我在等某一天你娶我我在等某一天你嫁我
[wŏ zài dĕng mŏu yī tiān nĭ qŭ wŏ wŏ zài dĕng mŏu yī tiān nĭ jià wŏ]
'I am waiting for the day when you marry me / I am waiting for the day when you marry me' conveys a hopeful or bittersweet anticipation of a long-term commitment from a loved one—expressing desire for marriage, which could suggest a current unreciprocated sentiment.
