@Joonie's mom I'm thinking there's two different ghosts.
As for Na Jumin, I've met people IRL who acted a lot like him and had zero respect for boundaries. However, I do think he's being possessed by a third ghost who can transmit from person to person and thus take on their appearence. He seemed fine until he got that talisman thing back.
