说好的不离不弃只是童言无
[shuō hăo de bù lí bù qì zhĭ shì tóng yán wú]
The phrase can be translated as 'promises to never leave and never abandon were just childish words without true meaning.' This indicates the disillusionment with past promises or commitments, possibly implying that those promises were made during childhood and hence not taken seriously then. It carries a tinge of regret and lost innocence.
