In both the books and the TV show storyline, Jeremiah does not end up with Belly; she ultimately chooses Conrad instead.

Quick Scoop: Who Does Jeremiah End Up With?

In Jenny Han’s book trilogy, Jeremiah and Belly actually get engaged for a while, but the relationship falls apart before they can marry, and Belly later marries Conrad. Jeremiah shows up at Belly and Conrad’s wedding with a date, suggesting he’s moved on and hinting at an off‑page future romance, but the books don’t lock him into a clear, named “endgame” partner.

In the Prime Video series, by the time of the series finale, Belly is again clearly endgame with Conrad, and Jeremiah’s story shifts toward finding happiness away from the love triangle. On screen, he begins to get his own arc, stepping into his career and opening the door to a new romance instead of staying stuck on Belly.

Show Ending: Jeremiah’s “New Path”

In later-season coverage and finale breakdowns, Jeremiah is shown growing into his own person, with a focus on cooking and becoming an up‑and‑coming chef/food influencer. Commentary on the finale explains that this growth ties into him letting go of Cousins and the old Belly‑Conrad‑Jeremiah dynamic and finally getting emotional closure.

The show sets up a new love interest for Jeremiah named Denise, a co‑worker/friend who supports his ambitions and challenges his insecurities. Their connection builds over time and culminates in Jeremiah taking the leap and kissing her, which she reciprocates, strongly implying that Denise is his romantic future in the series universe.

Fandom & Forum Talk

Fan discussions and forum threads have long debated “Team Jeremiah” vs “Team Conrad,” but even many Jeremiah‑leaning viewers accept that the core story is structured around Belly and Conrad as endgame. Reddit and other forums often describe a hypothetical Jeremiah–Belly ending as changing the message of the story, suggesting it would shift the theme toward “the nice, safe choice” rather than the deeper, more complicated first love that Belly has with Conrad.

At the same time, many fans appreciate that the show does more work than the books to give Jeremiah a satisfying independent ending—career growth, emotional closure, and a fresh, healthier relationship—rather than leaving him as just “the one Belly didn’t pick.”

TL;DR: In The Summer I Turned Pretty , Jeremiah does not end up with Belly; she ends up with Conrad, while Jeremiah moves on—books leave his future relatively open, but the series points him toward a new romance (Denise) and his own happy ending.
