As someone said, the background characters are literal NPC's. I thought it was just some self-aware ironic humor by making them this generic, but no, the author genuinely has a fetish for this setting. Sad I guess
I've gotten impatient and read ahead in the raws, and all I can say is: steel yourself for the slowest of burns. 35 chapters later, they are still learning crucial parts of each other's backstory while tentatively building some mutual trust.
I love how they put the commoners as the villains here, no interest in reading anymore. Don't know why the author decided to put his dog water politics into this, just disgusting.
