How Does The Protagonist Level Up In 'The Lust System'?

When the apocalypse came, she lost everything. Starving, hunted, and desperate, she trusted the one man she loved… only for him to betray her in the cruelest way possible. He stole her last supplies to please another woman and left her to die in a sea of the undead. But death wasn’t the end. She woke up days before the world collapsed. After cutting ties with her ungrateful ex and his parasitic family, a mysterious voice awakens in her mind, LUS, a Level-Up System designed to help her survive the coming end. With knowledge of the future and a system guiding her every move, she begins to prepare. She stockpiles resources, builds a base, and learns how to fight back against the horrors that once destroyed her. And when the apocalypse arrives again… she’s ready. But survival isn’t the only thing waiting for her in this new life. A silent killer who watches her like prey. A manipulative genius who wants to unravel her secrets. A gentle protector who sees the girl she hides. And a dangerous man who thrives in chaos. As the world burns and power shifts, they’re all drawn to her, each with their own motives, each with their own darkness. Even her past refuses to stay buried. Because now, the man who once abandoned her is back, broken, desperate, and begging for a second chance. Too bad she has no time for regrets. Not when she’s busy rising to power… and building a kingdom in the ruins of the world.

Left for dead by the man she loved. Reborn with a system built for absolute domination. When the zombie apocalypse hit, Eva’s pathetic boyfriend stole her last scraps of food and fuel to please his mistress, leaving her to be ripped apart by a ravenous horde. But instead of dying, Eva wakes up thirty days before the outbreak, and this time, she’s not playing the victim. With her memories of the future and "LUS" a ruthless Level-Up System echoing in her head—Eva ditches her toxic ex, hoards a fortress of supplies, and builds an unstoppable wasteland empire. Now, her sniveling ex is back on his knees, weeping and begging for forgiveness. But Eva doesn’t have time for a coward. She has a base to expand, a system to max out, and a line of dangerously powerful, fiercely protective alpha "partners" begging for her attention—starting with Justin, the lethal wasteland warlord who refuses to let her go. The world ended once. This time, it belongs to her.

"He was supposed to be cannon fodder. Now he’s the CEO’s obsession.” Sky Templeton thought dying broke was the worst fate. That was until he opened his eyes in the body of a doomed secretary inside a cheesy romance novel he once rage-dropped. The role? Cannon fodder, destined to be crushed under the heel of the cold and ruthless billionaire CEO, Dream Lancaster. But life gives Gloss no time to despair. A mischievous system binds to him with cruel missions: survive 100 days, raise the CEO’s affection score from -1000 to +1000, and…most terrifying of all, rewrite his tragic ending. Gloss only wanted to survive. He never expected to become entangled in office politics, fake dating contracts, or the dangerous pull of a man who despised him. Yet, with every mission cleared, Dream’s icy mask begins to crack, revealing scars and loneliness Gloss never thought a ruthless CEO could carry. Was this just the system’s game, or had fate rewritten both their stories?

My husband, Zane Wade, was drugged at a cocktail party and ended up sleeping with a female college student who looked almost exactly like me. I gave him three chances. The first time, Zane sent the young woman abroad overnight. Then, he knelt outside our home for three days and three nights. The second time, I ran into him and the college student at the hospital. He was accompanying her for a prenatal check-up. At the time, Zane hugged me tightly and refused to let me go. His voice trembled as he said, "I'm sorry, Raina. She's pregnant, and my mother threatened to commit suicide. I have no choice but to keep the child. "I swear, once she gives birth, I'll send her away immediately. The child will go to the old family estate. Please, don't leave me…" But just three days later, because of that same woman, Zane fought me at an auction over my mother's heirlooms. When he saw me raising the bid higher and higher, he immediately went nuclear. This was the third and final chance I gave him. I rushed over to confront him, but Zane wasn't worried. He just frowned slightly and calmly said, "Raina, you know very well that Moira is about to give birth. Why do you insist on fighting a pregnant woman? You only need to endure it for another three months. Then, we can go back to how things were." Upon hearing his words, I almost cried at how ridiculous they sounded. I finally decided to get a divorce, but Zane actually brought Moira Green home openly and without shame.

I've been pent up for far so long that my hormones are going out of balance. So, I decide to visit a massage parlor that my best friend has recommended to me, hoping that I can completely get rid of the sense of emptiness that's inside me. When the young and well-built masseuse begins caressing me with his scalding palms, I feel the flames of lust burning brighter within me to the point they are about to swallow my rationality whole…

Bima is just an introverted, scrawny kid used to living behind a gaming screen and being a constant target for body shaming. But his life takes a drastic turn when he wakes up in a ruined city crawling with zombies. In the midst of the chaos, something even stranger than the apocalypse emerges: the "Single Survival System," which hits him with absurd missions likes maintaining an ideal BMI, getting revenge on his bullies, and landing his first kiss. Every mission isn't just a ridiculous challenge; it’s a matter of life and death. Forced out of his comfort zone, Bima must face his dark past. He crosses paths with Donny, his former bully who is now a zombie, and Kevin, an ex-gym influencer who has transformed into a fanatical cult leader obsessed with the perfect physique and extreme protein intake. Amidst the chaos, Bima meets Lia, a tough convenience store clerk who harbors a deep-seated trauma toward food. Together, they survive nonsensical threats, ranging from zombie food vloggers obsessed with livestreaming death to grotesque mutants lurking underground. But the madness is only the beginning. Bima’s reckless actions catch the attention of a far more dangerous entity: the Master AI Fitness Freak, an artificial intelligence that views humans as inefficient unless they meet extreme nutritional standards. With the help of Riska, an AI with cold, business-like logic that shares a secret connection to Bima’s past, the battle shifts into a clash of ideologies: perfection versus happiness. In a world that worships muscles, protein, and ruthless efficiency, Bima fights back in an unexpected way, using Indomie as a symbol of balance, hope, and humanity.
