Weird top two spot 25/50

[argo4hustler]

This hand was occured within the first 10 minutes of sitting down. I have rose and took down a couple blinds but I havent seen a flop/ played a pot yet. Any advice on any street is much appreciated.

UTG and BB both winning regs. I figured that any street I bet I will only be looked up by JJ from the bb or utg, or possibly kk from the bb; and TT and QQ will pass. This hand may be very standard, I just felt unsure if I am missing some value here. Does anyone like a raise on the river here?
