Top pair top kicker would you call the river bet on a ugly board

Villains 2 times pot lead is really strange on the river. Indeed flush came, but didn't show any aggression on this point.
I would most likely fold. Flush is possible and even full house changes.

Normal I would try to represent a over pair on the flop with a Cbet and re-evaluete on further action.

Fair enough. Is indeed a decent change. Kind of loose call pre-flop without position to call for set value.
