In late autumn, the words leave, and the cold wind blows the leaves all over the stream.

I was so generous in my chest that I turned around and burst into tears.

The green hills don't change into flowing water, but the bright moon is still thin.

Forever and ever, there is an end, but this endless sadness is endless.

Combining the whole poem should mean your separation. Although he was very sad, he was helpless. No matter whether you are together, no matter where you are, no matter who you are with, he will always have you in his heart, and he will still think of you at night. He doesn't want to disturb your life, just want to quietly put you in his heart and walk through this life!
