I Knew I Was Going to Get a Divorce, So I Saved My Ill Brother-In-Law

“Live like a ghost. Don’t do anything weird.”
I possessed a supporting character who lived as a villainess, divorced the male lead, and died.
When I possessed her, her sin had already piled up like a mountain, and she didn’t want to meet a death ending, so I lived live like a ghost, as the male said, and waited for my opportunity to leave.
She treated her younger brother-in-law who had a limited lifespan with her meager stamina, and she sold her belongings to save money for the future.
when her younger brother-in-law’s illness was completely cured, she was about to leave… … .
“Let’s get divorced now.
But since I saved Theo, you’ll at least give me a mansion to live in, right?”
“What do you mean?”
“… … If that’s too hard, a small house is fine.”
“Divorce? Why are we getting divorced?”
Because it was time to give up her place to the female lead?
“Divorce doesn’t exist in my dictionary.”
It wasn’t just the male lead who became strange.
Even her brother-in-law and the mansion staff, who should hate and detest me, clung to me.
“Where are you going, Sister-in-law!
“If my sister-in-law disappears, I will die without even eating!”
“If the lady is not here, this mansion will become a mess. Don’t leave, my lady!”
Is this the destruction of the original?
It can’t be helped. That’s what happened… … .
