this is not related wahtsoever with this chapter but i just remembered we saw a girl looking outside the window after she just woke up in the earlier chapters...did we get an explanation for who that might be? kana/koizumi? am i expecting to much?
So ... Still not hints as to who friend is, but I wonder if that is all there is to this story ... It seems like it would be anticlimactic for it to just end after that, maybe this haunted house will actually be haunted and make them go insane.
