After a lifetime of being bad at love, JoJo Burton vows to solve her intimacy issues once and for all at her sister’s destination wedding on a cruise ship. Armed with pop psychology, she diagnoses herself with a fixation on the neighborhood guy who was her first crush and first kiss (and who just happens to be a newly divorced wedding guest). Determined to woo him for closure, she ropes in her childhood bestie, Cooper Watts, as her wingman. Cooper: who RSVPed no but showed up anyway. Cooper: who moved to London without a word four years ago. Cooper: who broke her heart.
