his small bets look like 64 to me or 68 no other draws out there. some fishes also play sets like that. they bet small till river and then they fire a huge bet. i think u can find a fold here even u showed weakness on the flop by misclicking. by how its played he canstill think your turn raise was a bluff and he gets you to fold when he fires a big river bet.
Still its a fold for me.
