Who are the main character in Romeo and Juliet?

Romeo and Juliet, obviously, are the main characters.

Other characters essential to the story are Friar Lawrence, Mercutio, Tybalt and Capulet. Not Benvolio, or even the Nurse.

Here's the story as compact as you can get it: Romeo meets Juliet at a party. Tybalt objects to his presence but is prevented from doing anything at that time. Romeo and Juliet pledge their love to each other and Friar Lawrence marries them secretly. Later, Tybalt finds Romeo with Mercutio. Romeo is unwilling to fight Tybalt and Mercutio takes the mickey for him. Romeo is incensed and kills Tybalt. He then (or shortly thereafter) flees as he is wanted by the law. Capulet insists that Juliet should marry another man, and she seeks the friar's advice. She fakes her death, and Romeo returns to complete the suicide scene at the end.
