The Plot: What to Expect from the Final Chapter

Season 3 is based on the third novel, *We’ll Always Have Summer*, and will feature a significant time jump. This narrative leap means that Belly Conklin (Lola Tung) and the Fisher brothers—Conrad (Christopher Briney) and Jeremiah (Gavin Casalegno)—will be navigating their lives a couple of years after the events of Season 2.

The core of the final season revolves around *Belly's choice* and the ultimate resolution of the central *love triangle*. At the end of Season 2, Belly chose Jeremiah, but the lingering tension and Conrad’s deep, unspoken feelings are far from over. The final installment will explore:

• Belly and Jeremiah’s College Relationship: The season will pick up with Belly and Jeremiah as a couple in college, seemingly happy, but facing the pressures of their young relationship.
• Conrad Fisher’s Future: Conrad is attempting to move on and keep his distance, but his love for Belly remains a powerful, constraining force, especially as she is his brother’s fiancée.
• The Steven and Taylor Arc: Steven Conklin (Sean Kaufman) and Taylor (Rain Spencer) will also face major relationship challenges, including a potential car accident and a conflict over Steven's startup requiring a move to San Francisco, testing their commitment.
• The Ultimate Decision: The series, like the book, must ultimately bring Belly to a final, permanent choice, deciding once and for all who she is meant to be with.

The decision to end the show with Season 3 was intentional, as show creator and author Jenny Han wanted to honor the structure and emotional integrity of the original *book trilogy*. This ensures that the series avoids unnecessary filler and delivers the true ending that fans of the books have anticipated.

The Main Cast and Key Characters (Topical Authority)

The emotional weight of *The Summer I Turned Pretty* rests entirely on the shoulders of its main cast. The following actors are confirmed to return for the final season to complete the story of the *Conklin* and *Fisher* families.

The Core Cast of Cousins Beach

• Lola Tung as Isabel “Belly” Conklin: The protagonist whose coming-of-age story and complicated love life form the heart of the series.
• Christopher Briney as Conrad Fisher: The brooding, emotionally guarded older brother who is Belly’s first love.
• Gavin Casalegno as Jeremiah Fisher: The sweet, golden younger brother who is Belly’s best friend and current boyfriend.
• Sean Kaufman as Steven Conklin: Belly's older brother, whose own relationship with Taylor is a major secondary plot.
• Rain Spencer as Taylor: Belly’s best friend, who is navigating her own complex relationship with Steven.
• Jackie Chung as Laurel Park: Belly and Steven’s mother, a writer whose personal life and grief over Susannah are central themes.
• Rachel Blanchard as Susannah Fisher: Conrad and Jeremiah’s mother, whose death is the emotional catalyst for much of the drama in Season 2.

The return of these key players, including the *Fisher brothers*, ensures that the final season will provide the necessary closure to every major character arc. The show’s ability to weave together the stories of the teenagers and their parents, such as *Laurel Park*, has been a major factor in its success, building a rich world beyond just the *Belly and Conrad* vs. *Belly and Jeremiah* dynamic.

TSITP vs. The Book Trilogy: The Final Differences

While the show generally follows the plot of the books, it has introduced several key differences that make the Season 3 plot less predictable, even for book readers. The biggest changes include:

• Steven's Increased Role: Steven Conklin has a much larger, more developed storyline in the show, particularly with his relationship with Taylor, which is expected to be a major focus of the 11-episode final season.
• The Debutante Ball: The show added the element of the debutante ball in Season 1, which was not a part of the original book.
• The Car Accident: The show introduces a car accident involving Steven, which is a new dramatic element that will likely have repercussions in the final season.

These changes mean that while the ultimate ending of *Belly's choice* is likely to follow the *Jenny Han book trilogy*, the journey to get there will be fresh and unique to the Prime Video series. The extended episode count for the final season suggests that the showrunners plan to spend more time on these original storylines while still delivering the iconic moments from *We’ll Always Have Summer*.

In conclusion, fans can rest assured that the saga of *The Summer I Turned Pretty* is not canceled, but rather concluding as intended with three complete seasons. The final 11-episode chapter, premiering in July 2025, will bring the long-awaited resolution to the love triangle and the emotional story of the two families at *Cousins Beach*.
