不知道我只知道我爱你不记得我只记得我想你
[bù zhī dào wŏ zhĭ zhī dào wŏ ài nĭ bù jì dé wŏ zhĭ jì dé wŏ xiăng nĭ]
'I don't know anything except that I love you, and if I can't remember who I am, all I recall is wanting to think of you.' This shows deep, overwhelming feelings and devotion to someone. It’s an exaggerated statement emphasizing strong emotions.
