Hey! Sorry for the late rely.
There will be up to a certain point in the story where some changes in dialogue will change, but after that point is where the new content will take place. I am planning for a little scene after Marx and Aster leave to show them and the tribe, and I'm also going to show more of their relationship since I personally felt I could've shown them better.
Also thank you for noticing the bracelets. My friend(the artist helping me with the VN) put into my mind a characteristic Aster can have, like having matching bracelets to help bond them. His idea of this characteristic is all over the first CG. The colors were something I thought that could tell the reader without saying it. :)
