I Picked up a Black Panther and Became a Duchess

I was reincarnated as an extra who gets beheaded by the male lead, simply for being associated with a group of villainesses.
Thankfully, I was born into a minor family with no connection to the main characters.
As long as I avoided getting involved with the villainesses, I could survive.
But then—
“Emilina Klein?”
The male lead suddenly came to see me, even though I had been living as quietly as if I were dead. His unexpected arrival made me think I might die again.
“Didn’t you once pick up a black cat?”
Instead of holding a sword to my neck, I heard the male lead’s gentle voice. And even more shocking was what came next.
“Will you marry me?”
“W-What did you just say?”
“I asked if you would marry me.”
As I stammered in disbelief, the male lead added another sentence with a satisfied look on his face.
“You only need to bring yourself.”
In his golden eyes, a ravenous desire flickered, like a predator on the verge of capturing its prey.
Um, excuse me?
We just met, and you’re talking about marriage?
