For fans of The Summer I Turned Pretty Season 3, there’s been one nagging question hiding in plain sight since the very beginning: Where exactly does Belly live when she’s not pining over Conrad or planning impulsive weddings with Jeremiah at Cousins Beach? Well, the answer has officially arrived, and it’s not just a throwaway line. Belly lives in Philadelphia, Pennsylvania. Not near Cousins. Not in some generic suburb. She’s a Philly girl through and through.
The reveal may not be screamed from the rooftops, but eagle-eyed fans finally got concrete confirmation in The Summer I Turned Pretty Season 3, Episode 4, when Belly sends a heartfelt text to her dad apologizing for leaving Philly without saying goodbye. But the real breadcrumbs date all the way back to Season 1, with background clues that make you want to rewind and scream, “How did I miss that?!”
Turns out, the license plate on Laurel’s car in Season 1, Episode 1 was quietly flashing Pennsylvania pride all along, and a moment in Season 1, Episode 7 all but confirms it when Steven mentions they grew up “in the suburbs of Philly.” It’s classic Summer I Turned Pretty energy: big feelings, soft lighting, and blink-and-you’ll-miss-it details with emotional weight.
Cousins Beach may feel like home, but Philly is where the heart started

Much of The Summer I Turned Pretty Season 3 is set in the beloved (and fictional) Massachusetts beach town of Cousins, where sand, secrets, and seasonal heartbreak go hand in hand. But Belly's connection to Cousins is more emotional than residential; it's her summer escape, not her zip code. While the Fisher brothers hail from Boston, Belly’s true home is several hours away in the City of Brotherly Love.
This distinction matters more than it seems. The entire premise of the series rests on Belly's dual life: the grounded, suburban Philly girl trying to find herself, and the dreamy, barefoot-in-the-sand version who exists at Cousins. The Summer I Turned Pretty Season 3 deepens that contrast by pulling her back into her hometown for pivotal scenes, showing that real life doesn’t pause just because summer romance heats up.
Belly's return to Philadelphia isn't just a pit stop; it’s a wake-up call in The Summer I Turned Pretty Season 3

After the disastrous wedding announcement in Episode 3, Belly's mother, Laurel, does what any mom of a suddenly engaged teenager would do: she hits the brakes hard. By sending Belly back to Philadelphia, she forces her daughter to take a breather from all things romantic and reflect on what really matters. It’s a symbolic reset, trading beach bonfires for concrete sidewalks and emotional chaos for uncomfortable truths.
Belly’s text to her father at the end of Episode 4 may be short, but it says volumes about her inner conflict. She’s torn between her summer world and her real one, and the show wants us to sit in that discomfort with her. As The Summer I Turned Pretty Season 3 continues, expect Philly to become more than just a background location; it’s a mirror to who Belly was before the waves, the boys, and the heartbreak.
