Belly has loved Conrad for a lifetime it seems, but he’s kept his feelings to himself, choosing not to do anything to change their dynamic. After the summer she turns 16, they give their relationship a try, but amid family drama and Susannah passing away, Conrad pulls away and tells Belly to be with Jeremiah instead.
In the final book, “We’ll Always Have Summer,” Belly and Jeremiah become a serious couple and even go to the same college. When Belly discovers he hooked up with someone else while they were on a break, she breaks up with him. He begs her to take him back and proposes, to which she agrees, much to her family’s chagrin. They plan for their wedding to be at Susannah’s beach home at Cousins, but when Belly finds out Conrad is living there, old feelings begin to resurface and she realizes he’s always been the one.
Belly and Jeremiah call it quits, and she studies abroad in Spain, where she starts getting letters from Conrad. They eventually become a couple again, and the book ends with a torrential downpour on their wedding day as they jump into the ocean in their tux and gown.
