This looks horrible. I've grown a tolerance for abusive ML who might change eventually (?) but when the receiving end of that shit, the MC is an imbecile, I can't tolerate it at all. If this prologue didn't show him saying that the bastard is nice and if he didn't act like a fool, I wouldn't mind giving this a shot.
Reading this straight after "Palace of Bardo" makes this shit even worse since Palace of Bardo at least has an MC who isn't moved by the abusive bastard
