The only thing that came to mind was Nebo and Kiara's song lol...well I think its fitting for them. The Sweetest Thing by U2. I bolded the lines that make me think of those two the most.

My love she throws me like a rubber ball
Oh, the sweetest thing
She won't catch me, or break my fall
Oh, the sweetest thing
Baby's got blue skies up ahead
But in this I'm a rain cloud
You know she wants a dry kind of love
Oh, the sweetest thing

I'm losing you, I'm losing you
Ain't love the sweetest thing?

I wanted to run but she made me crawl
Oh, the sweetest thing
Eternal fire, she turned me to straw
Oh, the sweetest thing
I know I got black eyes, but they burned so brightly for her
Guess it's a blind kind of love
Oh, the sweetest thing

I'm losing you, I'm losing you
Ain't love the sweetest thing? Ain't love the sweetest thing?

Blue eyed boy meets a brown-eyed girl
Oh, the sweetest thing
You can sew it up, but you still see the tear
Oh, the sweetest thing

Baby's got blue skies up ahead
But in this I'm a rain cloud
Ours is a stormy kind of love
Oh, the sweetest thing
The sweetest thing
The sweetest thing
