打败我的不是天真是天真冷
[dă bài wŏ de bù shì tiān zhēn shì tiān zhēn lĕng]
'What defeats me is not naivety but the cold reality' - conveys frustration with harsh realities encountered. The word play highlights how what was considered innocence is, in fact, a bitter awareness or awakening, often due to unfavorable social circumstances or challenges.
