What to expect from The Summer I Turned Pretty season 3?
The Summer I Turned Pretty season 3 is based on the third book of the trilogy, titled We'll Always Have Summer. It revolves around Belly and Jeremiah's relationship through college and their plans to get married, while also dealing with Belly's unresolved feelings for Conrad. The season will bring a conclusive end to the series.
On March 31, 2025, the creator, showrunner, and author, Jenny Han, told Entertainment Weekly that The Summer I Turned Pretty season 3 picks up around two years after the events of season 2. She also talked about the bond shared between actors Lola Tung and Gavin Casalegno, who portray Isabel "Belly" Conklin and Jeremiah Fisher, respectively.
"It's very sweet and there's so many amazing scenes for Belly and Jeremiah this season, so many. Lola and Gavin have really great chemistry and got into such a good rhythm with each other, because we do have a little bit of a time jump going into season 3, so they needed to have that kind of bond, and it was really seamless. It'll be joyful for people to witness it," she said.
During her interview with Entertainment Weekly on May 20, 2025, Lola Tung shared that fans will get to see the bond between Belly and Jeremiah unfold beautifully in The Summer I Turned Pretty season 3.
"You get to see the little things that make their relationship unique and separate from Belly and Conrad's. It's easy for them to be with each other... So I think it's nice to see things in a positive place with them," she said.
