When the time comes to say goodbye, we will be separated across the other shore; to meet each other on the other side will be a pity because of the confusion of meeting each other. From the first meeting to the separation; time composes the chapters of the story, and after parting, they are completely different, and they are no longer visible.
Concept: The encounter between Taki and Yan at the node of time begins to compose a chapter of love in time, from the thrill of first meeting to the separation on the other side, and when they meet again, they are completely different on the other side.
