to be fair, Guwon does not have sympathy for humans and like what was mentioned in the earlier chapter, Guwon treats humans like his pawn. Honestly ive already noticed he was a super red black flag when he vomitted and praised himself in the mirror after kissing the MC
I noticed he was a red flag because the whole town was scared of him lol. but yes, I understand that he doesn't have common human feelings, but as another comment said, he usually asks what the person can do for the city first, he doesn't just go around killing (unless he thought MC's dad was a zombie)
Is this memory really true? I've been defending Guwon being a red flag since day 1, but it doesn't make much sense that he killed MC's father out of nowhere. I guess we'll find out more since he said that MC didn't know "the whole story"
