At an engagement party for him and the women his father wants him to wed, Romeo takes off on his flying horse. As he flies around the skies of Neo Verona, he looks for Juliet. When he spots Juliet he fears he'll never be able to love her the way he wishes to when he sees her in the arms of another man, Tybalt. He gains his hope back though after he and Juliet speak to each other. At this meeting the two finally kiss!
One night Romeo goes to Juliet's home and declares his love for her and says he is willing to give up his name just to be with her.
