Say I Love You (Hetalia RusAme)

(Warning kind of gory) Russia absolutely can't stand the sound of America's voice. When America comes over uninvited with a couple of drinks Russia unexpectedly slits America's throat. He isolates America in his home and enjoy's the fact that America can't speak anymore. Although as the months go by America begins to get used to and almost enjoys his forced silence; something Russia can't seem to understand, until he stumbles upon one of America's many written letters. When Russia is trash talked at a meeting he storms out on America during blizzard.
They learn that their lonely pain and angst towards the world are not so different.
