TPTK small 4 bet pot

I don't think i'm chuffed with the 4 bet it would be pretty gross getting 5 bet. flop is lol. villain is 25/6 over solid sample 3b 2%... i def hate my 4 bet.
I assume FTR is all about folding the flop. although I cant see what beats me. suppose he can have sets but all are unlikely I don't see 2 pair callin the 4b pre or AA4455 for that matter which leaves AK and maybe AQ or some random spazzliture.

just realized we have history... on a different table; he limped UTG 88 I iso on button JTo and flopped a straight to stack his bottom set, happened a little earlier than this he might have remembered me.
I wasn't aware we had this history at the time of playing the hand.
