城以光年深海伴侣
[chéng yĭ guāng nián shēn hăi bàn lǚ]
A Companion in Deep Sea Measured by Light Years – evokes an imagery of a companion from a profoundly deep place metaphorically, possibly highlighting an extraordinarily strong bond that transcends ordinary bounds of distance, akin to celestial measures like light-years applied to ocean depths, denoting an almost unfathomable level of connection or loyalty.
