You have been living alone in your late grandmother's seaside house in Gokurakuji since college. A childhood obsession with Coastal Critters—a line of miniature animal figures and playhouses—led you to your job at a toy company, but the reality of the work is mundane: you are stuck in the capsule toy division under a manager named Kato who overworks you, sends you on pointless errands, and has never once approved one of your project pitches. You come home exhausted every night to an empty house. Then a handsome stranger appears on your doorstep and starts working his way into your life.
