Why Season 3 Was the Final Chapter and What’s Next

Many fans were left wondering if there would be a Season 4, especially given the show's massive popularity and the dedicated "Team Conrad" and "Team Jeremiah" fandoms. However, the 11-episode Season 3 was confirmed to be the end of the series.

The show is based on a trilogy of books by author Jenny Han, and Season 3 adapted the final novel, *We’ll Always Have Summer*. Since the source material was fully covered, the show reached its natural conclusion. Showrunner Jenny Han, who also wrote the original books, has always been committed to faithfully adapting the core story and the ending established in the novels. The final episode, "Last Summer," provided a definitive answer to the central love triangle, giving closure to the journey of Belly, Conrad, and Jeremiah.
