Unique in the best way
First, of all, I really enjoyed this story even though it took a while to read all the chapters. This story is really different and unique and I think it's really interesting.
Read the story now
As for the characters I really enjoy Ace and Theo. I think they're very good and characters and you can sense the depth in them. I also need to compliment your writing, it is absolutely amazing and I wish I could write as good as you.
Some things I things you could think about is maybe explaining the world a little more because I'm having a little bit of a hard time grasping where this story is set, is it a fantasy world? Is it set in the future?... Maybe take a little more time explaining the world to make sure the reader knows where the story is set. In my opinion, you could make the chapters a little shorter but that just a personal preference some people love long chapters.
Overall I really enjoy your story and I'm so excited to keep reading.
