NEW Former Office Worker Becomes an Apocalypse Villainess ~I’ll Survive with Corporate Skills~

I was a corporate slave in my third year at the company when I woke up to find myself possessing Princess Sarah—a character from a novel who causes nothing but trouble with her annoying behavior and eventually meets a tragic death after being universally hated.
To make matters worse, this world is in an apocalyptic state overrun by zombies!
Sarah tries to survive using the experience and skills she developed as a hardworking office employee. But somehow, the Crown Prince and the Grand Duke—who were supposed to hate Sarah—begin obsessing over her instead. She even becomes someone everyone relies on… Total chaos!?
Can she overcome this desperate situation and escape from the apocalyptic world? And what will become of her romances with the heroes!?
