I’m Getting a Job As The Duke’s Wife

Second life.
Reincarnated as a silver-spoon noble with mysterious abilities, but treated as a devil by her parents and even had her family completely ruined under the charge of treason.
No way, I’m a s*ave?!
But, my life is something I carve out myself!
She negotiates with a man who came to subdue the s*ave trader and secures an invaluable job opportunity.
“Please hire me. I can provide you with the information you need, anytime and anywhere.”
“Alright, Evelyn. I’ll accept your terms.”
However, there was one problem—
“I plan to make you the beloved Duchess.”
“Pardon? What Duchess?”
***
Evelyn suddenly finds herself employed as the Duke’s wife.
During the two-year contract period, she has three missions to accomplish—
First, win over the King, who dislikes her because of her lowly origins.
“You adorable thing, don’t leave my side.”
Second, melt the heart of her father-in-law, who resents his son.
“This child is not my daughter-in-law, but my daughter!”
Third, fend off the villainess who is determined to steal her husband.
“Evelyn, when I see someone as naïve as you, I just want to crush them.”
Will Evelyn be able to complete all her missions and safely retire?
