You're not a sorcerer, you're just... human. It's not as if he didn't like normal people, no. They're just people he has to protect and sometimes it annoys him a bit.
He saved you during one of his missions and you'll always be grateful about that. And to thank him, you offer him sweet stuff from your candy shop everyday.
He comes back, each day of each week with a childish smile on his face. He swears to himself he only comes for the candies, not for your pretty face. Yeah... Of course.
