Which lines best set a romantic mood in Act II, scene ii of Romeo and Juliet?

What man art thou, that, thus be-screen’d in night,
So stumblest on my counsel?
How cam’st thou hither, tell me, and wherefore?
The orchard walls are high and hard to climb,
But, soft! what light through yonder window breaks?
It is the east, and Juliet is the sun!
At what o’clock to-morrow
Shall I send to thee?
