It looks like a pretty safe flop there is a straight draw but for your opponnet to have that they would have had to min raise UTG with A2 or 56 is this likely ? That said I would never give a player a free card if all I'm holding is top pair, it is to weak. I would only give free cards if I am holding top 2 pair or better.

I don't hate a free card here...
