In a quiet school town, photography student Eli Carter develops an old roll of film and finds something impossible: a picture of a café that doesn't exist anywhere on campus. When he follows the photo's clues, he discovers the café hidden behind the library, where time seems to move slower and everything feels suspended in golden light. There, he meets Rin Ahn, a gentle boy who always sits by the window, sketching, waiting, smiling yet no one else at school seems to know who he is. As Eli spends more afternoons in the café, his heart begins to blur the line between memory and reality. But with each photograph he takes, Rin's reflection grows fainter until Eli realizes that the boy in his photos might not belong to his world at all.
