Belly and Jeremiah’s Failed Engagement

The relationship between Belly and Jeremiah reaches its peak—and its breaking point—in the third book, We'll Always Have Summer. Their relationship takes a very serious turn when they are both in college, but their happiness is shattered by a devastating betrayal. Belly discovers that Jeremiah has cheated on her while they were briefly on a break.

In a desperate attempt to prove his commitment and salvage their relationship, Jeremiah proposes marriage to Belly. Despite her initial hesitation and the emotional turmoil caused by his infidelity, Belly accepts the proposal on the condition that he never hurts her again. This impulsive decision, made in the shadow of a serious relationship crisis, is met with shock and disapproval from their families, especially Belly's mother, Laurel, and the boys' aunt, Susannah's sister. The family's disapproval stems from the young couple's age and the circumstances surrounding the proposal.

The planning for the wedding becomes a major focus of the final book, with Belly even trying on a wedding dress. However, the emotional strain and the lingering presence of Conrad Fisher in their lives prove too much. The weekend of the planned wedding is where the final, heartbreaking confrontation occurs. Conrad, who is still deeply in love with Belly and believes she is making a mistake, finally tells her how he feels. This confrontation forces Belly to confront her true feelings and the reality of her relationship with Jeremiah.

Ultimately, Belly realizes that she cannot marry Jeremiah, not just because of the cheating incident, but because she is still truly in love with his older brother. She calls off the wedding, bringing the "Jelly" relationship to a definitive end.

The Final Chapter: Belly and Conrad’s Destiny

The conclusion of the novel details a time jump that confirms the true endgame of the series. After the dramatic breakup with Jeremiah and the canceled wedding, Belly takes time for herself to grow up and mature, moving in with friends at college. The distance and time allow her to process her feelings and for her relationship with Conrad to slowly and organically rekindle.

Years later, a flash-forward reveals the ultimate, romantic resolution: Belly and Conrad get married. Their wedding is a small, intimate ceremony at Cousins Beach, the place where their entire story began. The details are a perfect, full-circle moment for the couple known as "Bonrad."

In a final, poignant detail, Jeremiah is present at the wedding, having moved on from the painful past. He attends the ceremony with a date, showing that while the romantic relationship with Belly ended, the deep, familial bond between all three of them—a bond forged by years of shared summers and their mothers' close friendship—ultimately survived the love triangle.

Will the TV Show Change the Ending? Season 3 Clues and Author's Intent

Since its debut, the television adaptation of The Summer I Turned Pretty has not been afraid to deviate from the source material, leading many fans to speculate about a potential change in the endgame. Showrunner and author Jenny Han has made comments that fuel this uncertainty, suggesting the show’s conclusion might not be as "neat" as the books.

• Author's Tease: Jenny Han has previously suggested that Belly doesn't *have* to choose one of the brothers, a comment that could imply a different path for the TV series. However, the definitive nature of the book's ending makes a major change unlikely, as it would fundamentally alter the core story that fans love.
• The Season 3 Adaptation: The third season is confirmed to be based on We'll Always Have Summer, meaning the central dramatic events—Jeremiah’s cheating, the impulsive proposal, the cancelled wedding, and the ultimate reunion of Belly and Conrad—are all expected to be adapted.
• Leaked Hints: Recent production leaks and call sheets for Season 3 have hinted at key scenes from the final book, including a significant reunion moment between Belly and Conrad in Paris and the appearance of the famous love letters. These clues strongly suggest that the show is following the book's path toward the "Bonrad" endgame.

While the series has expanded Jeremiah's role and deepened his relationship with Belly (the "Jelly" romance), the fundamental narrative structure of the story is built around Belly's realization that her soulmate is the boy who has always truly seen her, the one she loved first: Conrad Fisher. The dramatic tension of the love triangle serves to show why the relationship with Jeremiah, while passionate and fun, is ultimately not the one that lasts forever.
