I can't see his friend's house?is this a bug or I should do something first to open his house?I forgot the name but it's his friend with white hair the brother of chiaki
if by open his house you mean go inside the house then you can't, if by open his house you mean go to the area near his house then you just need to progress the story. if you still can't then maybe it's a bug, so far the only bug i got is the money one
