我害怕有一天你离我而去抛弃全世界也不会丢了你
[wŏ hài pà yŏu yī tiān nĭ lí wŏ ér qù pāo qì quán shì jiè yĕ bù huì diū le nĭ]
A poetic expression that roughly translates into 'I'm afraid that one day you will leave me, abandon the world, but I wouldn't lose you'. It shows a very deep, unconditional attachment towards someone.
