Romeo is invited to a Capulet party and meets Juliet, "the most beautiful girl he's ever seen". They fall in love and kiss each other within hours of meeting.
The next morning, Romeo goes to Friar Lawrence and asks if he can marry them although they met like yesterday.
Romeo kills Tybalt because he kills Mercutio and then Prince Escalaus exiles him from Verona and he is banished into Mantua.
Both of the Capulets want Juliet to marry Paris but she loves Romeo and therefore she looks for an alternative. The Friar offers her a sleeping potion and she believes that is the best option for her.
Juliet is mistaken to be dead while she is sleeping and is buried. Romeo hears that she is dead and when he goes to the tomb he sees her unconscious and drinks the poison he bought from the apothecary. Juliet wakes up and sees Romeo dead and grabs Romeo's knife and kills herself. All of the blame is put on the Friar.
