Warning: Spoilers ahead for the movie and novel versions of "To All the Boys I've Loved Before."
"To All the Boys I've Loved Before" is an ideal teen rom-com.
Based on Jenny Han's best-selling book of the same name, the story follows Lara Jean Covey (Lana Condor), a teen girl who writes letters to boys she has loved. She's written five in her life but never mailed them, until one day, all of them get sent. With one of them being written for her sister's boyfriend, Josh (Israel Broussard), Covey pretends to date Peter Kavinsky (Noah Centineo) to show Josh that she doesn't love him.
There are some minor details that are different in the Netflix adaptation of the book, like the car Peter drives and who comes up with certain rules for the contract, but there are a few major changes the movie makes.
Here are nine of the biggest changes made in the movie, which premieres on Netflix Friday.
Josh and Margot fight before breaking up.

When Josh comes over for dinner in the movie, he surprises Margot with a plane ticket he bought to visit her in Scotland. Margot is visibly upset and the family knows it. They fight and break up later that night with Margot confronting him about the surprise purchase. Lara Jean overhears the argument from her window.
In the book, Margot breaks up with Josh so she doesn't have a boyfriend when she goes to the University of St. Andrews and then just tells Lara Jean the next morning.
Lara Jean and Peter have a different run-in outside of school.

In the movie, Lara Jean backs into Peter in the school parking lot as she and Kitty are going home. This is also the first time Kitty meets Peter, which is not the case in the book.
In the book, Lara Jean totals her car after rolling through a stop sign. Peter drives by and stops his car to see if she is all right. At this point, she's already called Josh to come pick her up, and he leaves to go to Gen's house.
The letter distribution happens much faster.

Josh starts walking toward the track, letter in hand, when Peter is confronting Lara Jean about the letter he received. When Lara Jean sees him, she launches herself towards Peter and kisses him on the track.
In the book, Lara Jean runs home right after Peter questions her about the letter. Josh approaches her at her locker the next morning and Lara Jean tells him she is dating someone. She then takes off down the hallway and throws herself at Peter and kisses him there.
To help move the movie along, Lucas also approaches her the same day about his letter.
