Official Opening Chapter
The Night Radio's First Noise
At three in the morning, Liang Lan hears her own name in static. The screen shows half a line, 'I am still here,' while the rest is swallowed by snow and only a return symbol blinks; before dawn, the first return line stays on the glass.
Continuation Anchor
The next chapter must continue after the return line stays on the glass, waiting for the next coordinate to bring the half-line back into the channel.
