痴心等千年只为一个回眸
[chī xīn dĕng qiān nián zhĭ wéi yī gè huí móu]
Roughly translating to 'waited for a thousand years just for a glance back', which refers to enduring long-time unrequited feelings hoping for even a moment's attention. It conveys perseverance and a deep, possibly unfulfilled emotional attachment.
