I Saw the Future With the Killer Grand Duke

Pretending to be good, pretending to be weak, pretending to be pitiable.
I possessed the body of Gabriella Nashiret, a villainess who managed a three-piece anger combo on the reader.
And to escape my predestined death, I requested a contract marriage with Ernst Eckes, the Grand Duke of the North.
So, far from the setting of the original work, the three years I spent with my husband were very sweet.
Even so, it all ended with my death.
“If you and I are given another life, I hope we’ll meet again.”
But when I woke up again, I found out that I was the daughter of the man who killed me.
Do I even have to have an arranged marriage with my ex-husband?
