You're folding the flop because if you do anything else you're putting in a good amount of money against an UTG who can play perfectly against you.

TPTK is the nuts on boards like this usually because usually your range includes bluffs which means that UTG has to play many hands worse than TPTK or else you'll own him. Here, you obv can't be bluffing because the side pot is dry, and you can't have a draw except a big combo draw because you're not getting odds and obv you have no implied odds with the dry side pot. So UTG has a really easy fold with KJ.

Since nobody folds better than TPTK ever, UTG won't drop any hands that beat you either. So he's playing totally perfectly against you, and you're committing a lot of money getting [censored] pot odds.
