UTG is putting you on AK (because that's what people do in FR games versus MP raisers) and he's telling you he wants to get the money in anyway. Can he limp/call preflop with something like
[5h] or
[4h], or is he a more standard "limp/call with pairs only" player?
I think his line is weird for a set though. There's a bunch of money going to be in the middle already if he check/calls: It'll be a $120ish pot with way less than a PSB left going to the turn. So why not flat call with a set, hoping you'll come along, instead of trying to push you out? But his line is even weirder for a draw, which will have way better pot equity if you come along, so again, why try to push you out?
While I try to puzzle this out I'm watching your avatar ... quite distracting.
No, I think he has a set, and just clicked "check" and then "minimum raise" because that's what people do in FR games when they flop sets.

Even if by some miracle you're ahead here against a lower FD, I still think the CO has a K of some sort almost all the time.
