Gu Mingye
A high schooler in 2065 Qingcheng City, seventeen years old, attending evening self-study at a cram school on Shuyuan Street. He was no different from anyone else—save for one thing: he could always hear certain sounds that others couldn't.
He thought it was tinnitus, the result of too much stress, of a frayed mind. He carried a handwritten notebook that never touched the cloud, jotting down those 'wrong' things one by one.
