Between Frequencies and Wind is a quiet literary tale about waiting, loss, and the voices that remain after people are gone.

In a small secondhand bookshop by the sea, Han Yura closes every night in the same careful ritual: she locks the door, dusts the shelves, and leaves a worn copy of The Little Prince by the window—as if the sound of a page turning in the wind could prove the room is still alive.

One night, she finds a note hidden between its pages:

If you open this page at midnight, I will begin preparing to let you go.

Soon, a man starts showing up near midnight, carrying the trace of rain with him. His name is Kang Dogyeom, a former late-night radio host who once held sleepless strangers together with his voice. He, too, has lived for years with something he could never fully release.

As Yura and Dogyeom cautiously draw closer, an old name resurfaces—along with forgotten messages, a sealed envelope, and a voice saved for the future. What begins as a small mystery inside a book becomes a tender story about grief, memory, borrowed words, and the courage to stop waiting.

Lyrical and deeply human, Between Frequencies and Wind is an adult fable about the hour when silence changes shape—when midnight is no longer the beginning of longing, but the first step toward letting go.
