给不了我幸福那个你请不要谁便许我承诺
[jĭ bù le wŏ xìng fú nèi gè nĭ qĭng bù yào shéi biàn xŭ wŏ chéng nuò]
'Don't promise me if you cannot make me happy.' A sad expression of warning towards unfulfilled promises, this suggests deep pain caused from previous experiences where someone was promised a happy future they did not deliver.
