Lovers Concerto

Hi guys.
I'm listening to a song, lovers concerto. I will paste here the lyric of the song for you all. I underlined and bolded one sentence that I can't understand its meaning and grammar. Could you help me have an explain for this?

How gentle is the rain
That falls softly on the meadow
Birds high above in the trees
Serenade the flowers with their melodies oh oh oh
See there beyond the hill
The bright colors of the rainbow
Some magic from above
Made this day for us
Just to fall in love
(*)
You'll hold me in your arms
And say once again, you love me
And if your love is true
Everything will be just as wonderful

Now I belong to you
From this day until forever
Just love me tenderly
And I'll give to you every part of me oh oh oh
Don't ever make me cry
Through long lonely nights without love
Be always true to me
Kept it stay in your heart eternally
Someday we shall return to this place upon
The meadow
We'll walk out in the rain
Hear the bird's above sing once again oh oh oh
(Repeat *)

****
Thanks
