I can't start Morthra route because I completed Andre route, so when I want to ask her about the book she just gives me same text and then choise bathroom or library. My task in the phone says possible Informers - Andre and also nobody else is telling me anything related to it, please fix it or tell me what am I doing wrong.
P.S. This is my second time playing, and I remember that I completed Morthra's route as much as it was possible a year or something like that ago
