Miranda is introduced to Ferdinand in Act I scene II of Shakespeare's The Tempest. Upon seeing Ferdinand, Miranda procalims, "I might call him / A thing divine, for nothing natural / I ever saw so noble" (I.ii.419-421). She soon after asserts that "There's nothing ill can dwell in such a temple. / If the ill spirit have so fair a house, / Good things will strive to dwell with't" (I.ii.457-459). From these lines we know that Miranda is infatuated with Ferdinand and desires to be with him. She states that "I have no ambition / To see a goodlier man" (I.ii.483-484).
Therefore, if you are to take on the characterization of Miranda and write your thoughts at Ferdinand's proclamation that he loves, prizes, and honors you, you would undoubtedly be overjoyed with Ferdinand's vow. Certainly, you would return his love and promise to also love, prize and honor Ferdinand above all other men.
