you should call it something drippy that doesn't make sense so more people will read it, like "shattered flowers for my beloved" or something

Gotta love prophesies, especially the ones that are really obscure, but maybe hint at what's to come? Well I love any story that is all adventure and fantasy because no matter what they never cease to entertain. You have an interesting concept that could use a little filling in in some places. I just have a few things to point out that I hope might help you with it, or at least I hope it does since you gave me a lot of good tips.

The first thing I want to point out is the section in the beginning. The part where she is crying in class after her friend de-friended her. The whole going into the past seems a little too abrupt, or something. It just felt out of place to start a story with and it seems odd that her long time friend seemingly randomnly decided she didn't want anything to do with her anymore. I guess it only works if you go into more depth later or add some more details in the beginning.

Your dialogue is interesting, but some of it feels a little too forced or something in a few places. You have a tendency to over use the "..." mid sentence. Sometimes it's alright to just say that the character paused or looked thoughtful for a moment before continuing. I liked the fact that they were talking about favorite colors while training, it was a nice touch.

Anyway, Aside from all that there were no gramatical errors that I could see or were bothered by-which is way better than I can do. Hats off to you. And this is setting up to be an interesting story. I hope you update it soon. :)
