The Major Way The Summer I Turned Pretty TV Show Changed Jeremiah & Belly's Cheating Storyline From the Books
. We're finally back at Cousins for the last season of the hit Amazon series, and there's one major twist that was faithfully adapted from the book.
The third season of the series is based on the third book, called We'll Always Have Summer. Series creator and writer Jenny Han did say that the series didn't have to completely follow the premise of the books she wrote. That isn't to say that every piece of the TV series will follow the book. 'If you knew exactly what was going to happen, it wouldn't be a very satisfying show-watching experience,' Han told Time in 2023. 'Part of the enjoyment of watching TV or movies is that you don't know. I am always trying to preserve the audience experience—my aim is to surprise and delight and to give the fans the best possible story.'

Who Does Belly End Up With in The Summer I Turned Pretty? Season 3 Isn't 'Exactly the Same'
TSITP's Christopher Briney & His GF Have an Eerily Similar Love Story to Conrad & BellyThe series and book have a two-year jump between the events of the previous book/season. One of the crucial plot points of both mediums is when Jeremiah cheats on Belly. In fact, it's revealed within the first half of the first episode.
When does Jeremiah cheat on Belly?
Like the show, Jeremiah cheated on Belly before the events of the book. In chapter three of We'll Always Have Summer, Belly overhears Lacie at a frat party talking to a friend that she hooked up with Jeremiah.
Belly confronts Jeremiah at the party, and he brushes her away until she asks him if he really cheated on her. Jeremiah confesses that he did have sex with Lacie, but thought that he and Belly were broken up at the time. Belly argues that they weren't really broken up, but Jeremiah insists that he didn't know that. She slaps him, and they break up. But in a couple of days, they have a heart-to-heart and realize they don't want to be apart. Jeremiah later proposes, and Belly enthusiastically says yes.
Unlike the books, the Amazon series shows Jeremiah cheating on Belly, not once. But twice, with the same person.
Jenny Han says that it's up to the viewer if Jeremiah actually cheated or not. 'It's debatable whether or not that's considered cheating or not,' she told People. 'Because they technically were broken up. It's really how different people [interpret it].'
Later on in the book, Conrad finds out that Jeremiah cheated on Belly during their 'break,' and tells Belly. Belly tells her former lover that she already knew, which then spirals to Conrad professing his love once Conrad asks Belly to cancel her wedding to Jeremiah and be with him, but she tells him no.
However, things take a turn when Jeremiah reads a letter meant for Conrad from their mother, Susannah, saying that she could only see him with Belly. Jeremiah then confronts Belly about whether she still loved Conrad, and though she protests, he doesn't believe her and calls off the wedding. Belly and Conrad reunite, and they eventually get married.
