Don't worry! My king thout I was food for the first 18 months I had him! He is now the softest most inquisitive snake. Kings just require gentle persistence - you may have to take a few bites and muskings, but its better to get it out of his system when he's younger, he will learn you aren't a threat after a while - they are a bit more hard work than a corn, but then they have more chartacter to them. Good luck!
