NL100 - Bottom set fold

[mack848]

I can count the number of times I have folded a set on the flop on one hand. I know the flop is drawy, but I just couldn't see this guy 4betting the flop with anything other than a made hand or a monster draw. Is this fold OK?

Villain is 21/10/1.3 after 200 hands
