That other bitch who's always trying to bully the mc is just trying to be popular by always taunting him man people like her are annoying but man you gotta feel bad for the sister even if she did treat the mc like shit though he kinda deserved it...
Boy A didn't give detail information about what kind of 'harassment' the teacher did. People will think of a lot of possibilities regarding this. Actually, he's really idiotic. Just give the evidence to the police and ask them to not show any of it to the media.
