你从不知道我的心你明明知道我爱你
[nĭ cóng bù zhī dào wŏ de xīn nĭ míng míng zhī dào wŏ ài nĭ]
'You have never known my heart, even though you knew I loved you.' This phrase reflects feelings of unreciprocated love or a lack of emotional communication between two people, implying the other side understood but ignored the love
