In my mind the MC actually caused all this. He’s gaslighting himself into thinking Guwon was the killer and it was him all along. Like he was a teacher but never said what kind. He was really a science teacher doing experiments and created Guwon and these other zombies and the first victim was his own father… after his experiments got out of control the guilt made him suppress his memory of his part in all this.
