How To Write A Background Character That Survives In Manga?

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 am dead. Only before my death do I realize that I am the sidekick in a tragic coming-of-age story, while my best friend Tinsley Wood is the female lead.

When I open my eyes again, I am reborn on the very first day Tinsley asks me to take the blame for her.

In a drought-ravaged apocalypse, I kept our entire apartment block alive with my “watermaker” ability. But when I grew weak, my neighbors shattered my limbs and turned me into a living water source. Later, when raiders stormed in, they dragged me out to take the blade for them, only to realize that even my severed arms could still produce water. So, they shouted about “saving humanity,” then shoved me into the crowd and fled in the chaos. People rushed forward one after another, tearing at my flesh. But I didn’t die. What was left of me fell into the hands of a monster, and I was subjected to inhuman torment day after day. Ten years later, when the apocalypse finally ended, that monster tossed me into an incinerator. Only then did I die. When I opened my eyes again, I had returned to the moment I first awakened my ability, just as my neighbor knocked on the door, begging for water.
