曾经引以为傲的默契曾经信以为真的誓言
[céng jīng yĭn yĭ wéi ào de mò qì céng jīng xìn yĭ wéi zhēn de shì yán]
Roughly translates as 'Proud trust we once held; Oaths we sincerely believed were true', signifying nostalgia about promises and understanding that used to define a relationship which no longer exists. This phrase captures a feeling of lost trust and disillusionment.
