The option that you choose to run away with Koshiro is supposed to still be locked in this build ?
there is only one path for now since hiddenwall wants to make the routes meaningful
this is from the patreon just before the release for chapter 8:
Now I do want to say, Chapter 8 is kind of a bit ambitious for a one-man writer because there are a lot of paths to take. I planned it out this way to increase replayability and also to make your decisions feel more impactful on the story. Because of how Chapter 8 is turning out size and content wise, I have made the decision to release a more linear path for now otherwise I will be working on this one chapter for quite some time (and to be honest I do need to move on to another chapter because of fatigue). Of course I am not ignoring this chapter, I will be working on it from time to time and it will be finished up at a later date. Hopefully though you wont have to wait too long.
