A girl loses her way in a forest and finds a ghost boy she can never touch. That single rule becomes the entire story, and it breaks you. The film doesn't rush, it watches them grow into the weight of that distance, and by the time you understand what the ending means, you're crying over a choice that was made the moment they met.

On a summer visit to her grandfather's house, six-year-old Hotaru gets lost in a forest said to belong to a mountain god and to be home to spirits. A masked boy named Gin comes to help her, but he pushes her away when she tries to hug him. A curse means any human touch will make him vanish forever. Gin tells her not to come back, yet Hotaru keeps returning, and the two become close friends. As the years go by and their feelings for each other grow, they struggle with the limits fate has placed between them. The film is a supernatural fantasy romance with a strong dramatic core.
