对不起没有长出你爱的模样
[duì bù qĭ méi yŏu zhăng chū nĭ ài de mó yàng]
Translated from Chinese, 'Duibuqi Meiyou Zhangchu Nihilaimo Yang' roughly means 'Sorry, didn't grow into what you hoped/ expected for.' The username suggests sadness and regret of not meeting expectations, especially those related closely to someone loved.
