According to Deadline, Prime Video has revealed the final episode rollout for Season Three of The Summer I Turned Pretty. The third and final season, based on Jenny Han (To All the Boys I’ve Loved Before, XO, Kitty)’s best-selling trilogy, will premiere a new episode every week on Wednesdays, following the premiere of two episodes up until the series finale on September 17. 

Season Three will put an end to Belly’s back-and-forth love story between the Fisher brothers Conrad and Jeremiah in the span of 11 episodes. Lola Tung (I Know What You Did Last Summer) will star as Belly Conklin, Christopher Briney (Mean Girls, Dalíland) as Conrad, Gavin Casalegno (The Vampire Diaries, Queen of the Ring) as Jeremiah, Sean Kaufman (Manifest, City World) as Belly’s older brother Steven, and Rain Spencer (Good Girl Jane) as Belly’s best friend Taylor Jewell. Additionally, Jackie Chung (Station 19, Coming Home Again) will play Belly and Steven’s mother Laurel, via Deadline. 

The first season dropped on Prime Video in the summer of 2022, and then the following summer, Season Two premiered with three episodes and then shifted to one episode per week, Deadline notes. 

From what is known as of the two released trailers, there will be many scenes surrounding Belly and Jeremiah dating at Finch University, the college they both attend. Taylor Swift’s “Daylight” plays over the montages of them participating in the classic college lifestyle together. At the end of Season Two, Belly made the choice between brothers after having dated Conrad for several months, Deadline adds. 

Deadline states that the second trailer teases the climactic event from Han’s final book in the trilogy, We’ll Always Have Summer: Belly and Jeremiah’s wedding. However, their announcement is met with much uncertainty from Belly’s mom. In the teaser trailer, Conrad walks into the Cousins Beach house with a candy cane in his mouth and Taylor Swift’s “Red (Taylor’s Version)” playing in the background, interrupting some Belly and Jeremiah lovey-dovey moments. As of now, the series posters place emphasis on all three primary colors, first yellow, then red, and now blue. 

Jenny Han and Sarah Kucserka (Big Shot, High Fidelity) are the showrunners, as well as executive producers. Other executive producers include Paul Lee (Mare of Easttown, Bodkin), Karen Rosenfelt (Max, Wonder Park), Hope Hartman (Book Club, The Lifeguards), and Mads Hansen (End of Watch, Now You See Me) of wiip. Amazon MGM Studios and wiip are producing the series, as mentioned by Deadline.
