愿得一人心是个童话白首不分离是个笑话
[yuàn dé yī rén xīn shì gè tóng huà bái shŏu bù fēn lí shì gè xiào huà]
'Wishing for the one whom loves only oneself eternally is a fairytale whereas never apart till death do we part is laughable'. It sarcastically reveals that monogamous romance often idealized in fairytales doesn't really exist; the notion that people will be with same partner all through aging process seems unrealistic to them
