我姓万却挽留不住你的心
[wŏ xìng wàn què wăn liú bù zhù nĭ de xīn]
'Though my family name is Wan (meaning myriad/10 thousand), your heart was never truly captured by me.' Reflects the pain of loving deeply but being ultimately left behind. The use of 'Wan' playfully ties into the expression of endless efforts in vain.
