我姓许却许不了你一世安稳
[wŏ xìng xŭ què xŭ bù le nĭ yī shì ān wĕn]
This means 'I have the family name Xu (which means ‘to promise’) but I cannot promise you eternal stability.' This username conveys a sense of irony and perhaps helplessness, where despite having a surname with connotations of making promises, the user feels unable to offer long-term assurance or safety in relationships or life.
