Is There A Romance Subplot In 'Overpowered Villain Returnee In The Apocalypse System Is For Losers'?

My boyfriend stole my last food and fuel, abandoned me to a zombie horde, and ran off with his mistress. Then I woke up three months before the apocalypse. This time, I’m taking everything for myself. Armed with memories of the future and a mysterious Level-Up System, I escape to the mountains, build a fortress, recruit dangerous allies, and carve out a kingdom in the ruins of the world. Now the man who betrayed me wants forgiveness. Unfortunately for him, I’ve become far more dangerous than the undead.

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.

The end of the world was upon us, but there weren't enough spots for evacuation. The roars of the zombies echoed in my ears as my fiancé, Oliver, gritted his teeth and pulled me onto the rescue vehicle—securing the last available seat. I arrived safely at the survivor base. Lina, his first love, did not. The zombies tore her apart. Oliver still went through with our marriage, but I never expected that he had only done so to make me suffer. In his eyes, I was the one who had killed Lina. If she had to endure such agony, then I should, too. For five years, he hated me. My life was worse than that of a stray dog scavenging for food on the street. On the day my divorce was finalized, he kidnapped me, dragged me into the wilderness, and wrapped his fingers around my throat. Then, he threw us both into the swarm of the undead. When I opened my eyes again, I was somehow reborn on the day the apocalypse began. The rescue team was shouting impatiently, "One more! We have room for one more—hurry!" I turned to Oliver, watching his hesitation. Then, with a quiet smile, I took a step back and let someone else have the last seat.

I get reborn, this time bound to a simp system. In my previous life, when the apocalypse happened during Christmas Eve, I gave Victoria Blake, a beautiful woman, shelter and respite, only for her to backstab me in the end. Apparently, she had revealed my home's location to a scion named Tristan Cole when I wasn't paying attention. Not only did those bastards take over my shelter, but they also tossed me to the zombie horde. When Tristan asked Victoria if she felt guilty, she just reclined in his arms while tittering daintily. "That's just one of the lapdogs I've reared. If he's dead, then so be it." Now that I'm given a second chance at life, I'll make sure to repay them for the pain and hurt they've caused me in my previous life.

I had just found out I was a perfect match and was preparing to donate a kidney to my wife’s foster brother. That night, he left his iPad in the living room, and the screen lit up with a chat history between him and a doctor. “Doctor Evans, whatever you do, don’t tell my brother-in-law,” the message read. “If his kidney is removed, his hidden heart condition will flare up, and he won’t last three months.” The next day, I decisively canceled the donation. My wife was furious, calling me cold-blooded and forcing me to sign a divorce agreement that left me with absolutely nothing. A day later, I overheard his smug laughter from outside his hospital room. “He’s so stupid,” Boyd said. “I just photoshopped a fake chat log, and he actually believed he was sick. Now, we’ve stolen his luxury penthouse, and we can finally be together out in the open.” My wife kissed him. “Good boy. I’ll buy you a better kidney on the black market later.” Standing outside the door, I sneered. Of course, I knew the record was fake. After all, I had just reincarnated from the future. In half a month, a zombie apocalypse would strike, and this toxic pair of secret lovers would not only steal my medicine but also throw me to the undead. This time, with only three days left before the city is overrun by zombies, I want to see something. I want to see exactly how many days a sick bastard without a kidney transplant and a heartless woman without any survival supplies can last inside my luxury penthouse.
