The Duke’s Fake First Love

‘I’ll get revenge for my sister’s death.’

…That was the vow the female lead made at the beginning of the novel I found myself reincarnated into.
And I became the sister who gets murdered by her husband in the prologue!

Luckily, I managed to break off the engagement with my fiancé before the main story began, but then I got tangled up with the villainous hidden mastermind, the second male lead. The problem was, his first love wasn’t me; it was my older sister, the female lead.Still, I pretended to be her.

Because of that, he proposed to me, and I agreed to help him get revenge. But if he found out the truth, I’d be as good as dead, right…?
I planned to ask for a divorce once the revenge was over, but somehow, things just keep getting messier.

“You said before that as long as I stayed the duchess, you didn’t care what I did, right?”
“I did.”
“Then what about a divorce?”
“….”
“If I asked for a divorce right now, would you agree to it?”

Louis was silent for a moment.

“What do you think?”
“….”
“Do you really think I’d let you go that easily?”

…No, if I asked for a divorce, he’d probably kill me.
