The problem with the stepfather was resolved a bit to fast for me:
Hijiri: i don't want
Stepfather: okay i don't to see yr face again
End.

It was kinda more complex that that. 1. Hijiri said he wouldn't do it. 2. There was the insurance money (so the excuse about Hijiri owing money disappeared). 3. There's the illegality of the stepfather actions. 4. What's more, Nobuo was determined to help Hijiri. So the stepfather realized his "power" over Hijiri vanished and decided to "set him free". He knew he was gonna go under lots of (legal) problems otherwise.
It isn't finished
I hope not, it's so good that I want to see more.
