I remember reading this one bl (I think) where one of the characters are heavily abused by their father, to a point where his father forces his son to have no friends and started to punish his son for continuing to hang out with a certain friend his father didn't like. He also had one of the teachers watch over his son and report to him

I dont remember whatbits called, but thats what I remember the most.

Oh, also, his friends father confronted his father about the abuse and the son got in trouble again
