WSEX hand raise for value with river two pair?

[uminchu]

Villain in this hand is crazy, he c bet three bet bluffs, has tripple barrel donk bet into me when i raise with A8s and flop the ace and call down to see 84s no pair no draw rarely folds to any kind of raise especially possible steals. WSEX 6 max 50 NL table I raise A5o in CO to 2 bucks, Button calls, SB (villain calls) as down BB. Flop A34 two spades (A and 4), i bet 5 dollars into 8 dollar pot, button folds, SB calls, BB folds

Turn K sb checks, i check

river 5

villain leads into me for pot, i obviously call as this villain is crazy and i cant really see him calling on flop with just a 2, but who raises? my thinking was that there arent many hands that can call a raise that i beat

Standard just call?
