The dramatic irony presented at the beginning of the story promotes curiosity and apprehension in the audience, which ends up generating suspense that motivates the audience to continue reading or watching the story until the end.
We can arrive at this answer because:
The prologue to "Romeo and J*" shows readers that the couple will tragically die at some point in the story.
This is an example of dramatic irony, as the author has allowed readers to know the information the characters don't know.
Therefore, the reader is curious and apprehensive about how the story will develop and how these deaths will happen.
This creates suspense about how the narrative will settle down through the story.
Furthermore, the dramatic irony causes strong sentimentalism in the reader towards the characters. What makes the reader stay until the end of the story with the hope that the characters are happy before their tragicendings.
