Our classic idea of romantic love is embodied in Romeo and Juliet. Shakespeare presents this as a force of nature, so strong that it transcends societal conventions. This idea is established in the play’s prologue with the line “a pair of star-cross'd lovers take their life.”
Perhaps Romeo and Juliet's love is fate - there love is given cosmic significance which can therefore overturn the social boundaries of “fair Verona.” Their love is disallowed by the Capulet and Montague households, and Juliet is to marry Paris – Yet, they inevitably find themselves drawn together.
