Like, I don't want to say anything too strong, as this is a very personal story based on a very real person's experiences, but dear God, that mother is just absolute trash. And even then, how is it that no teachers or anything got involved and helped out? What happened to the younger sister? Does Japan not have the courts intervene in these sorts of scenarios, or is this simply a case of some kids being let down at every stage by people who should have cared? Given what we know about the mc, it has some kind of proper resolution, but this is clearly not something to read if you don't want your faith inhumanity tested.
