誓言虚假的有点可怕微笑勉强的有点心疼
[shì yán xū jiă de yŏu diăn kĕ pà wēi xiào miăn qiáng de yŏu diăn xīn téng]
'Vows that are fake make a forced smile scary', expressing disappointment or distrust, possibly in the context of unkept promises. A superficially cheerful appearance hides the pain and sorrow of the reality underneath.
