The 11-Episode Breakdown: Recapping the *We'll Always Have Summer* Adaptation

Season 3, which premiered on Prime Video on July 16, 2025, and concluded on September 17, 2025, spanned 11 episodes—a slight increase from previous seasons—to fully capture the complexity of the final book. The season meticulously followed the emotional beats of the source material, *We'll Always Have Summer*, while adding new elements to keep the story fresh and unpredictable for even the most dedicated book fans.

The Love Triangle's Final Stand

The central conflict revolved around Belly’s engagement to Jeremiah, a decision made in the throes of post-high school uncertainty and an attempt to cling to the past. The initial episodes set up the impending doom of this relationship, as the emotional distance between Belly and Jeremiah grew, exacerbated by the lingering presence of Conrad.

The biggest twist that deviated slightly from the book was the setting for the final confrontation. Instead of Belly studying abroad in Spain, the series sent her and Conrad to Paris, France, for a dramatic, rain-soaked encounter. This change provided a beautiful, cinematic backdrop for their long-awaited reconciliation. In the series finale, after a painful but necessary breakup with Jeremiah, Belly and Conrad finally find their way back to each other, a moment that fans of the "Team Conrad" camp had been waiting for since the first episode. This resolution confirmed the canonical ending of the trilogy, solidifying the Belly and Conrad love story as the series' defining relationship.

The final episodes revealed that their venture secured crucial seed funding, but the catch was that Steven had to move to San Francisco. This new career path and geographical separation put immense pressure on his relationship with Taylor, who was still navigating her own future. The ambiguity of their ending left many fans wondering if their relationship could survive the distance and the demands of Steven's new life.
