不知这场错过会不会是一生
[bù zhī zhè chăng cuò guò huì bù huì shì yī shēng]
In English, this would mean 'I don't know if this missed encounter will be a lifetime'. It conveys profound regret and reflection about a chance that was missed which could lead to permanent separation or lost chances in love or friendship, possibly due to miscommunication or bad timing.
