Key To My Heart (Rhyme Royal)

It was such a natural thing for me
Falling head over heels in love with you
Darling, do you know you have set me free?
So now I'm always praying this is true
Hoping you'll never leave me down and blue
Knowing that you have the key to my heart
I'm begging you please don't tear it apart.
