It is not like he actively tries to go out of his way to hide it from his loved ones/friends. In time, his Identity will probably be revealed. I do understand not wanting to attract attention and revealing himself will attract attention. I do want his Identity to be revealed, but for now, it is fine that he wants it this way.
I understand your worry(or at least I think I do?), but I believe his Identity being concealed will be overcomplicated like that. Hopefully, I am right about that.
I do apologise for the long reply though(what with you not knowing the context currently).
