I transmigrated in the body of the heiress of a tycoon.
There was just one problem: the world was doomed to collapse due to a monster virus.
With money to burn, I quickly bought a mansion in the countryside to create a shelter... but the world fell apart even quicker than I expected. Somehow, I ended up trapped inside with the male leads, and these damn bastards won't leave my house!
Why do none of them want to seek out the female lead?

"Who are you?"
"She seems like she 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 good sources of labor.

"Let's get to work. You need to earn your keep!"

If I can just discover the cure for the virus that caused this, then the hell I'm in will be over. I'll work the male leads to the bone until then!
But there's a bit of a snag. It turns out this old mansion I purchased is weirdly suspicious.
What in the world is happening in my house?!
