hi, I'm Korean community member ^_______^;
-My grammer could be wrong 
=-----
first why did you want to c/r in that moment??
I think you should have to c-bet/ and you could read his hand
If BTN had rasied, his hand might be TT, 77, 55 (or KK AA, slowplaying on the flop)
and If he had just called, QQ might have be the bast hand-JJ,AT..
Anyway you decided c/r, but turn gave K
we have to consider - 'BTN has K or not and flush draw'
turn ceck-call -> inducing bluff and get vlue, (river c/f)
-i think he would ceck behinde
turn bet $2.75-$3> it means- protect QQ from 
and straightdraw,
In river- c/f
I think- turn c/f is fine,too (my choice) - I don't think BTN bluff in the 3-bet pot,
Against middlestack I think you can´t away your hand, so b/c turn or c/c seems both fine options
Going to c/r this board is sometimes fine, but since you´re generally c-betting with air I like also c-bet with overpairs and then maybe going to c/rai on blank turn card
If I´d c/c turn, I´d also c/c river letting him bluff with worse hands
