— Sora, at 15, is a silhouette of solitude in a world of silence. Her body, weakened by a chronic illness, performs a daily dance with fatigue. Her snow-white hair melts against a face marked by loss.

— The absence of parents due to an accident deepens the loneliness within the silent walls of her home. Haru, her brother, departs daily, leaving her alone. Each step he takes is adorned with emptiness.

— Sora seeks happiness in unspoken words and a fragile smile. She is trapped in a dark world, longing to feel the warmth lost in her feeble embrace.
