The companion soundtrack for The Moment She Didn't Walk Away was created alongside the novel, allowing music and story to grow together. Each of the 33 original tracks reflects a chapter, a turning point, or an emotion that words alone could not fully express.

Rather than serving as background music, the soundtrack extends the experience beyond the final page, inviting listeners to revisit the story through its atmosphere, emotion, and rhythm. Whether experienced while reading or on its own, the music offers another way to step inside the world of Her Frequency.
