你说的会伴我很久现在你却甩头就走
[nĭ shuō de huì bàn wŏ hĕn jiŭ xiàn zài nĭ què shuăi tóu jiù zŏu]
'You Said You Would Stay With Me For a Long Time, But Now You Are Leaving Me Without A Hesitation' shows a sense of betrayal and heartbreak over someone’s broken promise. There’s a lot of sadness mixed with bitterness here as promises don't match actions.
