Mad Emperor’s Pet Sister

I became possessed in a R19 novel. My brother is the mad

Emperor of Aragon and I am the villainess and his half sister

who is also a supporting character, Isabella Belucci.

I thought I’d go back to the original world if I died, so I decided to go out of my way to rebel and get executed by Richard’s hands.

But…

“Why? Why did I not go back?!”

Instead, let’s change the goal this time and safely make Richard the emperor. Then, my path will be a happy ending!

…With that thought, I stole the heroine’s route.

“Does Sasha really think she’s my sister?”

Why does the male lead claim I’m not his sister?

“Sasha is like a snowflake.”

Is the second male lead also clinging to me?

The novel seems to began recognizing me as the heroine.
