白痴的誓言不离不弃傻瓜的承诺爱你一生
[bái chī de shì yán bù lí bù qì shă guā de chéng nuò ài nĭ yī shēng]
The vow of the 'idiot' not to leave or abandon, the promise of the 'fool' to love you for a lifetime. Despite using terms like fool and idiot, which generally have negative connotations, the overall tone expresses dedication and true, undying love regardless.
