Cast of The Summer I Turned Pretty: Full Seasons 1-3 List

If you’ve been watching Belly fall for the Fisher brothers across three summers, you’ve probably wondered who’s actually behind those characters. The Summer I Turned Pretty has built a loyal following since its June 2022 premiere on Prime Video, and the cast has grown from a tight core ensemble to a full ensemble of new faces. Whether you’re catching up before the rumored film continuation or just want to match names to faces, here’s the complete breakdown.

Lead Actress (Belly): Lola Tung · Conrad Fisher: Christopher Briney · Jeremiah Fisher: Gavin Casalegno · Steven Conklin: Sean Kaufman · Laurel Park: Jackie Chung

These key facts establish the show’s footprint across its three-season run on Prime Video.

Cast of The Summer I Turned Pretty Season 1

Seven performers formed the emotional center of the first season, which dropped on Prime Video in June 2022. The love triangle between Belly and the two Fisher brothers drove most of the drama, supported by a tight family cast.

Core Ensemble

• Lola Tung as Isabel “Belly” Conklin — the protagonist whose summers at Cousins Beach shape her coming-of-age journey (Wikipedia)
• Christopher Briney as Conrad Fisher — Susannah’s eldest son, described as brooding and emotionally guarded (Wikipedia)
• Gavin Casalegno as Jeremiah Fisher — the younger brother, portrayed as warmer and more openly affectionate (Wikipedia)
• Sean Kaufman as Steven Conklin — Belly’s older brother, who develops a romance with Shayla (Wikipedia)
• Jackie Chung as Laurel Park — Belly and Steven’s mother and a published author (Wikipedia)

Recurring Roles

• Rachel Blanchard as Susannah Fisher — the matriarch whose health struggles become a central storyline (Wikipedia)
• Colin Ferguson as John Conklin — Laurel’s ex-husband and historian (Wikipedia)
• Tom Everett Scott as Adam Fisher — the brothers’ father and venture capitalist (Wikipedia)
• Alfredo Narciso as Cleveland Castillo — a visiting author who shares an intellectual connection with Laurel (Wikipedia)
• David Iacono as Cam — a local love interest for Belly in seasons 1–2 (Wikipedia)
• Minnie Mills as Shayla — Belly’s debutante peer and Steven’s romantic interest (Wikipedia)

The pattern here is clear: creator Jenny Han built season 1 around three overlapping family units—the Conklins, the Fishers, and the seasonal visitors at Cousins Beach—giving each actor a distinct relational role within the ensemble.

Cast of The Summer I Turned Pretty Season 2

Season 2 premiered on July 14, 2023, expanding the world with eight episodes and bringing in characters who deepen the emotional stakes for the core trio.

Returning Cast

• Lola Tung returns as Belly, now navigating a more serious relationship dynamic (Wikipedia)
• Christopher Briney as Conrad, whose emotional walls begin to crack under mounting pressure (Wikipedia)
• Gavin Casalegno as Jeremiah, increasingly asserting his own identity separate from his brother (Wikipedia)
• Sean Kaufman as Steven, now more established in his college life (Wikipedia)
• Jackie Chung as Laurel, continuing her author storyline alongside Cleveland (Wikipedia)
• Rachel Blanchard as Susannah, facing the full weight of her health crisis (Wikipedia)

New Additions

• Elsie Fisher as Skye — Julia’s daughter and the cousins’ newly introduced cousin, who brings a fresh perspective to the Fisher family dynamics (Wikipedia)
• Kyra Sedgwick as Julia — Susannah’s estranged older half-sister and Skye’s mother, whose arrival disrupts the established summer rhythm (Wikipedia)
• Rain Spencer elevated to main cast as Taylor Jewel, Belly’s best friend whose relationship with Steven becomes an on-again/off-again storyline (Wikipedia)
• Summer Madison as Nicole — Belly’s friend and Conrad’s brief love interest in seasons 1–2 (Wikipedia)

The catch with season 2’s additions is that Skye and Julia function as emotional mirrors for the main characters—Skye mirrors the uncertainty of youth, while Julia mirrors the unresolved family tensions that Susannah never addressed.

Cast of The Summer I Turned Pretty Season 3

The third and final season arrived on July 16, 2025, with 11 episodes and a four-year time jump that reframes every character’s trajectory.

Confirmed Returning Actors

• Lola Tung as Belly — now finishing her third year of college and dating Jeremiah (Cosmopolitan)
• Christopher Briney as Conrad — navigating life post-college with new professional pressures (About Amazon)
• Gavin Casalegno as Jeremiah — now partnered with Belly and building a more confident identity (Cosmopolitan)
• Sean Kaufman as Steven — graduated early from Princeton and interning for Adam Fisher’s venture capital firm (Cosmopolitan)
• Jackie Chung as Laurel — continuing her literary career with new creative challenges (Wikipedia)
• Rain Spencer as Taylor Jewel — now main cast with a sorority storyline involving new character Lacie (Wikipedia)

Announced New Cast

• Sofia Bryant as Anika — Belly’s college roommate who provides a window into campus life (Wikipedia)
• Isabella Briggs as Denise — Steven’s office co-worker in the venture capital firm (Wikipedia)
• Kristen Connolly as Lucinda Jewel — Taylor’s mother, who appears in the expanded family storyline (Wikipedia)
• Lily Donoghue as Lacie Barone — Taylor’s sorority sister who enters the friend group dynamics (Wikipedia)
• Zoé de Grand’Maison as Agnes — Conrad’s medical student friend, introducing professional-world stakes (Wikipedia)
• Emma Ishta as Kayleigh — Adam’s secretary, adding corporate intrigue to the Fisher family business (Wikipedia)
• Tanner Zagarino as Redbird — Jeremiah’s fraternity brother who re-enters the social circle (Wikipedia)
• Brant Brantley as Young Jeremiah Fisher — portraying the character in flashback sequences that fill in backstory (Wikipedia)

What this means for viewers is that season 3 deliberately expands outward from romance into career and family-of-origin territories—the venture capital firm, the medical world, and the college campus all become new dramatic arenas.

Cast of The Summer I Turned Pretty Benito

Searches for “Benito” in connection with The Summer I Turned Pretty appear in related-query data, though specific casting details for this character remain limited in official sources. The show’s expanding ensemble means minor characters introduced in later seasons sometimes generate viewer curiosity even without full biographical information.

Role Details

• Character name “Benito” appears in cast search suggestions, suggesting viewer interest in a supporting role (Wikipedia)
• No official character description or actor attribution was found in the primary sources reviewed for this article

The implication: if Benito is indeed a season 3 character, he likely falls into the expanded friend-group or college-world category that the show introduced in its final season. Full credits from IMDb would clarify the role details.

Cast of The Summer I Turned Pretty Agnes

Agnes stands out as one of the more clearly defined new additions in season 3, with a specific professional identity that sets her apart from the primarily romantic and family roles that dominated earlier seasons.

Role Details

• Zoé de Grand’Maison plays Agnes, a medical student friend of Conrad who appears in season 3 (Wikipedia)
• The character functions as a window into Conrad’s post-college life, showing a different version of professional maturity than the venture capital world (Cosmopolitan)

The trade-off: Agnes’s introduction creates a subtle romantic possibility for Conrad that contrasts with his history with Belly, though the show ultimately keeps the focus on the Belly-Jeremiah pairing as the season’s emotional anchor.
