I feel like when you know a worlds future and then it suddenly begins to change, that could be terrifying. I hope it leans into it because that last scene where she doesnt know what will happen/do if people diverge from the story seems to imply that she is scared. It would be far more interesting as well. Also its not like she doesnt know he likes her, she just assumes he eventually end up liking the other girl more and is trying to save herself from the pain prematurely. Case and point being how she specifies as a friend in their conversation.
