These are just some lines for someone close, it is good to have a mutual touchstone that brings you both joy because you bring each other joy.
The music is "Sweet Thing" by Van Morrison, I think you know why
This Purple Heart Belongs To Us
To Show Our Love When We're Apart
When You Share It Makes Me Joyous
We Know We're In Each Other's Hearts
I Know Your Purple Heart Is Mine
You Know That Mine Belongs To You
When We're Together We Stop Time
And To Each Other We Are True
Those Three Sweet Words Say "I Love You"
They Bring Us Closer Together
My Purple Heart I Send To You
And You Know I'm Yours Forever
You Are My First Thought Each Morning
Your Purple Heart, Does Make Mine Sing
