Black Hand, I Need to Live Too!

I regained my memories of my previous life after being hit by a candlestick swung by my biological older brother, the crown prince.

This is a world inside a book, and I’m Lizbet, a princess who doesn’t even appear in the original story?

I only have two months left until the day I die.

I can’t die like this!

Following the suspicious helper’s words, I climbed the tower and managed to swallow the blue jewel(?) that would save my life...

“You tried to covet my heart without permission, so you should be prepared to pay the price, shouldn’t you?”

Of all things, it turned out to be the magic tower, and the jewel was the black-bellied mastermind’s heart!

I need to do my best to restore my depleted divine power,

I need to take revenge on the royal family that only ever used me,

and I need to take back the crown prince’s position and restore the broken empire!

“In that case, could you lend me your heart a little longer…?”
