he makes a plan to marry juliet
He is a bold and decisive person. He doesn't shilly-shally about.
"Then I defy you, stars!" He immediately makes plans to go to Verona even at peril of his life.

Juliet sent the nurse to see Romeo about the wedding plans at 9 o'clock in the morning.
Juliet says that she will not be satisfied until Romeo is dead, and she wants to mix the poison that her mother will send him.
In "Romeo and Juliet," Romeo and Juliet are the only ones who know the details of their conversation on the balcony. Romeo overhears Juliet speaking her thoughts aloud, and the two lovers share a private exchange where they declare their love for each other and make plans to be together.
She acted as a messenger between them. She helped them make their plans by carrying their messages to each other
According to my copy of the play, line 117 of Act 2 Scene 2 (the balcony scene) is "I have no joy of this contract tonight" which has nothing to do with making any plans.
She runs away and pretends to be dead but Romeo believes it and kills him self too. :(
Romeo is comforted by Friar Laurence, who advises him to be grateful for being alive and begins to make plans for Romeo and Juliet's future together. The Friar provides Romeo with hope and a sense of purpose, reminding him that there may be a way to overcome the obstacles they face.
It's mostly about Romeo falling in love with Juliet however knowing that he has no chance with her and vise versa with Juliet. They make plans to see each other at the church and elope.
Juliet says that if he is serious and plans to marry her, she will send a messenger to meet him at nine o'clock. This messenger will be the Nurse, of course. Romeo will then reveal whatever wedding plans he's made to her. Have you noticed how little wedding planning Juliet does in the play?
