Haruka and Shiina were inseparable from childhood — close enough that both believed it would last forever. Then Haruka broke down. Worn to the bone by a demanding career as a nurse, she quit everything and moved back to her parents' house, convinced she had become a failure. She could not face Shiina. She did not try for almost five years. When Shiina finally reaches her and proposes a spontaneous trip to Dreamy Planet — an old favorite, a theme park outside Nara now left to rust — Haruka agrees. Walking through the ruin of somewhere they once loved, old memories resurface. The park may be beyond saving. Their friendship might not be — if Haruka can find the courage to say what she has been holding back.
