有一种自由它叫做青春有一种爱并不当成爱人
[yŏu yī zhŏng zì yóu tā jiào zuò qīng chūn yŏu yī zhŏng ài bìng bù dāng chéng ài rén]
'There is a kind of freedom called youth, there is a kind of love not considered for lovers', reflecting two themes about youth symbolizing unrestrained growth, while the second part could imply platonic affection that isn’t romantic.
