I Became the Beast's Captive

I hate myself for feeling pity for you.
You, the king of the enemy nation who ruined my life and made me a prisoner.
“Rozenne, did you think I wouldn’t know if you deceived me?”
On the day of my wedding with my fiancé, I was dragged away as a prisoner of a powerful nation.
To the land of barbarians, Wolfhard.
But I wasn’t completely without a plan.
Cynthia, a court maid who switched appearances with me, became my double.
Cynthia became me, and I became Cynthia and went to Wolfhard.
However,
“Did you bring the right woman?”
The beast who wanted me as a prisoner shows interest in me.
Not in Cynthia disguised as me, but in me disguised as Cynthia.
Why?
Cynthia’s appearance is exactly the same as mine.
You wanted Rozenne.
Then you should like Cynthia who became Rozenne, so why are you obsessed with me who looks like Cynthia?
Then on a night with a full moon….
Cynthia, who had gone to the beast’s basement, came running back in terror.
“Lady Rozenne! Something’s wrong with Paikan!”
Because of the frightened Cynthia, I went to the basement in her place.
The growling sound echoing in the basement was clearly not human.
My heart pounded wildly, and just as I thought I should go back up,
Two irises suddenly gleamed in the darkness.
And something unidentifiable dragged me down below the basement.
