Are Overpowered Book Protagonists Unrealistic?

It was the tenth year of the Mechanical Civilization. My girlfriend, who always spoiled her brother to an unreasonable extent, orchestrated my death. Luckily, I was reborn seven days before the arrival of the machines. I bought a heavy-duty truck and evolved the strongest mecha. Close-combat mecha, long-range mecha, weapons, shields, funnels, modules… This time, I wanted the best of everything. My name is Victor Wild. Born to be a victor, born to be wild.

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.

After transmigrating through three novels in a row, the hardest thing I ever suffer through is drinking iced long black. But when I open my eyes again, I somehow become the pathetic simp side character in a trashy romance novel. Just as I debate whether to file a complaint against the system, the trembling system hurriedly explains something to me. Although this is a trashy romance novel, it is also an unfinished abandoned novel. I ask, "So you're saying I decide how the story develops?" The system replied, "Yes. Everything is completely under your control." Satisfied, I lazily stretch and begin checking the original Jacob's background. He has a trillionaire father and a billionaire mother. On top of that, he has seven rich and beautiful older sisters. With such a ridiculously overpowered setup, how can he go around simping for a broke college girl with no money? What a complete waste!

"Did you just lie to me?" He asked in his lowly yet furious voice. She felt shivers running down her spine, as her heartfelt sinking. She tried to speak but couldn't find her lost voice, but she knew if she keeps him waiting, it could be dangerous for her, so she shook her head in a 'no'. But unfortunately, it was not convincing enough as he approached her, making her take a step back. Smiling sadistically at her whimpering body, he towered her. He licked his dried lip, sensing her fear and lowered to her level, purring in her ear, "On my lap, baby doll." ~ 𝐒𝐔𝐏𝐄𝐑 𝐏𝐎𝐖𝐄𝐑𝐄𝐃| 𝐃𝐀𝐑𝐊 𝐇𝐔𝐌𝐎𝐑| 𝐃𝐄𝐍𝐈𝐄𝐃 𝐋𝐎𝐕𝐄 ~ LOONA, University of Heros was established by dark Queen herself, in order to protect the super-powered kids, until and unless they are capable enough to protect themselves but others as well.
