'To All The Boys I've Loved Before' Is Based On A Book — But The Ending Is Very Different

If you're a sucker for a movie (or book) about love letters, "fake" relationships, and the power of sisterhood, you're definitely going to want to a) come and be my best friend and b) watch Netflix's new rom-com To All The Boys I've Loved Before, based on the young adult novel of the same name by Jenny Han. The movie will be available to stream on Friday, August 17.

To All The Boys I've Loved Before is the story of Lara Jean Song Covey, who lives with her older sister, Margot, her younger sister, Kitty, and her dad, a doctor. She's never had a boyfriend, but she's definitely had crushes — five of them, to be exact. She never told them how she felt, but she did write each of them a love letter, all of which she now keeps in a teal box her mother gifted to her before she died.

In both the book and movie, here's what goes down: Before Margot leaves for college in Scotland, she decides to breakup with her boyfriend, Josh Sanderson. Lara Jean had a crush on Josh before he started dating her sister, and with Margot out of the country, she finds her feelings for him coming back. But she has a way bigger problem to worry about: Her letters were mysteriously mailed out to her crushes, and some of the boys want answers — including Josh. In a desperate attempt to avoid dealing with him, Lara Jean agrees to a "fake relationship" with Peter Kavinsky, one of her letter recipients, who wants to "date" her in order to make his ex-girlfriend jealous. But things get complicated when they start to develop real feelings for each other. After a ski-trip mishap, the two "breakup" without having disclosed how much they actually like each other.

OK, here's where things diverge a little. The book ends with Lara Jean and Peter still broken up. But it gives readers a glimmer of hope, because it ends with the lines: "Dear Peter." Lara Jean is going to write him a love letter, but it never indicates that she gives it to him or gets back together with him.

The movie ending is less... ambiguous.

But don't worry, Netflix isn't re-writing the books. Let me explain: To All The Boys I've Loved Before is actually the first in a trilogy of books about Lara Jean Covey. A reconciliation between Lara Jean and Peter doesn't take place in book one, but it does take place in book two, P.S. I Still Love You. But if you think the drama ends when they get back together, you are extremely wrong. Because in book two, author Jenny Han also introduces readers to John Ambrose McClaren, Lara Jean's crush from Model U.N. who also received one of her love letters in the mail. I won't give too much away, but let's just say that John Ambrose is a worthy competitor for her affection.

There's no word yet on whether or not To All The Boys I've Loved Before is getting a Netflix sequel, but there's certainly way more to Lara Jean Covey's story in the trilogy.
