In William Shakespeare's play, "Two Gentlemen of Verona" (1623 First Folio Edition), Julia says the following to Lucetta in Act 1, Scene 2: "They do not love that do not show their love." When Julia says this, she means that she doesn't believe Proteus loves her because he has said nothing about it (love).

Overall this play is concerned with factual situations. We see that after traveling to Milan, Valentine falls in love with the Duke’s daughter, Silvia. By chance or fate, Proteus also falls in love with her. He is forsaking the woman (Julia) he left behind in Verona. These two loyal friends (Valentine and Proteus) are transformed into enemies thanks to their fickle hearts.

A jealous Proteus betrays his friend’s plan to elope with Silvia to her father, and the Duke then banishes Valentine. Should Valentine and Proteus sacrifice their friendship for love, or can they somehow find a suitable compromise? Following the characters and their actions, this adventurous, romantic story has answers, along with hidden identities, comedy, a gang of gentlemen outlaws and even a double wedding.
