Have you ever dreamed of the same dream several times, but can't remember the appearance of that person? She just vaguely remembered the inexplicable peace of mind she felt by his side. She dreamed several times of the person standing in the vast expanse with his back to her. When she decided to uncover the answer, a soul ferry started... She couldn't name her name, couldn't remember her back, what was it like? We are old friends, so we are reunited.
Concept: The person she keeps dreaming about actually means everything
