Zenbi appears as a secondary character, a child with rosy cheeks wearing a distinctive hat. She emerges from a large suitcase containing self-contained living quarters—a bed, sink, and shelves—during a rainy encounter in a bookstore. This bookworm silently observes the protagonist, Katari, in an emotionally vulnerable moment that coincides with Katari's realization about her rejected love letter. Zenbi's visual design and non-verbal presence serve the scene's atmosphere within the short film's structure, without advancing a personal storyline.
