Taipei Late Night Radio

A late-night radio program "Zero:00" can only be listened to on a specific frequency (FM99.9). The host calls himself "Old K" and never shows up. After listeners call in to share their troubles, strange stories, and secrets, strange things will happen - someone disappears, someone gets their wish fulfilled, and someone sees "someone who shouldn't exist." The protagonist accidentally becomes the "last listener" of this radio station, and gradually discovers that there is a larger supernatural network behind the radio station.
