The love triangle that has captivated a generation is coming to an emotional close. In the newly released trailer for the third and final season of The Summer I Turned Pretty, fans are getting a first look at Belly’s next chapter — which includes a surprising engagement, the return of old feelings, and the high-stakes decision that will define her future.
A long-awaited return to Cousins Beach
After two seasons of teenage longing, sun-drenched heartbreak, and the iconic Team Conrad vs. Team Jeremiah debate, The Summer I Turned Pretty is heading toward its final destination. The new trailer for the third and final season, which premieres July 16 on Prime Video, reveals that everything is coming to a head — and it’s all happening with a time jump, a college setting, and a wedding on the horizon.
The footage opens with Belly (Lola Tung) and Jeremiah (Gavin Casalegno) looking blissfully in love, now navigating life as a couple in college. Their sweet moments play against a melancholic narration from Belly, as she reflects on her journey from youthful crushes to adult love. “First loves are important,” she says, while Taylor Swift’s “Red (Taylor’s Version)” transitions into “Daylight” — a musical nod to the emotional journey ahead. “But they’re not as important as lasts.” But the real shocker comes midway through the trailer: Belly is engaged — to Jeremiah.
A wedding, a past love, and a storm ahead
While Belly and Jeremiah seem happy and secure in their relationship, there’s one unresolved thread that refuses to stay in the past: Conrad Fisher (Christopher Briney), Belly’s first love and the original root of her heart’s confusion. Now living on the West Coast, Conrad opens up to someone about Belly still being the only girl he’s ever loved. Meanwhile, Belly insists to herself that Conrad is “the past,” and Jeremiah is “the one.”

But as fate would have it, all three are soon back at Cousins Beach — the site of so many of their most formative moments — and the trailer teases that it’s there where things will unravel and intensify. Belly is faced with emotions she thought she’d buried, and the love triangle that once defined her teenage summers now threatens her adult future.
The synopsis confirms that the season begins during the summer following Belly’s junior year of college — a departure from Jenny Han’s original novel We’ll Always Have Summer, which took place earlier in the characters’ lives. This shift not only allows the characters to age with their audience but adds a layer of maturity and gravity to the decisions they now face.
A love triangle with no easy answer
Jenny Han, who serves as both the original author and showrunner, has long promised fans that the final season will contain twists — and some departures from the source material. “There are surprises,” Han teased in a previous interview. “And there are things that aren’t exactly like the books.” For devoted readers and newcomers alike, that means no one can predict how the love story will end.
What is clear, however, is that the central love triangle remains the emotional core of the series. And Han is acutely aware of the impact it has had on viewers. “I feel like I’m doing my job if people are really fighting for their sides,” she told Entertainment Weekly, referring to the often passionate debates between Team Conrad and Team Jeremiah fans. “A successful love triangle is one where, no matter what happens, people are going to be devastated and heartbroken.”
It’s a sentiment echoed in the trailer’s visual and emotional cues — longing stares, tense confrontations, tearful glances — all building toward a moment when Belly must finally choose between the two brothers who have each shaped different parts of her life.
The road to a satisfying goodbye
The final season’s weekly episode release format suggests Prime Video wants viewers to live in this emotional world a little longer — and perhaps argue about it a little more. With the wedding looming and feelings resurfacing, each episode will peel back the layers of Belly’s decision and what it ultimately means for her, Jeremiah, and Conrad.
Han has also hinted that her goal with the ending is to bring closure while respecting the emotional complexity of all three main characters. “If the answer feels really clear and easy, then there’s no real conflict,” she said. “No matter what you do, someone’s going to be hurt by it.”
That raw honesty is what has always made The Summer I Turned Pretty resonate. More than a romantic fantasy, it’s a coming-of-age story about love, grief, identity, and the bittersweet passage from youth into adulthood. And as the series approaches its conclusion, it seems ready to honor all of that — even if it breaks a few hearts along the way.
The final season of The Summer I Turned Pretty premieres July 16 on Prime Video, with new episodes released weekly.
