Extra-Changing Fate

"I want our engagement to be annulled,your highness"

I'm just a simple girl in the modern world who died and was reincarnated in the world of the fantasy romance novel that I once loved to read..... I'm not a Villainess nor the heroine, I'm just an extra who died at the beginning

and I plan to change that fate...and I plan to rewrite my own destiny, I don't want to remain the black sheep of the family,I want to be myself....I want to live however I want
