Anyone bitching that "this could all be solved if they would just talk it out! How annoying!" Is free to drop this at any time.
It isn't as simple as "they can just talk out the misunderstandings". She knows the original story, so she knows how the OG Nocton broke the OG Valrose mentally and killed her off. Now she knows that he's been trying to control her all this time, failing, but trying all the same. Anything he says to her could be a lie.
There's also a lot of "aren't they friends? Doesn't he treat her as a friend? Why can't she just trust him?"
Maybe because he never did treat her as a friend? Regardless of how he actually thinks and feels about her, he never actually treated her as anything more than a nuisance. It was mostly to drive her away at first, then to protect her from his family, but he still treated her badly while she was trying to be friends. I swear none of you actually read the story, because this gets talked about within the first 5 chapters.
So, he has never treated her as a friend, he's been controlling nearly everyone with black magic at one point or another, has tried to use it on her as well, and she knows the original story and thus doesn't trust him anymore, which she shouldn't. He can't just say "Valrose, I love you! Be mine! *hug hug kiss kiss*" and everything end with a happy ever after. First, she'll think he's trying to control her again. Second, she doesn't believe he's ever even looked at her as a friend, so there's no way she's going to believe he's in love with her. Lastly, if she did get with him anyway, her friends (and they are, whether you like it or not) would try to free her. You can bitch about that girls dreams being wrong, but they haven't been. The things that haven't happened are because the MC here has interfered, so they didn't occur. We know the most recent one is true because of the previous chapters where Noctons mother is featured. It isn't that hard to use your heads and think guys, so y'all should try it.
Anyone calling her stupid, a bad friend, or anything else like that needs to take a reading comprehension class and drop this story, because you obviously don't actually understand what's going on and why it's happening at all.
End rant. Have a nice day.
