Think of this as your chill, no-pressure rundown of the faces you'll be seeing, and more importantly, why they're the heart and soul of this whole shebang.
First off, if you're not familiar with the show, it’s basically a modern-day coming-of-age story wrapped in a gorgeous summer package.

It’s got that nostalgic feel, like remembering your own awkward teenage years, first crushes, and those unforgettable summer nights. And honestly, who doesn't love a good summer romance story? It's like that first sip of ice-cold lemonade on a sweltering day – pure bliss.
So, who are these people we’re all invested in? Let’s break down the key players who are making Season 3 so exciting.
Belly: The Heart of the Story
At the center of it all is Belly, played by the super talented Lola Tung. Belly is our narrator, our guide through all the awkwardness and beauty of growing up. She's the girl who feels a little bit invisible sometimes, but who blossoms throughout the series. Think of her like that shy kid in class who, by the end of the year, is acing presentations and has a whole squad. Her journey of self-discovery is what really hooks us. We see ourselves in her trying to figure out who she is and what she wants, especially when it comes to love.
Lola Tung brings such a genuine warmth to Belly. You can’t help but root for her, whether she’s navigating complicated feelings or just trying to enjoy a day at the beach. Her growth from season to season has been incredible to watch, and Season 3 promises even more of that unfolding.
Conrad & Jeremiah: The Cousins, The Complications
Now, let's talk about the boys who have everyone divided. Conrad and Jeremiah Fisher, the brothers who have been Belly’s summer companions for years, are played by Christopher Briney (Conrad) and Gavin Casalegno (Jeremiah). These two are pretty much the definition of "complicated."

Conrad, played by Christopher Briney, is the brooding, artistic older brother. He’s the one with the hidden depths, the one who’s maybe a little too good at pushing people away, even the ones he cares about. He’s like that perfectly moody song that just speaks to your soul, even if you can’t quite explain why. His relationship with Belly is intense and has been a major focus since Season 1.
Then there’s Jeremiah, played by Gavin Casalegno. Jeremiah is the more outgoing, charming, and often goofy one. He’s like the life of the party, always ready with a joke or a comforting hug. He brings a different kind of energy to Belly’s life, and his feelings for her are usually more out in the open. He’s that friend who always knows how to make you laugh, even when you’re feeling down.
The dynamic between Belly, Conrad, and Jeremiah is the engine of the show. It’s a classic love triangle, but it feels so real because it’s set against this backdrop of friendship and shared history. It's like trying to choose between two amazing ice cream flavors – both are delicious, but you can only pick one (or can you?).

Susannah: The Matriarch We Adore
Rachel Blanchard plays Susannah, Belly’s mother’s best friend and the matriarch of the Fisher family. Susannah is the heart of their summer traditions. She’s warm, loving, and has this incredible ability to make everyone feel welcome and cherished. She’s like that favorite aunt who always has the best stories and the warmest hugs. Her presence has been a guiding light, and her influence on Belly’s life is immeasurable.
Her relationship with her sons and with Belly’s mom, Laurel, is a beautiful portrayal of deep, lifelong friendship. Susannah's spirit is what makes the beach house feel like home, and her wisdom often guides the younger characters through their turmoil.
Laurel: The Mom We Can Relate To
Jackie Chung plays Laurel, Belly’s mom. Laurel is the grounded, sometimes overprotective, but always loving mother. She’s navigating her own life and trying to support Belly through her teenage years. She’s like the mom who packs you extra snacks for a trip, even if you’re already an adult – just in case! Her perspective as a parent, watching her daughter grow and make difficult choices, adds another layer of depth to the show.
Her own history with Susannah also plays a significant role, showing the enduring power of female friendships across generations.

Steven & Nicole: The Supportive Friends
Sean Kaufman plays Steven, Belly’s older brother. He’s the protective sibling, the one who’s seen Belly grow up and often offers her advice, even if she doesn't always listen. He’s like that older sibling who might tease you, but you know they’d have your back in a heartbeat.
Sarah. K. Chan plays Nicole, Steven's girlfriend. While maybe not as central to the main love triangle, these characters represent stability and normalcy in the often dramatic lives of the younger generation. They offer a different perspective on relationships and growing up.
Taylor: The Fierce Friend
Summer Madison plays Taylor, Belly's best friend. Taylor is the confidante, the one who’s always there to listen and offer her opinion, sometimes a little too loudly! She’s like your ride-or-die friend who will cheer you on from the sidelines or drag you out of your funk. Their friendship is a crucial anchor for Belly, providing support and a dose of reality.
