TL Soseol Sok Sinyeo-ga Doeeotseumnida

I was bored and read a TL (teen's love) novel with lots of sexual scenes and ended up reincarnating into it as a maid that gets executed, and quickly at that! My goal, of course, is survival... but the situation keeps getting twisted.

"I have no intention of sharing something I like with my brother."
I was so surprised that I harshly bit my lip.
"Don't become the Duchess. The rumors that my younger brother has fallen for a rabbit have reached even my ears."
"Your Majesty! No, that's..."
He rubbed my bleeding lips. Then he nonchalantly licked the bloodied finger. It was just his finger that touched me, but I somehow felt nervous.

Your Majesty, please save me. I don't want to be execute...
