I don't know how to feel about this hand. What should I do here?

What kinds of hands do I expect villan to show down here? I am representing a strong hand here, so when he raises me do I think he's supposed to have the nuts? Does he play a set this way? Pair and FD? Does this fit his betting? I'm lost here so help on any street is welcome.

Set is possible, but i think you are behind most of the time. Bluff-shove against 2 people who like their hands when the flush hits ? I don´t think so.
