QJs small blind hand

[Blake Lovely]

QJ's small blind full 10 handed tight 20-40 game.

everyone folds to middle position fairly tight/very aggressive player who raises. everyone folds to small blind. calls the raise (?).
BB folds. heads up

flop comes 6 J 7 two suits. bet - mp raises, call.

turn is a offsuit 2, check call.

river is an ace, check call.

Mostly wondering if folding preflop is the best play. Seems overly tight, but might be proper. comments?

i feel like i'm playing bad when i call here...i like to fold QJs here but if some guy is really out of line in pre-flop raising i might want to defend with a call or a reraise.

Do you think this guy raises the flop and bets the turn with KQ, 99, or 88? If not you can probably fold this river.
