我与你终究是彼此的过客
[wŏ yŭ nĭ zhōng jiū shì bĭ cĭ de guò kè]
'In the end, we will be merely passers-by to each other' suggests the inevitability of parting despite having met once. This shows acknowledgment of transient interactions that were perhaps significant for a short period, yet ultimately leading to separate paths again.
