I was a corporate slave three years into the grind when I woke up in the body of Sarah—a noblewoman in a novel known for causing trouble, getting universally hated, and meeting a gruesome end.
To make matters worse, this world is in the middle of a zombie apocalypse!
Armed with the experience forged from my days as an office worker, I’m fighting to survive. But wait… the Crown Prince and the Grand Duke, who are supposed to hate my guts, are suddenly obsessed with me? And now everyone is relying on me? It’s total chaos!
Can I overcome this hopeless situation and escape this doomed world? And what is going to happen with my romance with these heroes?!
