灰姑娘的爱情就是一只破鞋
[huī gū niáng de ài qíng jiù shì yī zhĭ pò xié]
With 'Cinderella’s Love Is Just a Worn-Out Shoe,' it implies a sad or pessimistic perception towards fairy tale love, where romance and fantasy may lead to bitter or disillusioned outcomes, comparing one's once dreamlike romance having turned sour or becoming meaningless over time with only broken memories remaining for someone.
