I’m calling it

Ngl Guwon has me intrigued. He doesn’t know basic social etiquette, doesn’t have elementary teaching, and generally lacks healthy socialization. Like kissing the guy, saying things to the ML without thinking of its implications, etc.
But can successfully run a town in the midst of an apocalypse. He knows of social hierarchy, the importance of the next generation and how to pass the torch to them, and other primal instincts to survive. Something tells me he’s not human, maybe even a mutation of the maggots of sort. At the very least, if not that, he was definitely isolated or possibly controlled in some sort of way.
