I don't know what's true anymore. In chapter 0, Guwon kills a maggot that wanted to hurt the teacher. In chapter 24, we learn that it was actually the Teacher's father. It's obvious that Guwon killed him. But Guwon couldn't know if the father was useful or not, because he didn't have the opportunity to talk to him. Guwon didn't kill people until he found out if they could be useful to him - he talked to the Teacher first, even though he wanted to kill him. The father's age didn't matter either, the Doctor and he were middle-aged. Maybe the father was infected, but he hid it from the teacher so as not to scare him. He came out as a human, came back as a maggot. Maybe the body was already a maggot, but the father's psyche remained and he wanted to take care of the Teacher like a father. And Guwon killed him because he was a maggot. I don't know. I really don't know how to interpret all this anymore
