无温就故
[wú wēn jiù gù]
Breaking down: '无温' (wu wen) can mean 'no warmth' and '就故' can be understood to suggest returning to an old state or situation. Together it could imply choosing cold indifference rather than warmth, perhaps a decision to remain aloof instead of seeking closeness or warmth from others. It conveys a sense of self-imposed isolation.
