我一转身你就永远离开了
[wŏ yī zhuăn shēn nĭ jiù yŏng yuăn lí kāi le]
'When I turned around, you were gone forever.' This implies deep sorrow or longing from an irrecoverable parting. In a broader context, it can also symbolize lost opportunities or unreciprocated feelings, reflecting sadness at missing something meaningful suddenly.
