Male Leads Trapped in Our House

I was reincarnated as the heiress of a chaebol family in a novel.

The problem is that this world is about to be destroyed by virus monsters.

All that will be left is money, so I quickly bought a mansion in the countryside and was building a shelter to avoid the monsters...

But the world ended much faster than I expected, damn it!

On top of that, somehow the male leads got trapped in our house too.

But these guys have no intention of leaving.

Why do none of them even seem to want to go to the heroine?

“What on earth are you?”

“You seem to be someone who knew the world would end in advance.”

They were full of questions for me, but I couldn’t answer them. They wouldn’t believe me anyway.

To my eyes, they were nothing but useful labor resources.

“Let’s get to work now. If you’ve eaten, earn your keep!”

Once I find a cure for the virus that caused this world’s destruction, this hellish time will be over.

So until then, I’ll just keep exploiting the male leads and endure.

But one problem comes up.

This old mansion I bought turns out to be extremely suspicious.

What on earth is happening in our house?
