She didn't know why either but it showed that even when she wasn't being active the story continued so she assumed she had to continue
yep it was a bit confusing. but after seeing her heroine POV. idk I just feel like she could of taken a different route. none of them would of suffered.
I mean there's def something going on. We see that everyone believed Kanna's lies very easily and after the story reached the "end" point, suddenly people started treating her differently and questioning what she said. From her POV, I think she felt that even the world itself was telling her that she was making the correct choices and she was too afraid to change things.
Not to mention, if she had deviated from the point, she would lose the advantage of foresight and wouldn't be able to know the future anymore. That's really scary considering you know some kind of magic must exist, otherwise she wouldn't have reincarnated. However, I think this story is a lot more thoughtful than other reincarnation stories because in most stories the heroine doesn't think about it too deeply and only has flimsy excuses to keep going with the orignal plot.
How odd I never understood why the reincarnated Heroine always wanna follow the original the story, in my opinion as long as there is no system of a god controlling people like puppets, I see the original completely useless, half the time the story don't be correct 50/50 it be wrong or right. just like this story the villainess wasn't a villainess at all. if they story wasn't following the correct way, Why did kanna try to put it back to the way it was? because the original story was already twisted. they always saying "We gonna die if we don't follow the original" but honestly nothing happens?? the roryal family believe a lie so easily but then did a whole 180 figuring out she lied? lol.
