The Summer I Turned Pretty and what happens to Belly, Conrad, and Jeremiah

Fans of The Summer I Turned Pretty are eagerly awaiting the end of the series, with the final episodes being released weekly over the summer. The last episode will air on September 17, and everyone has one question on their lips - does Belly end up with Conrad or Jeremiah?
The series is based on a trilogy of books by Jenny Han, and so far the television adaption, on Amazon Prime, has followed the same plot. At the end of season two, we see Belly choosing Jeremiah, which is what happens in the second book, It’s Not Summer Without You.
Warning: spoilers ahead
The third book, We’ll Always Have Summer, follows Belly’s relationship with Jeremiah two years later. This differs slightly in the show - which portrays a four-year time jump. In the third book, Jeremiah admits to cheating on Belly but proposes marriage and the couple plan their wedding while trying to convince their family and friends to support their upcoming nuptuals.

However, Belly and Conrad spend more time together over the summer and he ultimately reveals how he feels about her. The wedding day arrives and Jeremiah opens a letter his mother, Susannah, left for him - but the envelopes were switched and he ends up reading a letter meant for Conrad.
Susannah writes in her letter to Conrad that she only ever saw him in love once, and it was with Belly. When Jeremiah confronts Belly, she tells him she has let Conrad go, but he doesn’t believe her. The wedding is then called off.
At the end of the book, Belly goes to study abroad before eventually reuniting with Conrad several years later at her college graduation. They get married, and Jeremiah even attends the wedding.
Han revealed that although much of the show has followed the books, this may not be the same with the ending. She told Elite Daily that she is “always changing things up”, saying: “People will be like, ‘Why are you changing that? That was working well!’ But to me, it could always be better. That's how I approach everything, so naturally I was going into this story feeling like I wanted to make it even better and try new things.”
Fans have made it clear they want the show’s ending to follow the book, with one writing online: “Now before tsitp s3 comes out I just want to say that they SHOULD stick to the book ending in which she ENDS UP WITH CONRAD.”
Another posted on X: “I swear if belly says ‘I choose me’ at the end of TSITP, I’m MAD. There’s a book everyone knows and loves so follow it. Being team Conrad isn’t a choice, it’s the literal book ending.” A third said: “Hoping this last season of TSITP goes by the book ending!”
