I reincarnated as the heiress of a tycoon in a novel. There was just one problem: the world was doomed to collapse due to a monster virus. Since money was all I had, I rushed to buy a mansion in the countryside and started building a shelter to avoid the monsters... But the world fell apart even quicker than I expected. Damn it! On top of that, somehow, the male leads ended up trapped inside my house with me. And yet, these bastards don't seem all that inclined to leave to find the female lead. Why do none of them act like they have any intention of finding her?

"Who the hell are you?"
"You seem like you knew the apocalypse was coming."

They had a lot of questions for me, ones I couldn't answer. They wouldn't believe me, anyway. For the moment, they were nothing more than convenient sources of labor.

"Alright, time to work. If a man will not work, he shall not eat!"

If I can just discover the cure for the virus that caused this, then this nightmare will end. Until then, I'll just work the male leads to the bone and endure! But then came a bit of a snag. It turns out this old mansion I purchased is hiding something incredibly suspicious. What in the world is going on in my house?!
