The final season, adapted from Jenny Han's final novel, We'll Always Have Summer, delivered on its promise of a definitive answer, but not without throwing in a few major, heart-wrenching twists that changed everything fans thought they knew.

The entire journey, from the debutante ball to the final moments at Cousins Beach, was about Isabel "Belly" Conklin finding herself while navigating the complex grief and affection for Conrad and Jeremiah Fisher.

• Isabel “Belly” Conklin (Lola Tung): Belly started the final season in a committed relationship with Jeremiah, which escalated into an engagement. Her focus shifted from being passively chosen to actively choosing her path and her partner. The finale was ultimately about her choosing her own happiness and the love that felt most authentic to her.
• Conrad Fisher (Christopher Briney): Conrad spent much of the second and third seasons grappling with grief over his mother Susannah’s death and his lingering feelings for Belly. He often seemed closed off, prioritizing his studies (pre-med at Stanford) and his emotional distance. His major arc was learning to be vulnerable and confessing his true feelings, even if it meant losing Belly.
• Jeremiah Fisher (Gavin Casalegno): Jeremiah emerged as the "safe" and emotionally present choice in Season 2. His relationship with Belly was intense and culminated in a surprise engagement. His character’s final challenge was accepting that, despite his efforts, a first love—Conrad—held a deeper, more foundational place in Belly’s heart.

The final moments of the season showed Belly and Jeremiah holding hands in the car as he drove her home, solidifying their new relationship status. The episode also ended with Belly rejoining her high school volleyball team, symbolizing her re-centering on her own life and ambitions outside of the Fisher family drama.

Major Book Differences Introduced

Season 2 also introduced significant deviations from the source material, setting the stage for an unpredictable final season. The introduction of Aunt Julia and her child Skye, who initially planned to sell the beach house, added new family dynamics not present in the books. Furthermore, the show’s decision to have Belly and Jeremiah become engaged early in Season 3, a plot point directly adapted from the third novel, raised the stakes considerably, making the eventual breakup even more impactful.

The Series Finale Explained: The 5 Biggest Twists That Confirmed the Endgame

The final episode of The Summer I Turned Pretty, which concluded the adaptation of We'll Always Have Summer, delivered the long-awaited resolution to the love triangle. Here are the five most significant moments that sealed Belly's final choice and confirmed the series' ultimate endgame couple.

1. The Broken Engagement

The central conflict of Season 3 revolved around Belly and Jeremiah’s engagement. Despite the commitment, their relationship began to crumble under the weight of their youth and unresolved feelings for Conrad. The engagement was ultimately called off, a necessary step that freed both Belly and Jeremiah to pursue their individual paths and, crucially, allowed Belly to re-evaluate her feelings for Conrad.

2. Conrad’s Honest Confession

The turning point arrived when Conrad finally confessed his enduring love for Belly. This wasn't a fleeting summer declaration but a mature, vulnerable admission of his feelings. According to the finale recap, Conrad’s open heart was the catalyst that led to the end of Belly and Jeremiah's engagement, proving that his feelings were too strong to ignore.

3. Jeremiah's Acceptance of "Endgame"

In one of the most mature moments of the series, Jeremiah accepted the reality of the situation. He recognized that Belly’s love for Conrad was a deep, childhood-rooted connection that he could not fully replace. This acceptance was a huge win for "Team Belly," as it showed Jeremiah prioritizing her happiness over his own desire to keep her close, signifying his own emotional growth.

4. The Paris Independence Arc

A significant plot point leading up to the finale involved Belly's time in Paris, where she gained a new sense of independence. This time away from both brothers allowed her to finally choose herself first. Her final decision was not just about choosing a brother, but about choosing the future and the person that best aligned with her independent self.

5. The Flash-Forward to Cousins Beach

The series concluded with a satisfying flash-forward. The final scenes show Belly and Conrad happily together at the Cousins Beach house, the place where their entire story began. While there was no explicit sign of a wedding ring, the visual confirmation of them together, relaxed and happy in their element, cemented Conrad as the definitive "endgame" partner for Belly. The final shot of them at the beach house served as a poetic and complete closure for the love triangle.

What About Steven and Taylor? The Other Relationship Resolution

While the focus was on the Belly-Fisher brothers dynamic, the finale also provided a significant update on the fan-favorite couple, Steven Conklin and Taylor Jewel. Their relationship faced a major test when Steven's startup, co-founded with Denise, secured seed funding. This venture required Steven to move to San Francisco, creating a long-distance challenge for the couple. The finale left their future open but with a foundation of commitment, mirroring the realistic complexities of young adult relationships.

Ultimately, The Summer I Turned Pretty series finale was a powerful conclusion that honored the source material while also providing a fresh, mature take on the love triangle. It was a finale for "Team Belly," proving that the right choice is the one that allows you to be your truest self.
