I always wondering what is Kyosuke's job
The premise of the manga was that Hori's parents were never home, so she had to take care of her brother.
Now her father's constantly home, yet treated with disdain - was he, perhaps, fired, and unable to find a new job?
Also, Kyoko's psychopath first, masochist distant second. I mean, she's a teen and that can just be a sign of her age, but still.
