preflop:min-Raise with AA hoping someone would 3bet/squeeze.Didn't work out,3 people call.
flop:bet half the pot,all called.(sb last to action,also called.)
turn:got the Top set,but apparently,someone out of this 4 players holds flush.Sb shove,hero how?

I elected to call after several seconds tanking,hoping someone holds a set as well.Definitely this is a -ev sopt.But in my view,this is much like a typical Gambling Spot,by which i mean,it's hard to decide whether to fold or call cuz we have some equity here dispite someone might has a made hand(flush).And if two player have flush draw here,i get the pot odds like 26.5% equity,disappointly somewhat a bit above the ideal(20%)
multiway pot is complicated.I can't get the whole picture of what the other 3 players hold.

Anybody can see this situation clearly and give me some advice on what action to take OTT?Can you fold this top set,why or why not?Thanks!
