i doubt he has a lone king. most tightish/decent players OOP will not raise this turn. even if he has a QKish hand, if he decides to raise, he coudl easily talk himself into calling a push here on this board.

I don't see why he'd ever take a raise/fold here line besides a bluff (seems unlikely), but I can see him checking a ton of rivers.

any two pair hand with a king seems possible or even a flopped two pair/lower str8/same hand.

maybe im weighting his range too heavily towards bigger hands but given the description, in my experience vs. an aggro (which i believe u are) they arent raise foldign a real hand here.

correct me if im wrong
