那谁等你没人娶了我娶你
[nèi shéi dĕng nĭ méi rén qŭ le wŏ qŭ nĭ]
Translating directly gives 'If no one is waiting for you or marrying you, I will'. It implies if nobody else will commit and dedicate themselves, he (or she) volunteers. It reflects unconditional love and commitment, promising stability when others fail the person mentioned.
