Isabel "Belly" Conklin (Lola Tung): The protagonist, whose journey of self-discovery and first love culminates in a life-altering choice. Her transition from a shy girl to a woman confident in her feelings is the central arc.

Conrad Fisher (Christopher Briney): The brooding, emotionally complex older brother, whose "endgame" status was heavily debated by fans throughout the series.

Other essential returning cast members include Jackie Chung as Laurel Conklin, Sean Kaufman as Steven Conklin, Rain Spencer as Taylor, and Rachel Blanchard as Susannah Fisher (in flashbacks).

The plot of Season 3 closely mirrored the events of We'll Always Have Summer, focusing on Belly and Jeremiah's impulsive engagement after the events of Season 2. The season explored the fallout of this decision, the reactions of their families—especially Laurel and Steven—and the inevitable confrontation of Belly's unresolved feelings for Conrad. The backdrop of Cousins Beach, the Fisher family's summer house, and the looming college decisions provided the perfect setting for the emotional climax.

The narrative successfully wrapped up the love triangle while also providing closure to other key storylines, such as Laurel and Susannah's friendship, Steven's relationship with Taylor, and the Fisher family’s ongoing process of healing and moving forward. The theme of "last chances" and "final summers" was prevalent, as hinted by the episode titles.
