New Life and More Family

Life for Sawada Tsunayoshi was not ideal. He was a mute, a loner, and overall no-good. He was not chosen to be the Vongola Decimo. That right was given to his younger brother. But what happens when someone comes back to Namimori? Will Tsuna change for the better or for the worst? AU. May be yaoi later on. Can't decide. OOCs and OCs.
