This isn't bad, it just needed to cook a little bit longer. The character writing (mainly Ruying's) and worldbuilding needed more work, and there should've been less telling and more showing in a number of notable points, all of which would've served to give the story and what it was trying to do more depth. The end was nice and tied everything up well.
Lastly, after reading it, it's definitely not "the colonizer romance" some people claim it to be.
