Both of these are shadows. But maybe it varies from person to person, which one is the repulsive one and which one is the attractive one.
You brought up a good point Seraphim. Maybe it depends on the INFJ on which two types they feel repulsed and attracted to. But I definitely don't get that much along with ENFP's. At first I'm attracted to them(I've dated a couple of them) but after some weeks, I can't absolutely stand them. And don't get me wrong, I think they're great people but on a more personal relationship, it's very hard for me to form some kind of bond.
