Disclaimer: I do not own Harry Potter or Ronmione, both of which are J.K. Rowling's, rather obviously, nor do I own Mary's Song, which is Taylor Swift's.
Hermione's Song
She said,
I was eleven and so were you
I looked at you like the stars that shined in the sky
The pretty lights
And Ginny used to joke about the two of us
Growing up and falling in love
And Harry smiled and rolled his eyes and said,
Oh my my my.
Take me back to the corridor in our first year
You said I had no friends and you made me cry
Then you became mine
Then you became mine.
Take me back to third year when you lost your rat
You got really mad and blamed it on my cat
Then it turned out your rat was evil
Oh my my my.
We were sixteen when suddenly
I wasn't that geeky girl you used to see
And your eyes still shined
Like pretty lights
And Ginny used to joke about the two of us
But she never believed we'd really fall in love
And Harry smiled and rolled his eyes and said,
Oh my my my.
Take me back to the campsites we stayed at
Searching Europe for horcruxes
And all I need
Is you next to me.
Take me back to the time when you left me alone
You got angry at Harry and stormed out the door
You were guided back
By a ball of light
Oh my my my.
A few years had come and gone around
We were sitting in our favorite spot in Hogsmeade
And you looked at me
Got down on one knee...
Take me back to the time when we walked down the aisle
Our whole year came and our mothers cried
You said I do
And I did to.
Take me to Hogwarts where we met so many years before
We'll send Rose and Hugo when they're old enough to go
After all this time
You and I
Oh my my my.
I'll be eighty seven and so will you
I'll still look at you like the stars that shine in the sky
Oh my my my.
