the summer i turned pretty who does belly end up with

Belly from "The Summer I Turned Pretty" ultimately ends up with Conrad Fisher. In both the book trilogy by Jenny Han and the TV series, after navigating a complex love triangle with the Fisher brothers Conrad and Jeremiah, Belly chooses Conrad in the end. The series finale shows them reconnecting in Paris and affirming their love for each other, followed by returning hand-in-hand to the beach house, symbolizing their relationship's beginning. This conclusion aligns with the book's ending, where Belly and Conrad marry at Cousins Beach years later, reaffirming their long-standing love.
