In the book, the two become connected again after John Ambrose gets Lara Jean’s letter. They then become pen pals, and Lara Jean wonders if she made a mistake in being with Peter. But, based on the trailer, the plot of their relationship will be quite different from the books.
“I promise, I am not going to break your heart,” Peter says in the trailer, and Lara Jean says the same thing back. But, based on what is hinted around in the rest of the teaser, that’s not exactly going to be the case.
