Reraised pot with Grimms favorite(or maybe least favorite) hand

[THE_NER]

villian is big work from full tilt. Hes like 27/23/2.5 and seems kind of good, but i havent really seen anything out of him. I have been playing like 24/21/3 but havent shown down anything and have been running cold as ice

Effective stacks are 620

villian raises on the co to 21 and i raise to 80 with AsQc out of the sb

flop=Ah9d5d

I lead for 140 and he calls

turn=8h

I check and he goes all in for 406 into a pot of 446

Is this Ak or a set everytime?
