I’m a Former Office Worker Who Became the Villainess in an Apocalyptic World ~I’ll Survive Using My Corporate Slave Skills~

I was a corporate slave in my third year at work when I woke up to find myself transmigrated into a novel—as Lady Sarah, a troublesome noblewoman (duchess) who does nothing but cause problems, ends up hated by everyone, and meets a horrific death. To make things worse, this world is an apocalypse overrun with zombies. Armed with the survival skills she honed as an office worker, Sarah struggles to stay alive—but for some reason, the Crown Prince and the Grand Duke, who are supposed to despise her in the original story, start becoming strangely obsessed with her. She even ends up turning into someone everyone relies on… and everything spirals into total chaos!? Can she overcome this hopeless situation and escape the end-of-the-world wasteland? And where will her romance with the heroes lead?
