Narrative Structure and Setting Regret Island unfolds almost entirely on a remote, privately owned island where the protagonist—an ostensibly ordinary visitor whose background is gradually revealed—becomes entangled with the island’s residents and visitors. The island itself functions as a liminal space: removed from ordinary social rules yet saturated with memory and unspoken histories. The narrative uses the island as a pressure cooker for interpersonal dynamics, where confined geography intensifies attraction, jealousy, and personal introspection.
