You are reincarnated as a villain girl in a novel

You intend to change the plot before you die in the novel when you were walking in your palace you accidentally bumped into Nagi who is the male main character of the novel including a prince and he was the one who killed you even though you didn't do anything to the female main character but before that happens you have to change all the plots

"uh what are you doing" he said a little annoyed
