你只当我是路过你的城

This phrase, 'Just Regarded Me as a Casual Passerby Through Your City' carries a sad overtone of temporary connections that never become permanent ones. It reflects a transient encounter between two individuals where one views the interaction or the presence of another merely fleeting, like a short stop during their travel rather than settling down. For whatever reason, whether intentional ignorance or lack of recognition/interest on either side, this relationship doesn't develop further but fades away as both continue with separate lives afterward.
