The burning question plaguing fans of The Summer I Turned Pretty is whether Belly Conklin (played by Lola Tung) will choose her first love or the man who captured her heart later on. This beloved Prime Video series, inspired by the bestselling books penned by Jenny Han, chronicles Belly’s journey from her teenage years into her college life. As we dive into the highly anticipated third and final season, the suspense builds around one central question: Who will Belly ultimately be with — Jeremiah Fisher or Conrad Fisher?

The characters of Jeremiah and Conrad Fisher are brought to life by actors Gavin Casalegno and Christopher Briney, respectively. Their performances have captivated audiences and added depth to the complex relationships portrayed in the series.

Since the adaptation of the series has diverged from the original storyline of the books, Hollywood Life is here to provide you with all the juicy spoilers and insights about what to expect in the thrilling season 3 of TSITP. (Warning: spoilers about The Summer I Turned Pretty are ahead)

Understanding Jeremiah’s Cheating: What Were His Motives?

The circumstances surrounding Jeremiah’s decision to cheat on Belly are rooted in a complex misunderstanding. Essentially, it all boils down to differing perspectives; Jeremiah believed their relationship was over, while Belly thought they were merely on a temporary break. Fans of Friends might recall a similar situation involving Ross Geller, who famously struggled to define what a “break” truly meant to him. This conflict highlights the intricate emotions and miscommunications that often occur in relationships.

Examining the Frequency of Jeremiah’s Infidelity Towards Belly

When it comes to infidelity, the portrayals of Jeremiah’s actions vary between the original books and the TV adaptation. Within the novels, he cheats on Belly only once, but the television series takes a more dramatic approach, showcasing his betrayal twice. This increase in instances of cheating adds layers to his character and raises the stakes for his relationship with Belly.

Exploring the Age Difference Between Jeremiah and Belly

In terms of age, Jeremiah is approximately one year older than Belly. As depicted in season 3, he is 22 years old while Belly is still 21. Reflecting on their earlier interactions, we recall meeting Belly at just 15 years old, eagerly anticipating her 16th birthday, which adds a layer of nostalgia to their evolving relationship.

Discovering the Age Gap Between Conrad and Belly

Conrad, on the other hand, is about two years older than Belly. By the time we reach season 3, Conrad has turned 23, while Belly remains 21. This age difference contributes to the dynamics of their relationship, influencing their perspectives and decisions throughout the series.

Will Belly and Jeremiah Tie the Knot? Insights from Season 3

In an unexpected twist during season 3, episode 2, Jeremiah proposes to Belly after a brief separation. To everyone’s surprise, Belly accepts his proposal, signaling a potential wedding on the horizon in the TV series. However, with the season still unfolding, viewers are left in suspense as to whether this engagement will lead to marriage or if other plot developments will alter their course.

According to the storyline in the third book, titled We’ll Always Have Summer, Belly and Jeremiah do not end up getting married, although they come very close. Just days before their planned wedding, Conrad overhears Jeremiah’s friends discussing his past romantic involvement with Lacie during a bachelor party. This revelation prompts Conrad to confess his lingering feelings for Belly, urging her not to proceed with marrying Jeremiah.

The escalating tension leads to a confrontation between Jeremiah and Conrad, during which Jeremiah admits he recognizes that he may never be Belly’s first choice. Ultimately, this realization results in the cancellation of the wedding and the dissolution of Jeremiah and Belly’s relationship.

Unraveling Belly’s Fate in the Summer I Turned Pretty Book Series

In the original book series, Belly’s journey concludes with her choosing Conrad. Their love story culminates in marriage a few years after Belly embarks on a study abroad adventure in Europe. The two maintain their connection through heartfelt letters, and at her college graduation, Belly reunites with Conrad, realizing he is her true love. Eventually, at the age of 23, Belly marries Conrad at Cousins Beach, reminiscent of their childhood escapades as they run off into the ocean together.

What to Expect: Belly’s Journey in the TV Show

If the Prime Video adaptation remains true to the original plot of the books, then Belly is destined to end up with Conrad. However, it’s worth noting that the TV series has taken creative liberties, diverging from the source material in significant ways. Fans have observed various differences that could dramatically alter the outcome of the story.

In June 2022, Jenny Han, the author and creator of the Prime Video series, shared insights with Variety regarding her creative vision for the adaptation. She emphasized that her intentions for the show might differ from the narrative established in her books.

“I really had to weigh what the fans are expecting with where the show is going creatively and find that balance,” Jenny explained. “My priority has always been to ensure that fans of the book feel satisfied with the story we’re telling, while also understanding that this is an adaptation in a new medium, so it won’t be identical.”

Jenny hinted at the potential for unexpected twists, stating, “You never know what could happen with the show. I was open-minded going into it. I considered a variety of different possibilities.”

Season 3 Episode Count: What Fans Can Anticipate

Fans can look forward to a total of 11 episodes in season 3 of TSITP. The highly anticipated season finale is scheduled to air on September 17, 2025, promising to deliver climactic moments and resolutions to the beloved characters’ stories.
