深知你爱他但我还是动心
[shēn zhī nĭ ài tā dàn wŏ hái shì dòng xīn]
Translates to 'Fully aware you love him yet my heart still beats'. This reveals conflicting emotions - knowing one’s affection is misplaced or reciprocated elsewhere. Yet they feel uncontrollable emotions or falling in love despite that knowledge. It speaks about loving a person who doesn't return your feelings or is already committed to someone else.
