A manga still can be good even it's not following the source. . . sometimes, it's actually better that way. Like in Yojou senki and assassins pride.
@8roku
It make a lot of sense, though i hope the author give us some hints before this revelation. I think his other flashback on the chapter before only shown his situation in the school, which he is being bullied.
Ok, we have another revelation. .
Turned out the parents are trash, it explains a lot. But since so many chapters ago we are always shown that it was a normal happy family and the brother is the problem. If the author going to pull this move, i think we need some sort of clue scattered around...
