 Shakespeare also uses sub @-@ plots to offer a clearer view of the actions of the main characters . For example , when the play begins , Romeo is in love with Rosaline , who has refused all of his advances . Romeo 's infatuation with her stands in obvious contrast to his later love for Juliet . This provides a comparison through which the audience can see the seriousness of Romeo and Juliet 's love and marriage . Paris ' love for Juliet also sets up a contrast between Juliet 's feelings for him and her feelings for Romeo . The formal language she uses around Paris , as well as the way she talks about him to her Nurse , show that her feelings clearly lie with Romeo . Beyond this , the sub @-@ plot of the Montague – Capulet feud <unk> the whole play , providing an atmosphere of hate that is the main contributor to the play 's tragic end .
