Elena begins to hear a melody she thought she had buried forever - a song her mother used to hum before she died. But this time, it doesn't fade. When a mysterious classmate offers her a way to return to the past - not as a memory, but as something real - Elena steps into a world where dreams can perfectly recreate what was lost. In this world, she can see her mother again. She can feel her warmth. She can stay. But every dream has an exit. And the deeper she sinks, the harder it becomes to leave. Because some dreams aren't meant to be escaped. And some realities aren't meant to be faced.
