The Indebted Descendant of the Strongest Family

I was executed for treason. When I opened my eyes again, somehow, I was thirty years in the future inside the body of one of my own descendants.
What’s left of the family? A mountain of debt. (Negative 833 billion won, to be exact.)
The only things crawling around are bugs and leeches.
The money and businesses I built up in my last life? Gone. Completely wiped out. Like Dorma** and Do**mamuda. Goddamn it!
*
All I wanted was to pay off the debt and become a rich, lazy bum. But then—
“What do I have to do to make it happen? I don’t want to be a contract dad but a full-time one.”
Why is the contract dad acting like this?
“I like Eve. I’m happy when I’m with Eve. I want to live with Leon and Liv forever.”
“I promised Grandpa I’d protect you forever.”
Why are the siblings I’m not even blood-related to saying stuff like this?
“You were mine from the very beginning.”
“I tried everything to get it all back. Possession, reincarnation, necromancy, whatever it took to bring you back.”
Why are all these past-life ties tangled up around me like this?!
I just want to take back what’s mine and live in luxury like a rich, carefree slacker!
