No reads on Villain, he is new to the table for about 10 hands. 15/10/1.3

The only hands that pay me off are TT, JJ and QQ are getting more unlikely with his preflop line.
I had the strong suspection to be up against a set.
If i take strong draws into his range i guess iam still behind so i folded.
Is my line weak or standard?
Can i play it any different?
