I was reincarnated as the heiress of a powerful conglomerate family in a novel. The problem? This world is about to be destroyed by virus-infected monsters. With money being the only thing I had left, I quickly bought a mansion in the countryside to build a bunker and hide from the monsters… But the apocalypse came much faster than I expected—what the hell?! To make matters worse, somehow all the male leads ended up trapped in my house too. But they don’t seem to have any intention of leaving. Why does no one seem interested in going to the original heroine? “Who the hell are you, really?” “Seems like someone who knew the apocalypse ahead of time.” They were full of questions about me, but I couldn’t answer them. Not like they’d believe me anyway. Right now, all I see them as… is useful labor. “Let’s get to work now. You eat, you pay your share!” Once I find the cure for the virus that caused the apocalypse, this hellish time will finally be over. So until then, I’ll survive by putting the male leads to work! But now there's a new problem. Turns out the old mansion I bought is way more suspicious than I thought. What on earth is going on in this house?
