What Clues Explain The Leave The World Behind Novel Ending?

Six years after I allegedly crossed into this world, Liam Locke slid a ring onto my middle finger and suddenly tightened his grip on my hand. "Keira, the whole parallel world story isn't real." He lowered his voice. "It was just an excuse so I could be with two people at once." I went still. He even winked at me, like this was all in good fun. "I never had a childhood sweetheart. Demi's the woman I cheated with. "The day you showed up at the hotel, I made that story up on the spot. You believed it. You actually thought you were the one who didn't belong here and waited for me for six years." My chest clenched tight as I stared at his face in shock. "Then why are you proposing now?" "Call it mercy. We've been together almost eight years." He smiled. "Once Demi goes overseas to study, I'll give you your old life back. What do you say?" I looked at the girl in the distance, the one who had spent the past six years living openly as Liam's real girlfriend. A heavy exhaustion settled over me. He didn't know this, but I had actually come from another world. A world without him.

Floods, tsunamis, heatwaves, acid rain, deep freeze, earthquakes… In her last life, Sophie Zurer survived a grueling eight years after the apocalypse, only for her parents to die tragically while her brother melted in the acid rain. Born again, she avenged her parents, and with a void pocket in hand, she began to stockpile everything from weapons to food, agricultural manuals, and medicine… Eight years later, the city was once again torn apart by earthquakes while the oceans devoured the continents. However, while Sophie survived with her family, the apocalypse cranked up in difficulty as if it were a video game! This time, there were erupting volcanoes, undersea volcanoes, lightning storms, scalding seas, and fireballs falling from the skies… The apocalypse of the land was just the prelude to the apocalypse of the deep sea! Where would humans live when the last island was consumed by the sea?

On my eighth birthday, I begged my mom to video call my dad, who was supposedly working late. The moment the call connected, a version of him from ten years in the future appeared on the screen. My mom held me close and smiled, asking him, "Ten years from now… our Lily has grown up. Was her coming-of-age ceremony a big celebration?" Dad replied coldly, "She kept trying to one-up Sarah's kid, so I sent her abroad. Too bad her luck ran out—her plane went down." My mom's face went pale. On the other end, my dad let out an icy laugh. "Claire, back then, you lied to me. You said if your 'plan' didn't work out, you'd die. I believed you. I gave up Sarah and her child to marry you." My mom's body started trembling. I reached out toward the screen. "Daddy, when are you coming home to celebrate my birthday with me?" Dad sighed and looked at her calmly. "The truth is, I wasn't working late that night. I was celebrating Sarah's daughter's birthday. Now you know everything. What you do next is up to you." Suddenly, a cold robotic voice echoed in my ear: [Host, do you choose to abandon the original world and stay here forever?] I wiped the tears off my mom's face and, barely understanding what was happening, said, "Mommy, does that mean Daddy doesn't want us anymore? Then let's not want him either. Okay?"

The world ended but escaping him was always the harder part. Alone in a dying world filled with abandoned villages, hidden secrets, and creatures lurking in the dark, she fights to survive while running from the man who once destroyed her life. But the deeper she goes, the more she uncovers a terrifying truth connecting her, the village she escaped, and the thing hunting her through the ruins of the world. Some monsters are born after the apocalypse. Others were always human.

Eight years ago, I was transported into this post-apocalyptic power fantasy novel as the same-named expendable nobody. I had the ability to create a large-scale radiation shield that could block zombies. I was the only S-Rank ability user in the entire colony. But because my younger brother, Samuel Grant, failed to awaken his ability, my only purpose became providing him with "upgrade materials." I tried to fight against the story and refused to hand over my crystal core. But the story's inertia twisted everyone's minds. My parents accused me of working with the Zombie King just so they could forcefully transplant my crystal core into Samuel. My ex-wife, Chloe Carter, went even further. While I was unconscious, she personally cut open my chest and took half of my crystal core. I survived. But my spine was severely damaged. My ability circuits were destroyed. I became a cripple who could never stand again. After I was released from prison, I could only work at a chemical protection laundry plant on the outer edge of the colony. Then, a mutant zombie horde carrying extreme radiation surrounded the colony. The old shield generator was burned out by the radiation. Suddenly, my entire family knelt in the dirty wastewater and begged me. "Ethan, you're the only one who can manually guide the remaining power in your ability to repair the shield! You have to save Samuel! He's still fighting on the front lines!" Sitting in my wheelchair, I pointed at the eight-inch scar across my chest. Then I pointed at my withered legs. "The crystal core is inside Samuel's body. My broken spine is buried in the mud under your feet. I can't even stand anymore. And you want me to go into the radiation zone? Are you hoping to watch me die?"

Zach Lawson was one of the novel's male leads. He was supposed to be deeply loyal and devoted to the female protagonist. But somehow, he fell in love with me—an insignificant supporting character. The system decided that he had swerved too far away from the plot and killed him off with a car crash. I made a deal with the system and revived him in exchange for my chance to return to the real world. His legs were useless after the revival, so I took him everywhere just to find a cure. I stayed with him during his recovery, and I did not leave while he worked his way back up. During the company's celebratory event, a reporter asked him what his drive for success was. He smiled gently. "Someone I owe my life to." The edges of my eyes went red, but then I realized he was not looking at me. It was on a woman in the first row, who was wiping her tears away. This novel's female protagonist. The crowd applauded. A system notification popped up. "Five years have passed. The promise is fulfilled. Will you return to the real world?" I looked at him. He was walking toward Rainie Quinton. "What happens after I leave?" "He'll be killed off, like he was supposed to be." "I see," I said. Then I thought, 'I'm leaving, Zach. And this time, it's for real.'
