After being reincarnated into the body of a novel's wealthy heiress, Cherry Sinclair quickly realizes that the world is coming to an end, but she’s determined to survive the apocalypse, no matter what. Using the money that came with this new life, she devises a plan to create a shelter to hide from the monsters. What she does not expect, however, is for the male leads of the novel to also end up in the same house! Will all of them be able to work together to survive in this chaos? --- I reincarnated as the heiress of a powerful conglomerate family in a novel. The problem is, this world is about to be destroyed by monstrous viruses. With nothing but money to spare, I quickly bought a mansion in the countryside to build a shelter to escape the monsters… But the world ended far sooner than I had anticipated. Damn it! = On top of that, somehow, the male leads ended up trapped in my house with me. And these guys don’t seem to have any intention of leaving. Why do they look like they have no plans to go to the female lead? “Who exactly are you?” “You seem like someone who knew the world was going to end beforehand.” They were full of questions about me, but I couldn’t answer them. They wouldn’t believe me anyway. Right now, all I see them as is a good source of labor. “Alright, let’s work. You need to earn your keep for what you eat!” If I can find the cure for the virus causing the apocalypse, this hellish time will finally end. So, until then, I’ll make use of the male leads and hang on! = But one problem has come up. It turns out that this old mansion I purchased is far more suspicious than I thought. What on earth is happening in my house?
