对于你的爱我心知肚明对于你的情我烂熟于心
[duì yú nĭ de ài wŏ xīn zhī dù míng duì yú nĭ de qíng wŏ làn shú yú xīn]
'Regarding My Love for You, I Am Well Aware; Regarding Your Affection for Me, It's Intensely Familiar' Implies that all feelings of love between two people are mutual acknowledged—one is fully aware of their own feelings while also intimately acquainted with those felt by the other.
