In the prologue, romeo and juliet are referred as "star-crossed lovers."How might this be foreshadowing?

The definition of star-crossed lovers is a couple who are in love or care deeply for each other, but for one reason or another cannot be together. The fact that the prologie of the play cites Romeo and Juliet's love for each other in this way foreshadows the fact that all will not end well for the couple..... and it does not.
