少了你的时光我寂寞成殇没有我的日子你别来无恙
[shăo le nĭ de shí guāng wŏ jì mò chéng shāng méi yŏu wŏ de rì zi nĭ bié lái wú yàng]
Your absence leaves me lonely; if I am gone, please take care of yourself. It shows a deep attachment to a person and expresses sorrow while also wishing well for someone even after separation.
