Juliet appears on the balcony. Romeo stops, awestruck.
The most beautiful story to ever exist! Romeo and Juliet, ah! makes me swoon.
So he's staring at her while she's sitting alone. On a Balcony. That's not cute. It's called STALKING
NO. This scene shows us the contrast between day and night, a.k.a, Juliet and Rosaline. It's riddled with metaphors and beautiful comparisons.
the purpose of the scene in the entire play is to show that Romeo is no longer in love with Rosaline
Notice how he compares her to the sun. Although the moon, who is Rosaline, is beautiful while it lasts, when the sun comes, it disappears. The sun Juliet, is the centre of his universe. Nothing and no one can compare to her.
