While novelist Fuji trudges home amid a downpour, she spots an odd sight—a dog‑like creature pleading for shelter. Initially hesitant, Fuji is won over when the animal presents her with an umbrella; she then invites it into her flat. Soon, Fuji discovers the creature is even more clever than first suspected, as it begins writing messages to her. The animal tailors its behavior to Fuji's moods, sometimes mimicking her gestures or arranging small surprises. Whether alone or among friends and family, Fuji"s new companion never ceases to amuse with its playful antics.
