What's Juliet's immediate reaction when she first sees Romeo in Shakespeare's play Romeo and Juliet?

I would say
that 's immediate reaction is best described as coy (a mixture of shy and inviting at the same
time). Whenfirst sees her, he takes her hand and then asks to kiss her. her first response,
"Good pilgrim, you do wrong your hand too much," shows that she is surprised by this
gesture. She is politely telling him that taking her hand and asking for a kiss is an act of
devotion, that he does not need to apologize for, even though they have just met.

As they continue this playful banter, he again suggests a kiss:

"O, then, dear saint, let lips do what hands do.

They pray; grant thou,
lest faith turn to despair."

Juliet is too well-mannered to tell Romeo he can kiss
her, but she does not discourage him from doing so. After their kiss, Juliet tells him,
"You kiss by th' book," which means he is a good kisser. This line is a good example
of how Juliet is definitely inviting Romeo's continued advances.

Soon after
the two are seperated and Juliet learns that he is a Montague. Her famous aside shows her
immediate reaction to this news:

"My only love sprung from my only hate!

Too early seen unknown, and known too late! Prodigious birth of love it is to me, That
I must love a loath¨d enemy." This is the line that demonstrates love at first sight.
Though they have only spoken a few lines to each other and exchanged two kisses, she is already
hooked and doomed, which is clear from the line, "known too late!" He is the only boy
she has ever had such strong feelings for, but he is her family's "loathed" enemy.
