They have been best friends since as long as they can remember...

Do you remember when I said I'd always be there.
Ever since we were ten, baby.
When we were out on the playground playing pretend.
Didn't know it back then.

They thought nothing would be able to change it

Now I realize you were the only one
It's never too late to show it.
Grow old together,
Have feelings we had before
Back when we were so innocent

He used to take care of her, considered her as a little sister

I pray for all your love
Girl our love is so unreal
I just wanna reach and touch you, squeeze you, somebody pinch me
This is something like a movie
And I dont know how it ends girl
But I fell in love with my Best Friend

Until he realized... she was more than that

Through all the dudes that came by
And all the nights that you'd cry.
Girl I was there right by your side.
How could I tell you I loved you
When you were so happy
With some other guy?

He used to pull pranks on her, made her cry a lot

I know it sounds crazy
That you'd be my baby.
Girl you mean that much to me.

And nothing compares when
We're lighter than air and
We don't wanna come back down.

Until he figured out... he had fallen for her

And I don't wanna ruin what we have
Love is so unpredictable.

But it's the risk that I'm taking, hoping, praying
You'd fall in love with your best friend

She thought she loved him... until the other one changed her mind

I remember when I said I'd always be there
Ever since we were ten baby.
