The highly anticipated finale of "The Summer I Turned Pretty" Season 3 is set to air on Amazon Prime Video on September 17, 2025. As the series, based on Jenny Han's best-selling trilogy, draws to a close, fans worldwide are on tenterhooks, eager to discover the resolution of the central love triangle involving Belly Conklin and the Fisher brothers, Conrad and Jeremiah.

Season 3 has seen Belly, portrayed by Lola Tung, navigating a complex journey of self-discovery and romantic entanglements. The second-to-last episode found Belly in Paris, attempting to build a life away from Cousins Beach and the Fisher brothers, while also exploring a romantic connection with Benito. However, Conrad's decision to fly to Paris in an attempt to win her back has thrown everything into question.

The finale's central question revolves around Belly's choice: Will she choose Conrad, Jeremiah, or ultimately choose herself? The series has deviated from the books, particularly with Belly's Paris chapter, suggesting a potentially different conclusion. Jenny Han, the author and showrunner, has teased a "non-traditional ending" that will surprise fans and delve deeper into Belly's choices and relationships.

Throughout Season 3, Belly's relationships have been tested. Her engagement to Jeremiah crumbled under the weight of unresolved feelings for Conrad and Jeremiah's own insecurities. Meanwhile, Conrad, who is becoming a doctor and attending therapy, may be on his way to Belly, but Han teases that "he and Belly aren't in the same place".

In episode 10, after calling off her wedding with Jeremiah, Belly moved to Paris to start a new chapter in her life. While in Paris, she befriends Benito and starts a casual relationship with him. On New Year's Eve, after some encouragement from Taylor, Belly kisses Benito, despite the fact that Conrad was still sending her letters. Though Belly is now in Paris and seemingly happy, Conrad decides to fly to Paris to find her.

Ultimately, the finale may see Belly choosing herself. Han has emphasized the importance of finding oneself before entering a relationship. With Belly's journey of self-discovery in Paris, it's possible she may realize that she needs to focus on her own growth and happiness before committing to either Conrad or Jeremiah.

Whether Belly ends up with Conrad, Jeremiah, or chooses herself, the finale promises to be an emotional and unforgettable conclusion to "The Summer I Turned Pretty". The episode will be available on Amazon Prime Video on September 17, 2025, at 3 a.m. ET / 12 a.m. PT.
