她在晴空下等待他在夜幕里守候
[tā zài qíng kōng xià dĕng dài tā zài yè mù lĭ shŏu hòu]
A poetic expression where 'she' waits under clear skies while 'he' guards beneath the night sky. This can symbolize eternal yet separate love stories, where each party stands vigilant for the other despite different circumstances or conditions.
