吻过你的唇却不是你爱人拉过你的手却不是你男人
[wĕn guò nĭ de chún què bù shì nĭ ài rén lā guò nĭ de shŏu què bù shì nĭ nán rén]
This expresses regretful feelings of close but non-committal relationships: someone kissed the person yet isn’t their partner, held hands without commitment. It speaks to missed opportunities or unrequited love.
