Uh it’s not Taejoon (black haired) who controls the hands but Yeonwoo (the author). Assuming that he has been “eaten” by the mirrors. I think the motive behind is to make Taejoon give in or break the same way Yeonwoo did who lets the supernatural control him, or rely on Yeonwoo more. Either way this is just my conclusion. It’s easy to break people down when they’re helpless, like how Taejoon is beginning to lose friends and whatnot.
That means the “ghosts” or illusions can actually harm people,,,, gosh. Poltergeist I tell ya,,,,
