Major Plot Spoilers: The Two-Year Jump and Belly's College Life
Season 3 of The Summer I Turned Pretty faithfully adapted the core conflict of the final novel, "We'll Always Have Summer," by introducing a significant time jump. The season picked up two years after the events of Season 2, finding Belly and Jeremiah firmly established in their relationship, both attending Finch College. This time jump immediately sets a more mature, high-stakes tone for the series.
The initial episodes focused on the stability of Belly and Jeremiah's life at Finch, contrasting sharply with the lingering, unresolved feelings between Belly and Conrad. Conrad, who was now a student at Stanford, was still a looming presence in Belly’s life, primarily through his brother and their shared history at Cousins Beach.
The Cheating Scandal and the Fateful Proposal
The biggest catalyst for the season's drama was the revelation of Jeremiah's infidelity. While Belly was away, Jeremiah cheated on her with a girl named Lacie at a party. This pivotal moment, a direct adaptation from the book, shatters the seemingly perfect relationship between Belly and Jeremiah.
In a desperate, ill-conceived attempt to prove his commitment and save their relationship, Jeremiah proposes to Belly. The proposal itself, which takes place during their college years and is driven by crisis rather than true readiness, becomes the central conflict. Belly, in a state of confusion and a desire to hold onto the past, accepts. This decision forces the entire group—Belly, Jeremiah, Conrad, Steven, and Laurel—to return to the one place that holds all their memories: Cousins Beach, to plan a wedding that everyone, especially Conrad, knows is a mistake.
The Final Showdown: Conrad, Jeremiah, and Belly's Ultimate Choice
The drama of the impending wedding at Cousins Beach is where the love triangle reaches its climax. The season masterfully used the 11 episodes to build tension, with Conrad struggling to accept the marriage, Jeremiah fighting for his future with Belly, and Belly herself grappling with the reality of her choice. The entity of the beach house, a symbol of their shared childhood and Susannah's memory, becomes the backdrop for their final reckoning.
The Unraveling of the Engagement
As the wedding planning progresses, the cracks in Belly and Jeremiah's relationship become impossible to ignore. Conrad's quiet despair and enduring love for Belly are constant reminders of the path she didn't take. A major turning point in the series is a confrontation between the three leads where the truth about Jeremiah's cheating is fully exposed in front of Conrad, leading to an explosive argument and a physical fight between the brothers.
The realization that her engagement was rooted in a reaction to pain, not a stable, long-term love, finally hits Belly. She calls off the wedding, recognizing that she and Jeremiah are not ready for marriage and that her heart has always belonged to someone else. This is a moment of profound growth for Belly, moving from a girl defined by her crush to a woman making a difficult, mature decision.
Belly and Conrad's Final Ending
The final episodes of Season 3 focus on the aftermath of the broken engagement and the slow, deliberate reconciliation between Belly and Conrad. After a period of necessary space, Belly returns to Cousins Beach and finds Conrad there. Their reunion is less dramatic than their previous encounters and more grounded in mutual respect and a deeper understanding of their connection. The series highlights that their relationship is built on a foundation of shared history, intellectual connection, and an undeniable, enduring love.
In the series finale, which aired on September 17, 2025, Belly and Conrad finally get their happily ever after. The final scene jumps forward again, showing Belly graduating from college (Finch University) and receiving a letter. The very last moments of the series depict Belly and Conrad getting married on the beach at Cousins, a small, intimate ceremony that perfectly encapsulates their journey. This ending is a powerful nod to the book’s conclusion, satisfying the 'Team Conrad' fans while providing a sense of closure for all the characters.
The Legacy of The Summer I Turned Pretty
The conclusion of The Summer I Turned Pretty not only settled the 'Team Conrad vs. Team Jeremiah' debate but also solidified the series' place in the pantheon of popular Young Adult romance dramas. The show's success is a testament to the enduring appeal of Jenny Han's storytelling, which perfectly captures the bittersweet essence of growing up, first love, and the magic of Cousins Beach. The series explored complex entities such as grief, family loyalty, and the transition from adolescence to adulthood with sensitivity.
The show's legacy extends beyond the central romance, highlighting the strong friendship between Belly and Taylor, the deepening bond between Steven and Taylor, and Laurel's journey through grief and finding her own voice as a writer. The final season provided a satisfying, if emotional, end to the story of Belly Conklin and the Fisher brothers, leaving fans with the lasting image of a perfect summer at the beach.
