誓言过后只剩下假话
[shì yán guò hòu zhĭ shèng xià jiă huà]
'誓言过后只剩下假话' (After vows, only lies remain) carries quite heavy negative emotions—it indicates disappointment or cynicism regarding promises or commitments made by either oneself or other individuals that ultimately failed to fulfill. Perhaps reflecting upon betrayed trust or broken promises.
