别用你吻她的嘴说爱我别用你说爱她的嘴吻我
[bié yòng nĭ wĕn tā de zuĭ shuō ài wŏ bié yòng nĭ shuō ài tā de zuĭ wĕn wŏ]
'Don't use the lips that kissed her to profess love to me, nor use those same lips that tell her 'I love you' to kiss me.' This line exposes the pain felt from unfaithfulness and disloyalty in relationships, showing deep hurt due to betrayed trust.
