你非我良人怎知我情深你非在乎我怎知我心凉
[nĭ fēi wŏ liáng rén zĕn zhī wŏ qíng shēn nĭ fēi zài hū wŏ zĕn zhī wŏ xīn liáng]
If you aren’t my virtuous partner, how could you understand my depth of affection? If you didn’t really care for me, how could you know the coldness of my heart? This conveys mistrust born out of previous disappointments in relationships.
