A quiet high school girl with a broken heart, Aika drifts through her days like a ghost — unseen, untouched. Until one day, a mysterious student appears: Himeko. Beautiful. Gentle. Strange… and dangerously attentive.

An intoxicating bond begins to form between them. But as Aika unravels, her view of the world shifts. The amusement park of her childhood — once bright and full of joy — now seems faded, abandoned… just like her. And in those forgotten ruins, hidden from everyone else, Himeko is waiting.

How much would you give to be truly loved… forever?
