In August, both Elsie Fisher and Kyra Sedgwick were confirmed to sign on with new roles for the second season.
"We get to create this whole new person," the Eighth Grade actress previously told E! News. "Part of what really drew me to the project is that I get to play a person that still feels very true to myself, but is different from the kind of character people have seen me play before."
Production for the second season began last July, with Belly (Lola Tung), Conrad (Christopher Briney) and Jeremiah (Gavin Casalegno) all returning.
Additionally, Steven (Sean Kaufman) and Taylor (Rain Spencer) are also among the familiar faces back at Cousins Beach.
Creator Jenny Han teased the differences fans should expect between the book and the series, especially for season two. "There's always gonna be changes here and there," she told E! News in December. "So I guess you'll just have to wait and see."
As the season's synopsis promises, the love triangle between Belly, Jeremiah and Conrad didn't just come to a screeching halt in season one: "Belly used to count down the days until she could return to Cousins Beach, but with Conrad and Jeremiah fighting over her heart and the return of Susannah's cancer, she's not sure summer will ever be the same."
That said, Conrad and Belly seem to have an intimate moment or two.
...And the same could easily be said for Belly and Jeremiah.
After season one, Tung shared her outlook for her character's journey the following summer.
"I'm very excited to see the trajectory of Belly's relationship with both of the boys and with everyone in her life," she exclusively told E! News in June 2022. "She can only continue to grow and to go on this journey and I'm very excited to go on it with her."
Casalegno also shared how hopeful he was about their latest chapter together.
"It's something so special to be able to look forward to how a book was written and trying to translate that into a series," he told E! News, "and also fit it in with the changes that were made for season one from book one. I'm excited to see how it plays out, genuinely."
