The story of The Summer I Turned Pretty seemed to wrap up with season three, but Jenny Han and Prime Video had one last surprise: a movie that promises to finally close out one of streaming’s most talked-about love triangles. Belly, Conrad, and Jeremiah are coming back to the screen, and fans online are already in overdrive with hundreds of theories.
Details are still under wraps, but that hasn’t stopped speculation from running wild — from wedding bells to secret illnesses. The film was officially announced during the red carpet for the season finale in Paris and is set to be the final chapter in a story that’s captured millions of viewers since 2022.
Jenny Han confirmed that there’s still a “big milestone” ahead for Belly in Paris, sparking even more fan predictions. Could it be a wedding with Conrad? A shocking twist with Jeremiah? Or will Belly walk away from both and choose a new path?
One of the biggest theories is that the movie will end with Belly and Conrad tying the knot. The idea lines up with the epilogue of the original book, plus some leaked TikTok clips showing Lola Tung and Christopher Briney filming what looks like a proposal scene in Paris. That said, Jenny Han has already reminded fans that fake scenes were filmed to keep the season three plot a mystery — so nothing is guaranteed.
The finale even rolls into the credits with Christmas photos of the couple in the city of love, which has sparked a new theory: could the movie actually be a holiday special with a romantic twist?
Jenny Han has teased that the film will center on a “major event” in Belly’s life in Paris, and a proposal would definitely fit that bill. Still, not everyone is buying it. Some fans argue that ending would feel way too predictable — and that Han might be holding back something deeper and more unexpected.
Another theory gaining traction is that Belly will finally put herself first. After years of indecision, fans believe she could step away from the love triangle once and for all. This idea connects with the personal growth she showed throughout season three and her need to break free from the Fisher brothers. According to this take, Belly might decide to stay in Paris, focus on her career, and carve out her own path. It would be an empowering ending that would resonate with young viewers — but it would also leave #TeamConrad heartbroken.
One of the darker theories making the rounds online is that Conrad might actually be struggling with an illness. Fans have noticed scenes where he shows pain in his hands and moments of disorientation, which some interpret as signs of an undisclosed medical condition.
This could explain his erratic behavior and add a heavy emotional layer to the finale. Could the movie take this route and show Belly standing by him through a crisis?
Often seen as the “third wheel,” Jeremiah could be holding the key to a major plot twist. Some fans think he might spark an unexpected turn — from a new romance to an emotional betrayal that pushes Belly to make a drastic choice. Others speculate we could finally see a real reconciliation between the brothers, or even a heartbreaking farewell where the youngest Fisher steps away from Belly for good.
The Summer I Turned Pretty movie doesn’t have a release date yet, but it’s already fueling massive buzz across social media. With Jenny Han steering the story and fans more active than ever, this final chapter promises to be as emotional as it is unpredictable. Whether it ends in a wedding, a breakup, or a dramatic twist, one thing’s for sure: Belly, Conrad, and Jeremiah’s story isn’t over just yet.
