我愿自尽也不让你伤
[wŏ yuàn zì jĭn yĕ bù ràng nĭ shāng]
'I'd rather take my own life than let you be hurt.' This username conveys extreme protectiveness or devotion towards someone else, usually romantic or family oriented, demonstrating willingness for making huge sacrifice. Note this kind of expression should be viewed as rhetorical flourish rather than practical advice.
