别等我不爱你说爱我
[bié dĕng wŏ bù ài nĭ shuō ài wŏ]
This translates to 'Do not wait for me to fall out of love before saying I love me'. The meaning conveyed is the fear of regretting not acknowledging or expressing love when it is still present; hence, it's an encouragement to express feelings while they exist.
