I found this song online it's a song made for Harry Styles. They posted the chords so I 
thought why not post it here :)

D - A - Em - G


Verse 1

D          A             Em
You have a lot of pretty girls
G                  D
Screaming for your name
            A
Your a superstar
                   Em
But that's not the reason
                 G              D
I just love you for who you are
                 A
For what you do,
          Em
For being imperfect
                     G
And I want you to know that


Chorus

            D
I love your curly hair,
      A
Your green eyes,
     Em                      G
Your dimples that makes your smile so perfect
    D      A               Em
And I want you to be mine,
    G           D     A
But it's impossible
    Em     G
Impossible


Verse 2

D - A - Em - G
(Same to Verse 1)
We live in two different worlds
And we're thousand miles apart
I'm in love with a guy
Who doesn't even know that I exist
But as long as I could see
That cheeky little grin..(and)

Chorus

            D
I love your curly hair,
      A
Your green eyes,
     Em                      G
Your dimples that makes your smile so perfect
    D      A               Em
And I want you to be mine,
    G           D     A
But it's impossible
    Em     G
Impossible


Bridge

D           A
I know this sounds crazy,
    Em        G
But I will do anything
    D
And everything
A            Em           G
Anything and everything, yeah


(Strum Once)

                D
Just to see that curly hair,
      A
Those green eyes,
          Em                   G
Hear that voice that makes you so damn perfect
D               A            Em
And I know that this will be possible...

I don't know
         D        A
But it's impossible
Em       G
Impossible


Chorus

            D
I love your curly hair,
      A
Your green eyes,
     Em                      G
Your dimples that makes your smile so perfect
    D      A               Em
And I want you to be mine,
    G           D     A
But it's impossible
    Em     G
Impossible
       D
Impossible
