[G] - [D] - [Em] - [C] - [Am]



[G]         [D]
  I cant believe this
[Em]         [C]
Now all my dreams are come true
[G]                       [D]
  Had his kiss and now I'm flying
[Em]                     [C]                      [G]
Im flying through this song which, through and through
                         [D]
Cant believe that I just kissed him
[Em]         [C]           [G]
Everything I want and even more
                         [D]
All this time I have just missed him
[Em]             [C]                  [D]
Now looking in my eyes and through a door


                [D]   
Now that we've come this far
[Em]             [C]
Promise you won't break my heart
[G]                [D]
It took so long to see that 
[Am]           [D]         [G]  ([D] - [Em] - [C]) 
I am yours and you belong to me.
