flush with river board pair passive player

Hi all!

You wrote not at all of course if passive player start raise always has a monster hand. River board pair i think not so many big bet call here only better hand than flush maybe K high flush. Can i re-raise here or not? Villain raise after i not put full house here but if i 3beted here villain will call worst hand than full house?
