With that appearance it was totally a red flag. It was just the teisted personality what made you think it was green... And the CUTENESS.
tbh his appearance has nothing to do with it. he can still look like that and be a green flag, how he started acting is the problem
Sure. It is just my opinion that the author, the artist or both of them tried to play with the rude but soft appearance and the apparent innocent related to the world Guwon is trying to create, where he only wants people useful to him and he looks fine in front of death.
Honestly, maybe it is because I am approaching this story as if it was happening in real life, but if I have found a guy looking like him, I will be pretty scared... First because of the apocalypse that is happening and he is bigger than me and there are violent people out there, and after that because it is not common to find that kind of tattoo in somebody's skin.
As I have said, just my opinion taking the story out of its context xDDDDD
at the start of the story i called guwon and goofy guy and a green flag i take that back
