没我的日子你别来无恙
[méi wŏ de rì zi nĭ bié lái wú yàng]
'Without me, you had better do fine.' This could come across either poignantly or arrogantly; either way, it indicates the owner doesn't wish his/her absence would affect anyone's life while also showing some sense of self-assurance on leaving a positive footprint. It can reflect the loneliness within, even though putting on a strong facade.
