I've played a villain with similar stats once. Replace the K on the board with an A.

Same exact action, pretty much identical bet sizes, and 250BBs deep instead of 300BBs.

I called, he bet 50% on the river and turned over A7 (in your case K7).

Obviously we're talking about 2 different hands and a different villain (most likely heh), but I don't think it's impossible for to him to have K7 here. His VPIP is nearly 50.

I don't think AK is good here, but I'll repeat what Nick said. Wtf are we calling with then if we fold AK here?

I really don't like this spot when you're this deep because very little went into the pot preflop and on the flop compared to the turn/river.
