“The Summer I Turned Pretty” season one concludes with a beach scene in Cousins, where Conrad confesses his feelings for Belly and they share a kiss set to Taylor Swift’s “This Love.” However, the TV adaptation’s ending differs from the book, as Conrad pulls away from Belly in the original story due to his mother’s cancer relapse. The book’s ending features a December flashback where Belly embarks on a car ride with a mystery boy, likely either Conrad or Jeremiah, heading to their shared beach house. As season two of the show aligns with the second book, “It’s Not Summer Without You,” there are two potential endings to anticipate, each based on different events in the story.
In the potential ending of the second season of “The Summer I Turned Pretty,” based on the events of the second book, we might witness Belly finally moving on from Conrad. The season takes place after the death of Conrad and Jeremiah’s mother, and Belly’s efforts will likely revolve around convincing adults not to sell the magical house in Cousins. The final scenes could depict Belly, Jeremiah, and Conrad waiting out the rain in a hotel room during a road trip. Conrad, feeling bitter after witnessing a kiss between Jeremiah and Belly, apologizes to her for neglecting their relationship. However, in the morning, Conrad’s inability to make eye contact leads Belly to believe that he truly doesn’t care about her. This moment might prompt Belly to make a firm decision to let go of her love for Conrad forever, holding hands with Jeremiah during their car ride home, as depicted in “It’s Not Summer Without You.
If the second season of “The Summer I Turned Pretty” follows the book’s flash-forward ending, Belly may conclude the season in a white dress alongside a mysterious man on the beach. Jenny Han, the creator of both the books and the TV series, could opt to remain faithful to the original conclusion. The flash-forward takes place “a couple of years later” and presents Belly in a white dress, running in the rain towards a car with the mystery man opening the passenger door. When asked if she’s sure, Belly responds with a “no,” leaving her future uncertain and leaving viewers on a cliffhanger. The second season, premiering its first three episodes on Prime Video, holds the potential for this intriguing ending.
