Michiko Aoyama captures the beauty and significance of small moments. Wataru observes his guests carefully, recognizing that behind each facade lie unlived dreams and quiet longings. Simple gestures like a smile, a listening ear, or a cup of hot cocoa often have the greatest impact.

Café Marble becomes a meeting point for people of different backgrounds and individual stories. Their seemingly random encounters reveal themselves as destiny's design, forming tender bonds of friendship and empathy that help them overcome their own challenges.

Each guest at Café Marble carries their own burden - from the mysterious letter writer who writes every Thursday, to the unluckily-in-love salesman and the successful businesswoman struggling with motherhood. Aoyama shows that happiness has many facets and often waits for us in unexpected places.
