Preflop limp not my favorite, but ok. I prefer raise here, then fold, then limp. The KJ is a hand that tends to lose money and is overplayed. It is weaker than it looks and that's even more important in a 5 way pot.

You hit top pair. Betting it on the flop makes sense, anything other than folding after that action this early is nuts. FOLD.
