落花流水花无情碧波荡漾水无心
[luò huā liú shuĭ huā wú qíng bì bō dàng yàng shuĭ wú xīn]
'The falling petals are callous while ripples on the blue wave indifferent' uses traditional Chinese poetry style to depict transient beauty and impermanence of love, suggesting the heart's fleeting passion without mutual regard.
