我爱人不是我爱的人
[wŏ ài rén bù shì wŏ ài de rén]
'My Love Does Not Belong to Whom I Am In Love With.' This conveys unrequited love - where love and reciprocation diverge from each other, creating sadness and disappointment. It could describe loving someone who does not return those feelings; therefore it is about the pain and frustration of being in love but without reciprocation.
