10-20 KK, weaktight, or intelligently cautious?

[Acesover8s]

10-20 game.

UTG limps. Another limper, I raise with KsKh. BB calls. UTG 3-bets. Limper between mucks. I cap, both call.

Flop is AdJd5d. Pretty much the worst flop I could imagine. BB checks, UTG bets, I raise. BB folds. BB calls. Turn is the Kd.

So now I have a set, but any diamond beats me, and who knows if my set is good. He checks, I check back.

River is the 4s. He checks. I want to bet, but chicken out instead. He shows AsQc, and I take it down.

Who plays this differently, and who calls me a little girl right to my face after this hand?

Thanks,
