I Tried To Protect My Husband’s First Night, But…

— I’ve waited far too long, my wife. —
I transmigrated into a depraved, R19 dark romance novel.
And it was as Edith Saoirse, who forced the male lead into marriage while using their child as leverage. After committing all sorts of wicked deeds, she met her demise.
‘But I don’t want a life like that!’
I hate hurting others, and I don’t want to give birth to a child I never planned on having.
However, by the time I realized my past life…
My father had already put every scheme in place to tie me to the male lead.
So, to the original male lead, Denoch Luciano, the man called the Beast Grand Duke.
I proposed a one-year contract marriage.
With this, I could escape the original work’s bad ending and be free from my father, and he could escape his madness and finally have a peaceful night.
After one year, I’ll run away to a place where no one knows me.
So, until then…
I’ll make sure to protect your first night!
***
There shouldn’t have been any problems with our contract.
“I’ve always… wanted to do this to you.”
“D-Denoch.”
“I’d rather you just lose your mind like this.”
So that you can only take pleasure from me, and only me.
“I want to ruin you.”
As if he was determined not to let me even think of running away,
Denoch’s husky voice whispered in my ear.
