Not a spoiler but i think Min Hyuk is the rat, and this guy who just choked the use to death is the politician who gets all the information

Mole, in the mafia society is used as a term to describe someone who is secretly a traitor/spy. But i don’t think people should use “rat” since it is considered offensive when referring to asian people, although, i’m sure the op did not intend to use it that way. Nonetheless, i hope it helped you for better understandingヾ(❀╹◡╹)ノ~
