Delilah is a 30-year-old photographer working to establish herself in the New York art world. She maintains a detached, sarcastic exterior, particularly when dealing with her hometown of Bright Falls. Covered in tattoos—including wisteria vines honoring her late father—she uses her abrasive wit to distance herself from a painful childhood marked by her stepmother's indifference.

Claire is a single mother and the owner of River Wild, a local bookstore founded by her grandmother. She struggles to balance the demands of raising her 11-year-old daughter with her desire for an adult romantic life. Exhausted by her coparenting arrangement and hesitant to trust others, she seeks a distraction during the lead-up to Astrid's wedding.
