The original world protagonist somehow has passive mind control. Anyone that's not a noble above like a Count does his bidding and goes crazy to help him and I mean everyone from s*aves to servants to Barons. And since he doesn't know it's passed off as him being righteous.

Theres characters that aren't affected but somehow they can't do anything including the royal family. They just watch because he's not actively doing anything (in terms of mind control, there's a whole lot of punishable stuff he does and gets away it, but I digress) and he can't be persecuted so the whole novel is just dealing with that stalker weirdo that follows FMC and ignores all logic to do whatever he wants and a ton of NPCs supporting him while MC has to deal with it for no reason.

It's one of the most frustrating things I've ever read and I'm not gonna continue reading it in the hopes the maybe someday somehow they could find a way to stop it. The premise of the novel is that the original protagonist was chosen by that damn world tree so it's most probably the World Tree that is the reason wich means that bs is gonna drag for the rest of the story and if somehow it didn't then it'd be a different story making the whole disgustingly frustrating premise useless.
