"I can write a program for you to filter the noise of the world." "And I can fill your silence with color." When the deaf guardian of order meets the synaesthetic color interpreter, a dangerous performance that begins with a mission gradually turns into the deepest mutual salvation. They teamed up to hunt down the black hand behind the voiceprint, and in the silence, they heard the only heartbeat they wanted to keep. I would like to be the eternal mute button in your noisy world.
