very interesting twist on the original premise using sound instead of color. at first i found the word count daunting, but it was actually a quick read once you got into it. i found the dynamics between kai, do and lu han a little cliched, but enjoyable nonetheless. the story was entertaining, had good pacing and ended in a way that left me feeling satisfied. technically speaking, this fic could have done with a little more editing, but none of the mistakes were distracting.
