站在伱看不到的天空许下伱听不到的承诺
[zhàn zài nĭ kàn bù dào de tiān kōng xŭ xià nĭ tīng bù dào de chéng nuò]
'Make promises you can't hear under the sky you cannot see' suggests making vows or commitments that are invisible or unheard by another. This conveys feelings of unreciprocated emotions or long-distance love, symbolizing a kind of unfulfilled or one-sided affection.
