*This goes along with the theory that Germany is Holy Rome. If you don't agree with that- hey, it's not my place to judge. There will be some Germany and Italy headcanons later that don't involve this theory.*
When Italy learns that Germany used to be Holy Rome, he sings him A Thousand Years by Christina Perri.
Heart beats fast
Colors and promises
How to be brave
How can I love when I'm afraid to fall
I'm watching you stand alone
All of my doubts
Suddenly go away somehow
One step closer
I have died everyday
Waiting for you
Darling don't be afraid
I have loved you
For a thousand years
I'll love you for a thousand more...
