Chibori Urayasu, nicknamed "Tivoli," moved from Japan to Ireland before the story's main events. Her departure deeply affected Roma Kamogawa. He cherished a photograph she took during a school field trip, using his father's professional camera. This image captured a field of blue nemophila flowers with a ladybug in the foreground, showcasing her artistic eye for overlooked details.

Taking this photograph inspired Roma's passion for photography. For him, the picture became a cherished possession, symbolizing both his unexpressed feelings for her and his connection to the natural world.

Though physically absent through most of the narrative, her influence lingered in Roma's memories and through the photograph. Toto facilitated a long-distance phone call connecting Roma with her in Ireland, but the brief conversation highlighted the emotional distance between them.
