自导自演那虚伪的微笑自导自演那肆意的心动
[zì dăo zì yăn nèi xū wĕi de wēi xiào zì dăo zì yăn nèi sì yì de xīn dòng]
Directing and performing the false smile, directing and performing the spontaneous heart flutter. This conveys the act of pretending happiness while experiencing sincere emotions inwardly, perhaps masking one's true feelings.
