只为你一个人溃不成军
[zhĭ wéi nĭ yī gè rén kuì bù chéng jūn]
'Falling apart for only you'. The phrase signifies complete devotion and the vulnerability that comes from giving your whole heart. But 'falling apart' could also represent the destruction one suffers after dedicating all of themselves to someone who didn't value them, reflecting intense feelings and possibly subsequent suffering and defeat.
