Teens by Blood, Soldiers by Association.

They say that music saves lives. I live by that theory. This is the story of how one teen introduced a friend into the fandom.

This story is set within the world of Shingeki No Kyojin (Attack On Titan), but with the modern technology of phones, computers, and mp3 players.

Yes, this is kinda a LevixEren fanfic. Shut up and deal.
The only true differences are the phones, the music, and Levi and Eren are both females...
