Romeo and Juliet
Juliet stands at her window lamenting about romeo because she is in love with him.
Romeo
"To whom will go the part of Romeo?" is better grammar.
She is happy to see him but scared because if he's caught he'll be killed.
Romeo goes to Capulet's house three times: first to go to the party, second to see if he can catch a glimpse of Juliet at her window, and third to get into her bedroom and have sex with her.
at first she doesn't, but he tells her he is there eventually
From what I remember. The first time he was waiting outside her window, he was actually hiding so she wouldn't see him. Then she finally saw him and then he climbed up the wall to get to her
Juliet, I guess.
She's looking for Romeo and because she wants to talk to Romeo about Juliet
Rosaline
