It's cuz normal people and him self saw his self as normal except for mc(the top) who can't see his face

It said in one of the earlier chapters that the extrovert is able to see curses, they show up as black on the body part. The introvert is always chasing paranormal stuff that he’s constantly being cursed, but in some chapters it changes on thickness. So, he is human just heavily cursed :) everyone sees him without the black marks
i cant believe i just missed this details
he didn't think himself as paranormal at all
