I’m sorry. I thought I didn't write the scene where Aris drinks Nessie's blood ( If it's the part about forcing Aris to drink blood water, then is there no any branching in that part of the plot? ), and there is no green-haired girl in the game, so still can't understand which scene is this...
I think you mean Valien—her hair is brown and her clothes are mainly green. If my guess is right, you’ve reached the end of the current update on her route. The scene goes: “Aris tries to eat Bryant, but Nessie arrives in time and takes him away; when Aris wakes up, Valien is dissecting him.” Getting stuck here every time is normal—the game isn’t finished yet, and I’m still writing what comes next.
If this isn’t what happened, maybe try ask all the questions before the timer runs out during Nessie’s questions. If none of this helps, I’m not sure what else to do… maybe try a different route?...
