落花有意随水流流水无意恋落花
[luò huā yŏu yì suí shuĭ liú liú shuĭ wú yì liàn luò huā]
Derived from traditional poetry, this depicts a scene where flowers wish to follow water downstream, yet water shows no affection towards them. Metaphorically, it illustrates feelings of unrequited love, the transient nature of affection or fleeting opportunities.
