Peter and Lara Jean have trouble admitting their feelings toward each other, much like Elizabeth Bennett and Mr. Darcy in "Pride and Prejudice."
And if Peter valued his popularity more, it would be similar to the class difference that Elizabeth and Darcy face.
The 2005 adaptation of Jane Austen's novel, starring Keira Knightley and Matthew MacFadyen, is a great place to start if you're new to the story. But if you're looking for more, the 1995 miniseries with Jennifer Ehle and Colin Firth is a great option as well.
