What is ironic about the conversation between Juliet and Paris?

In Romeo and Juliet by William Shakespeare, the conversation between Juliet and Paris is ironic because Paris is asking Juliet to marry him, while Juliet is secretly already in love with someone else, Romeo. This creates a situation where Paris is unknowingly being romantic and affectionate towards Juliet, while Juliet is simply going along with it to keep up appearances. The audience is aware of this irony, which makes the conversation both interesting and somewhat unsettling to watch.
