Edit2: ok I got it, deliver the cave fruit to the fat dude in the inn and choose the second dialogue.
Afterwards talk to the book pervert and the road west opens
Can someone please explain this part in more detail? I still can't open up the western road. Every time I try to go further west a pop up message appears with the girl and her companion. I've only got the inn keeper with an ! point and the book shelf in my room and am not sure what to do?
EDIT!
You need to make an item using the book call a Guraibaa. Using the book in front of the dog, under special key items.
Then approach the cave with the rock blocking it, and head back to town to have a h scene with the blue hair man
located north on the park bench. There will be one more scene with the gentlemen to the north and a magic bubble
will appear in your house and the ! point by the book case will disappear. You can now fast travel to the western area.
