Help! IDK which route i'm on in Kamidori

[EroJiji24]

Before I say anything alse, I am really forgetful, okay?

I read that the decision for route's happen at Chapter 3
I'm already at Chapter 4 and I don't remember seeing the scenes described for deciding the route (Probably I forgot)
Right now I'm at the scene where Serawi brings Wil to Reyshiamel.
I don't want to repeat a lot of stuff so can I have some tips on when I should save? or what I shouldn't do?
Note: I saved at the start of every chapter but I think I am forgetting something

Oh and if I am posting this in the wrong place, please tell me. I'm new here. :D
