Turned set facing massive reraise

Villain is a decent TAG for this level. Haven't seen anything weird from him.

I know we're pretty deep but I think flat calling here is just too strong and any hand that calls a reraise in this spot will probably call a shove y/n?

CO($72.79)
Button ($5)
SB ($31.87)
BB ($60.94) [Hero]
UTG ($8.50)

Hero is BB with 2:club:, 2:heart:
Preflop: (4 players, $0)
CO calls $0.20, Button calls $0.20, BB calls $0.10, Hero checks

Flop: 9:heart:, 5:spade:, A:club: (4 players, $0.5)
BB checks, Hero checks, CO bets $0.20, Button calls $0.20, BB folds, Hero calls $0.20 [I know, probably a shite call]

Turn: 2:spade: (3 players, $1.1)
Hero bets $0.80, CO folds, Button calls $0.80 and raises $6.40, Hero?

don't be scared your hand is very strong. Technically you have the 4th nuts. In reality though 2 of the hands that beat you are unlikely. Surely a decent tag would raise with pocket aces or 9s so we i would really only worry about pocket 5s. Sure there is the chance that they decided to get cute with pocket aces but there is still noway i ever fold this hand

Weird. If I ever wanted to be careful with a set, it's here. 43 is a possibility, albeit slight, as is a slowplayed set of 5's, maybe 9's, or A2. I don't see a lot else. I probably flat call this raise and re-evaluate river. Maybe block bet, but prob c/c. It's hard to imagine folding, but the guy's clearing trying to build a pot here.

Hero calls, and button shows 3,4 of spades.

call not close
