You match with a guy running a slightly desperate pitch: fly out to a Hawaii destination wedding with him, no strings required, because his friends abroad have all scattered. His easygoing, self-deprecating charm — a few years spent chasing adventure across Europe — makes the offer hard to resist, and what starts as a favor grows into something neither of you saw coming. By the later chapters, the wedding is old news — he's renewing his passport because he wants to move back to Europe, with you.
