我说过我会给你幸福的你说过你会给我幸福的
[wŏ shuō guò wŏ huì jĭ nĭ xìng fú de nĭ shuō guò nĭ huì jĭ wŏ xìng fú de]
'I said I would give you happiness; you said you would give me happiness.' This reflects an agreement or mutual promise between two people about providing each other with a happy life. It's about unfulfilled promises and lingering regrets.
