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?
