I’ve been reincarnated as Sienna Winter, a minor villainess with a terminal illness in a novel.

My only goal is simple:
To survive without dying!
But then...

"I am Helares Eckbert. You are the one who awakened me."
"…Excuse me? Who are you?"
"Nice to meet you, master."

I accidentally awakened a sealed demon.
And as if that wasn’t enough, I got tricked into a fraudulent contract?

"This contract is valid until you die."
"…Pardon?"
"It’s a lifetime contract, you naïve little lady."
"…But I’m terminally ill?"

Can I really survive in this situation…?
