The Summer I Turned Pretty Season 1: 7 Explosive Secrets And Moments That Defined Belly’s First Summer At Cousins Beach

Contents
As of December 23, 2025, *The Summer I Turned Pretty* Season 1 remains the quintessential summer viewing experience, a vibrant, sun-drenched adaptation of Jenny Han's beloved novel that launched a global phenomenon. This initial seven-episode run didn't just introduce us to Isabel "Belly" Conklin’s transformative sixteenth summer at Cousins Beach; it expertly set the stage for one of television’s most debated love triangles, blending coming-of-age nostalgia with raw, emotional drama. The debut season is a masterclass in capturing the feeling of first love, first heartbreak, and the painful realities of growing up, all against the backdrop of the idyllic, yet complicated, Fisher beach house. It's a foundational story that every fan returns to, examining the pivotal moments that shaped Belly's relationship with the Fisher brothers, Conrad and Jeremiah, and the devastating secret that hung over the two families.

The Core Cast and Characters That Launched the Phenomenon

The success of *The Summer I Turned Pretty* hinges entirely on its talented ensemble cast, who brought the deeply cherished characters from Jenny Han's book to life. The first season focused heavily on the core group, establishing their complex relationships and individual struggles.

  • Isabel “Belly” Conklin (Lola Tung): The protagonist, who turns 16 and experiences a physical and emotional transformation during her summer at Cousins Beach. She navigates her first serious relationships and the complicated feelings she has for both Fisher brothers.
  • Conrad Fisher (Christopher Briney): The older, brooding, and emotionally distant Fisher brother, who has been Belly's long-time crush. His moody behavior throughout the summer is a central mystery.
  • Jeremiah “Jere” Fisher (Gavin Casalegno): The younger, fun-loving, and openly affectionate Fisher brother, who develops a serious romantic interest in Belly. He is the immediate, easier choice in the love triangle.
  • Susannah Fisher (Rachel Blanchard): Conrad and Jeremiah's mother, Laurel's best friend, and Belly's beloved "Aunt Susannah." Her secret illness is the driving force behind the season's hidden drama.
  • Laurel Park (Jackie Chung): Belly's mother and Susannah's best friend. A newly divorced novelist struggling with writer's block and the changing dynamic of her relationship with her daughter.
  • Steven Conklin (Sean Kaufman): Belly's older brother, who spends the summer working and grappling with his own romantic entanglements and the impending reality of college.
  • Cam Cameron (David Iacono): Belly's first official boyfriend of the summer, a sweet, low-drama figure who offers a brief respite from the Fisher brother drama.
  • Cleveland Castillo (Alfredo Narciso): A fellow author who Laurel meets and connects with over their shared experiences with writing and loss.

7 Explosive Secrets and Defining Moments of Season 1

Season 1, spanning seven episodes, was packed with significant milestones, emotional reveals, and relationship developments that solidified the series' place in the teen drama landscape. These moments were crucial in defining the trajectory of Belly's summer and the future of the Conklin and Fisher families.

1. Belly’s Debutante Ball Transformation

The season centers around Belly's unexpected participation in the annual Cousins Beach Debutante Ball, a tradition Susannah cherishes. This moment is the visual representation of the show's title—Belly's "turning pretty." It's where she fully steps into her new identity, attracting attention not only from Conrad and Jeremiah but also from new love interest Cam. The Deb Ball itself, filmed at the beautiful Cape Fear Country Club, serves as the dramatic backdrop for the finale, forcing all the season's tensions to a head.

2. The Devastating Secret of Susannah’s Cancer

The biggest, most heartbreaking secret of Season 1 is the revelation that Susannah Fisher's cancer has returned. This knowledge is the key to understanding Conrad's moody, distant behavior throughout the summer. He knew about his mother's illness and kept it secret, causing him to push Belly and everyone else away. The finale sees the truth finally come out, shattering the illusion of a perfect summer and bringing the two families together in shared grief.

3. The Cam Cameron Interlude

In an effort to move past her complicated feelings for Conrad, Belly briefly dates Cam Cameron, a gentle and kind boy she meets on the beach. This relationship, while short-lived, is a vital part of Belly’s journey, offering her a taste of a simple, uncomplicated romance before the full weight of the Fisher drama pulls her back in. It also establishes the idea that Belly is actively exploring her feelings and not just passively waiting for Conrad.

4. Jeremiah’s Confession and First Kiss

While Conrad struggles to articulate his feelings, Jeremiah is open and present. His confession that he loves Belly and their subsequent first kiss is a massive turning point. It's an emotionally charged moment that officially ignites the love triangle, forcing Belly to confront the fact that her feelings for the brothers are more complex than a simple childhood crush. This relationship offers her the immediate, passionate connection she craves.

5. The Beach Bonfire Confrontation

A significant emotional climax occurs during the beach bonfire, a classic Cousins Beach tradition filmed at locations like Carolina Beach and Wrightsville Beach. This is where the tension between Conrad and Jeremiah over Belly boils over. Conrad’s jealousy and inability to communicate clash with Jeremiah’s frustration, leading to a heated argument that leaves Belly feeling like a prize between them.

6. The Debutante Ball Dance and Conrad’s Declaration

The season finale's biggest romantic payoff comes during the Deb Ball. After a stressful day where Jeremiah is initially absent due to the cancer revelation, Conrad steps in as Belly's escort. As they dance, Conrad finally opens up, telling Belly, "I do still want you," and they share a pivotal kiss. This declaration, though late, solidifies his position as her true love interest by the season’s end and sets the stage for their relationship in the following season.

7. The Heartfelt Beach Promise

The final scene of Season 1 is one of its most iconic. Following the Deb Ball, Belly and Conrad share a quiet moment on the beach, where they kiss and walk hand-in-hand. This scene, set to a perfect Taylor Swift soundtrack, confirms Belly's choice (for now) and ends the summer on a note of hopeful, albeit complicated, new love. The emotional weight of Susannah's illness is present, but the focus is on the fleeting joy of a first love finally realized.

The Lasting Impact of the Cousins Beach Setting

The setting of Cousins Beach is practically a character in itself, and the production team went to great lengths to bring its idyllic, wealthy, coastal vibe to life. Filming primarily took place in the Wilmington area of North Carolina, utilizing the beautiful beaches and coastal towns to create the fictional setting.

The iconic Fisher beach house, with its cozy, coastal grandmother interiors, was meticulously designed to evoke a feeling of timeless summer nostalgia. The choice of Wilmington and its surrounding areas, including Southport for local scenes, lent an authentic, sun-drenched atmosphere that made the show an instant summer staple. This attention to detail in the setting is a key reason why the first season felt so transportive and immediately captured the essence of Jenny Han's novel.
