The Villain Family’s New Daughter-In-Law

Luciel is a [Crystal Fairy].
Someone who can create jewelry when she feels strong emotions.
She died after being exploited and returned to the past!
‘This time, I will never live like that.’
In order to avoid the worst future possible, she even proposed a contract marriage to the Empire’s top villain family.
But something became weird. The start of this relationship was definitely temporary.
“How about becoming my daughter instead of a daughter-in-law?”
“I always wish I had a granddaughter, this is just perfect.”
“When I grow up, I will marry my sister-in-law.”
How come they are doing this to me when they were said to be villians?
Besides…
“Whether it’s a jewel or a flower, it doesn’t matter to me what you make.”
The reaper of Bellstein.
The man who was in ruins in her past life said so with a fresh smile on his young face.
“If you get out of my sight, I’ll chase you to the end, Luciel.”
