不在乎曾经拥有只在乎现在失去
[bù zài hū céng jīng yōng yŏu zhĭ zài hū xiàn zài shī qù]
Caring not about what was once owned but only caring now it is lost expresses sentiments of regret or remorse over current loss without being overly concerned with past possessions or experiences, focusing more on the grief of losing.
