This was a nice read! There was only a couple of things I could complain about.
The writing needs some work too, for example; There are a couple of plot holes in the story, there are quite a few grammar and spelling errors, and the pacing of their relationship felt rushed as well. And we never got Charles' explanation on why he had joined the rebellion.
I liked the characters though and I liked the premise of the story (kinda want to see an epilogue for these 2). The art was also nice!
Great job!
