Can anyone explain to me what that plan of the mc was ?like I dont get it ??

Her plan was to write a shitty/unfitting ending to her fanfic so that the blonde guy(who has tried to kill her bcs her existence causes an error to his heart thing) is prompted to meet up with the author(her). He is so invested in the story that he can’t and won’t tolerate the ending, but he can’t just rewrite it himself. So thats how she gets leverage to make him stop trying to kill her. She rewrites the ending so it’s suitable to his expectations/ or continues the story(i think both but i can’t remember) = he won’t try to fix the heart error aka kill her

Thank you very much
