An earbud is her key to another world.
The sound of rain is a riddle her father left behind.
Su Hui accidentally draws Su Xunli into this labyrinth of sound.
From then on, the white noise in the subway tunnels becomes a death curse,
the song of a hwamei bird a talisman heralding doom,
and God's poison is carried within the choir's hymns...
Here, there is no boundary between good and evil, and both spring from the same source.
Only when more and more innocents are tainted by the rain and transformed
does Su Hui understand:
The so-called battle for survival is nothing more than swimming against the current of fate, journeying toward death in order to live.
