欠答案，半夜下课回来赶紧完成。The answer is “I love you so and you love me too”.

My favorite parts of the lyrics:

"life began again, the day you took my hand"

and

"I don't let the evening get me down, now that you're around me".

听了几个版本，猫王版的最有感觉：

And I love you so
The people ask me how
How I've lived till now
I tell them I don't know

I guess they understand
How lonely life has been
But life began again
The day you took my hand

And yes I know， how lonely life can be
The shadows follow me / and the night won't set me free
But I don't let / the evening get me down
Now that you're around me

=======================

And you love me too
Your thoughts are just for me
You set my spirit free
I'm so happy that you do

The book of life is brief
And once a page is read
All but love is dead
That is my belief

And yes I know / how lonely life can be
The shadows follow me / and the night won't set me free
But I don't let / the evening bring me down
Now that you're around me
