asked for a kiss like I always did. However, right before my lips touched his, a line of glowing comments drifted across my vision. They floated in the air like a livestream chat. [Can this side character wake up already? Can she not see the male lead avoided her the entire time? He hated clingy relationships like this.] [The kind of person who really suits him is the female lead. Someone gentle, patient, and understanding.] [Once the real female lead shows up, this annoying clingy girlfriend is definitely getting dumped.] My body froze. I slowly loosened my arms from around his neck. In the next second, he suddenly looked up at me. “Why’d you stop?”

I fail my mission and jump off a building to restart the game. Then, I become a billionaire and am rewarded with a handsome young man as soon as the game starts!

Everyone in the mercenary group knew just how deeply Liam Smith loved me and feared losing me. He even suppressed his dark desires to make sure I felt truly safe. No matter how dangerous the mission, he made sure to check in every single day. Worried for his safety, I hid my identity and secretly became his team’s hacker. However, after one mission, I overheard the others joking over the radio: "Chief was in such a rush to pick that lock and go after Wendy. What's so irresistible about her?" Through an unattended monitor, I caught Liam glancing at the camera with a teasing smile. "Didn't I tell you guys that she nearly wrung me dry the last time we did it?" It felt like I had fallen into an ice-cold abyss. My heart shattered, and I summoned the system. [I want to leave this world.] The cold, mechanical voice replied without delay: [Once you leave, all traces of the host in this world will be erased.] [Starting the countdown: Seven days left.]

My mother was a player in a quest. Once her mission was a success, she exited this world, leaving me behind with four fathers. The first was a billionaire CEO. The second was a famous movie star. The third was a world-renowned doctor, while the fourth was incredibly powerful and influential. My four fathers spoiled me rotten for sixteen years, giving me everything I ever wanted. That was until three years ago when Sadie, the daughter of the one that got away, returned. Since then, my four fathers believed her over me. Sadie claimed that my mouth was filthier than a dog’s, so they threw me in the dog kennel and fed me dog food. When she accused me of rallying the other students and bullying her in school, my fathers got me expelled and hired three street gangsters to beat me up for months. Once again, Sadie insisted that I pushed her, and as a consequence, my fathers locked me in a cage for three whole days in the name of teaching me a lesson. As I lay there in hunger, my mother’s voice rang in my ear. “Niamh, do you want to come back to Mommy?”

I'm bound to a rebound system by nature. Everyone who has come up with rumors about me will receive backlash in return. When I was in high school, a male classmate had spread rumors about me being a prostitute who had intimate relations with a few old men. That very same day, he was taken away by a dozen or so old men and was modified into a gigolo himself. When I was in college, my boyfriend's childhood friend spread rumors about me being the female lead in porno videos. That night, all of the available porno videos on the Internet featured her as the female lead. Since then, no one dares to gossip about me. That is, until I'm reunited with the wealthy Hartley family, which happens to be my biological family. The fake heiress, Claire Hartley, takes my hand while adopting a friendly expression. "Hey Amanda, I heard that you got pregnant out of wedlock and gave birth to a murderer's child. Now that you're back, why didn't you bring the baby home with you? "We're a family, after all. We won't look down on you."
