Villain goes all-in. WTF?!

I know some of you shove the turn, but what hand is folding that has you beat? And what hand is calling that you beat? Is this ok reasoning? Also he bet so small and I had a huge draw I figured I'd just take the value.
I wasn't sure where I was at his range here seemed pretty narrow. He had exactly KJ or nothing.
