Bottom set facing a river C/R from Reg - 100NL

Villain is 23/18/3.7 over 621 hands. Fairly aggressive regular.
This is probably my 2nd or 3rd orbit at most after sitting down at this table. The only hand I played against him so far was I had KQs from BB, he PFR from BU with QT, flop came Q high I C/Red flop, bet 1/2ish both turn and river and he called me down, resulting with him losing the hand.

What about my bet sizing on this hand? Should I have B/F a smaller amount on the river? Is that even an option given recent history?

Button ($138.90)
SB ($98.10)
BB ($265.50)
UTG ($100)

Preflop: Hero is MP with ,
1 fold, Hero bets $3, 1 fold, Button calls $3, 1 fold, BB calls $2

Flop: ($9.50) , , (3 players)
BB checks, Hero bets $6.50, 1 fold, BB calls $6.50

Turn: ($22.50) (2 players)
BB checks, Hero bets $14, BB calls $14

River: ($50.50) (2 players)
BB checks, Hero bets $42.50, BB raises to $242 (All-In)

Would he play 78 like this? A7/A3/A8? Such a nut line in less aggressive games. I think you see a backdoor flush a fair clip of the time. Something like T9 clubs or 98 clubs.

On the river what you putting him on when you size your bet?

you played it fine now fold
