如果说爱情已不会回来如果说回来已不是爱情
[rú guŏ shuō ài qíng yĭ bù huì huí lái rú guŏ shuō huí lái yĭ bù shì ài qíng]
Translated to 'If love does not return, or if it returns, it's not the same love anymore'. It expresses a sense of sorrow after losing genuine love and implies the understanding that even if what seems lost can be returned, it may have changed. Perhaps the user had once fallen deep in love but was deeply hurt.
