Major Plot Spoilers: What Happens in 'We'll Always Have Summer'?

Season 3 will adapt the events of Jenny Han’s third and final novel, *We'll Always Have Summer*. While the show has taken creative liberties in previous seasons (like the expanded role of Taylor and Steven, and the inclusion of Cam Cameron), the core dramatic structure of the final book is expected to remain the same: Belly must make a final, life-changing choice.

The season will pick up after Belly and Jeremiah have officially decided to be together, entering a relationship that continues into their college years. However, the shadow of Conrad Fisher—Belly’s first love and Jeremiah’s brother—looms large, especially as he is clearly still in love with her.

The Engagement and the Wedding Debacle

The central, explosive plot point of the third book revolves around Belly and Jeremiah’s decision to get married. In the novel, they decide to make things "forever" after a tumultuous period, leading to a planned wedding. This decision is the catalyst that forces Conrad to confront his feelings and finally tell Belly that he loves her, creating the ultimate conflict.

The show is highly likely to feature this engagement and the subsequent drama. The wedding plot serves as the final, irreversible line in the sand, forcing Belly to choose not just who she loves, but who she wants to spend the rest of her life with. This high-stakes drama is what the 11-episode run is designed to fully explore.

Belly's Final Choice: Team Conrad or Team Jeremiah?

The burning question that has fueled the entire series—who does Belly end up with?—is finally answered in the third book. In the novel, Belly ultimately breaks off her engagement with Jeremiah after realizing that while she loves him, her true, soulmate-level connection is with Conrad.

The book's ending sees Belly and Conrad reconcile and eventually get married a few years later, confirming the "Bonrad" endgame. Fan theories for the show suggest that the series may give Belly more "autonomy" in her decision, perhaps having her call off the wedding herself, rather than being forced by external circumstances, to emphasize her growth throughout the trilogy.

Exploring Key Subplots: Steven, Taylor, and the Future

While the love triangle is the main event, Season 3 must also resolve the compelling subplots that have developed beyond the books, particularly the fan-favorite relationship between Belly's brother, Steven Conklin, and her best friend, Taylor Jewel (known as "Staylor").

The Future of Staylor

In the books, Steven and Taylor never officially get together, but the show has heavily invested in their chemistry and relationship arc. Season 2 left their future uncertain, and the final season is expected to provide a definitive answer for the couple. Many fans predict that the events of the final summer, and the wedding drama, will force Steven and Taylor to maturely navigate their feelings and ultimately end up together, providing a secondary romantic conclusion to the series.

Life Beyond Cousins Beach

The final season will also explore the characters’ lives as they transition into young adulthood and college. The source material features a time jump, showing Belly and Conrad's wedding a few years after the initial drama. It is highly anticipated that the show will use its extended episode count to explore this transition, showing the characters grappling with their future careers, their relationships with their parents (Laurel Conklin), and the lasting legacy of Susannah Fisher. The final episodes will likely feature a graduation, a new chapter, and the sense of nostalgia that comes with leaving the innocence of Cousins Beach behind.

With the premiere date set for July 16, 2025, and an 11-episode run to unpack all the drama, *The Summer I Turned Pretty* Season 3 is poised to be the most talked-about series of the summer, finally giving fans the definitive ending they have waited for.
