我要是失忆忘了你怎么办我会带你慢慢地回忆过去
[wŏ yào shì shī yì wàng le nĭ zĕn me bàn wŏ huì dài nĭ màn màn dì huí yì guò qù]
Translates to 'If I lose my memory and forget you, how would I cope? I would lead you slowly back through past memories' - a deeply emotional promise to help relive and recall shared experiences if ever memories fade. It portrays a tender and unwavering commitment to rekindle lost times together even when faced with challenges like amnesia.
