I Like the Obsessive Idiot Male Leads

I thought it was just a typical villainess possession story…
But what do I do if the male lead is an idiot?
I went to bed like usual, and when I woke up…
I had been possessed into a dark fantasy romance novel.
And not just any role—I was the obvious villainess who tries to break up the male and female leads and ends up getting killed.
The problem is… the male lead is my husband.
The bigger problem? My husband is an idiot.
And the biggest problem? He’s only pretending to be an idiot—and I have to act like I don’t know!
As if it wasn’t bad enough that I got stuck in the role of the dumbest woman in the empire, right after the male lead…
Now I’m stuck in this twisted, stressful mess.
Can I really survive in this novel?

“Bell-bell, who were those silly-looking guys from earlier?”
Pretending to be dumb while saying whatever he wants is one of Leon’s special talents.
“Guess who they were?”
“I don’t know!!!”
“Good job. You don’t need to know.”
Leon tilted his head and scratched it with a clueless look.
“Okay, Your Grace. It’s study time now. What should we learn today? Do you know this one? What’s 1 plus 1?”
“…3.”
He’s trying his best, our duke.
“Correct!!! You’re a genius, Your Grace. Do your best today too!!”
