A couple whose marriage began with a chance meeting at a karuta club, Yuri and her husband share a deep passion for the traditional card game. Their skill earned them an invitation to study under a legendary karuta master.

Aware of her discomfort, her husband feels pained seeing her distress each time they attend class together, wishing he could ease her embarrassment. Yet this growing anxiety continues to cast a heavy shadow over her experience in the karuta classroom.
