知道你的心不在我这里知道你的爱永远在他那
[zhī dào nĭ de xīn bù zài wŏ zhè lĭ zhī dào nĭ de ài yŏng yuăn zài tā nèi]
'I Know Your Heart Is Not Here, I Know Your Love Will Always Be In Him', it shows understanding of someone's lack of interest or feelings toward oneself but instead having feelings for another. It represents a sad recognition of unreciprocated love or acceptance.
