I Will Become the Troublemaker of the Villainous Duke’s Family

So… the problem is that she became too nice?
“Our daughter suddenly became kind.”
“She’s helping the maids, donating to the church…”
“She even joined a charity organization!”
Looking at the tearful Duke and Duchess of Tenebris, the counselor thought:
‘So… the problem is that their daughter became too kind?’
* * *
I possessed the body of Leriel Tenebris, the only heir of the empire’s worst villainous duke family, a girl known as the most wicked woman in history.
“The villain family that got wiped out because a saint put a curse on them? Even distant relatives were all executed?”
To survive, I have to cut ties with this crazy family…
But the more I rebel, the more they’re pleased, saying I’m growing up to be a perfect villain.
This won’t do!
I’ll show them I’m not fit for the Tenebris name by doing as many good deeds as possible!
“Who are these skinny kids? Go buy out the best bakery—bring everything!”
“I should donate some money. Let’s start with just 1 million Merks.”
“Which town got attacked by monsters? I’ll go myself. Prepare a volunteer trip.”
As I desperately try to survive by doing good deeds and being a perfect daughter…
Even the crown prince, Peril, whom I was forced to get engaged to by blackmail, starts chasing after me.
“Leriel Tenebris. I will never believe that you’ve turned kind.”
To survive this chaos,
I’ll become the troublemaker of the villainous duke’s family!
