In The Summer I Turned Pretty Season 3, the story picks up at the end of Belly’s junior year of college, with her seemingly settled in a relationship with Jeremiah and already planning their summer at Cousins Beach. However, her life takes unexpected turns when fateful events reintroduce Conrad into her world, forcing her to choose which brother has her heart.

The eleven-episode season, which is based on Jenny Han's book We'll Always Have Summer, features a time jump that depicts Jeremiah and Belly's relationship as it is strained by distance and personal development. The acceptance of Belly to study abroad in Paris, which she is hesitant to accept, and Conrad's difficulties with his medical internship are important story aspects. There are family conflicts as Jeremiah experiences academic failures and Steven is involved in a terrible vehicle accident.

In Episode 10, Conrad pens heartfelt letters to Belly, who is living in Paris. At last, she answers, giving hope for a reconciliation. At the conclusion of the penultimate episode, Conrad makes the hasty decision to travel to Paris, suggesting a potential reunion shortly before the September 17, 2025, finale.
