The highly anticipated final season of *The Summer I Turned Pretty* is poised to deliver the definitive answer to the most agonizing love triangle in young adult fiction. As of December 13, 2025, anticipation is at an all-time high for Season 3, which is confirmed to be the series' conclusion. The entire season is dedicated to adapting the third and final novel in Jenny Han’s trilogy, *We’ll Always Have Summer*, meaning the fate of Isabel "Belly" Conklin and the Fisher brothers—Conrad and Jeremiah—is about to be sealed. While the show has taken creative liberties, the core narrative arc of the books strongly dictates who Belly ultimately chooses, bringing an emotional and conclusive end to her journey of first love and heartbreak.
The central drama of the series has always revolved around Belly’s heart, torn between the steady, passionate intensity of Conrad and the fun-loving, comforting warmth of Jeremiah. Season 3 will force Belly to confront her deepest feelings and make a choice that will irrevocably change her relationship with both brothers. Fans of the books already know the answer, but show creator Jenny Han has hinted that the television adaptation will offer a "hopeful" ending, focusing on Belly "honoring herself" as she navigates the transition from a young girl's summer crush to a woman's lifelong commitment.
The Definitive Book Ending: Belly’s Ultimate Choice
To understand the likely outcome of *The Summer I Turned Pretty* Season 3, one must look to the source material: Jenny Han’s third novel, *We’ll Always Have Summer*. The book provides a clear, decisive answer to the "who does Belly choose?" question, which the show is expected to honor, even with minor plot deviations. The final season will cover the events that lead to the resolution of the love triangle and Belly's eventual marriage.
The Tumultuous Path to the Altar
The third book opens with Belly and Jeremiah in a serious relationship, which eventually leads to an engagement. This decision is often seen by fans as a way for Belly to hold onto the Fisher family and the beloved Cousins Beach life after the tragic loss of Susannah. However, the engagement is fraught with tension and issues, primarily stemming from Belly’s lingering feelings for Conrad and the brothers' fractured relationship.
- The Engagement: Belly and Jeremiah, despite being young, decide to get married, a choice that shocks their families and adds immense pressure to their relationship.
- The Cheating Scandal: A pivotal and deeply painful moment in the book involves a dramatic event that exposes the fundamental cracks in Belly and Jeremiah's foundation, leading to a massive confrontation. This event is a critical turning point that forces Belly to re-evaluate her choices and her true feelings.
- The Breakup: Following the emotional fallout, Belly and Jeremiah call off the wedding. This is a moment of profound personal growth for Belly, as she realizes that marrying Jeremiah was perhaps an attempt to force a future that wasn't authentically hers.
The Team Conrad Victory: A Fated Reunion
After the breakup with Jeremiah, the book details a period of time where Belly steps back from both brothers to focus on herself and her future. This is the period Jenny Han refers to as Belly "honoring herself." She lives her life, attends college, and gains independence—in the book, this is in Spain, but the show has hinted at Paris.
The final, conclusive segment of the book sees Belly and Conrad reconnecting. Their reunion is not a rushed, spontaneous moment but a slow, mature realization that their connection is the one that has endured every trial, every heartbreak, and every summer apart.
The Final Answer: Belly ends up with Conrad. The book concludes with Belly and Conrad getting married at Cousins Beach, the place where their story began.
The Show vs. The Book: Will Season 3 Change the Ending?
While show creator Jenny Han has a history of making changes to her source material for the screen, the core fan intention and narrative structure of *The Summer I Turned Pretty* strongly suggest the final pairing will remain true to the books. The show’s entire emotional framework has been building toward a Belly and Conrad endgame, a dynamic often referred to by fans as "endgame" or "destiny."
Why Team Conrad Is the Inevitable Conclusion
The television series has subtly but consistently reinforced the deep, foundational connection between Belly and Conrad. Their relationship is characterized by a shared history, mutual understanding of grief, and a passionate, if often complicated, bond. Even when they are apart, their feelings for one another drive the plot.
- The Pacing of Heartbreak: Season 2 ended with Belly choosing Jeremiah, giving "Team Jeremiah" their moment in the sun. This follows a classic love triangle structure where the initial pairing (Belly and Conrad) breaks, the protagonist explores the second option (Belly and Jeremiah), only to return to the first, more fated love.
- Jenny Han’s Vision: Han has repeatedly stated that she views the series as a journey of growth for Belly. Choosing Conrad in the end represents a mature choice—a love that is earned through struggle and self-discovery, rather than a comfortable, easy option.
- Thematic Consistency: The central theme of the trilogy is the enduring nature of first, true love. Conrad is consistently portrayed as Belly's first love, her "always" love, a narrative thread that would be broken if she chose Jeremiah in the final act.
Key Entities and the Final Season’s Focus
The final season will not just focus on the love triangle, but on the growth of all the main characters as they transition into young adulthood. The main entities driving the plot will be:
- Isabel "Belly" Conklin (Lola Tung): Her journey of self-discovery, independence, and making a choice that serves her own happiness.
- Conrad Fisher (Christopher Briney): His ability to communicate his feelings, mature beyond his emotional walls, and fight for the love he wants.
- Jeremiah Fisher (Gavin Casalegno): His struggle with his brother and his own worth, and ultimately, his acceptance of Belly's choice.
- Steven Conklin (Sean Kaufman) & Taylor (Rain Spencer): Their developing relationship will serve as a parallel storyline to Belly’s, offering moments of levity and stability.
- Laurel Park (Jackie Chung) & Cleveland Castillo (Alfredo Narciso): Laurel’s continued journey with grief and her own romantic life will provide the adult backdrop.
- Cousins Beach: The iconic setting will, once again, be the backdrop for the most pivotal moments, including the final reunion.
The Emotional Stakes: What Belly Choosing Conrad Means for Jeremiah
The resolution of the love triangle is a bittersweet moment. While "Team Conrad" fans will celebrate, the ending is inherently painful for Jeremiah and the "Team Jeremiah" camp. The final season must handle the breakup with grace and respect for Jeremiah’s character, who is a beloved part of the series.
In the book, Jeremiah's reaction is one of deep hurt and resignation. The ending is not a total loss for him; it's a moment of clarity where he realizes he deserves a love that is fully committed to him. The show is expected to give Jeremiah a respectful send-off, allowing him to move on and find his own path to happiness, separate from his brother and Belly.
Ultimately, *The Summer I Turned Pretty* Season 3 is about more than just who Belly chooses; it's about Belly choosing herself first, and then choosing the partner who aligns with her truest self. Based on the book's definitive ending and the consistent thematic groundwork laid by Jenny Han throughout the series, Belly ends up with Conrad Fisher in the final season. This conclusion solidifies their fated, enduring romance as the heart of the entire trilogy.
