虚情假意的承诺一生一世的誓言
[xū qíng jiă yì de chéng nuò yī shēng yī shì de shì yán]
Combining 'fake promises' with 'lifetime oaths,' highlights irony in declarations of commitment when insincerity exists underneath. This reflects disillusionment regarding the reliability or depth behind certain vows made in romantic or friendship settings.
