南岸少年北城少女
[nán àn shăo nián bĕi chéng shăo nǚ]
Translation yields 'Boy From Southern Bank & Girl In Northern City'. By this way, one can feel like there's always distance between them because southern banks versus northern cities, which makes the whole thing sound romantic. The boy and girl might be two different characters or personalities who grow up apart geographically but share something deep inside each other.
