New story called a Fresh Start!
So....yeah, this is an alternate dimension. Sonic and co are transported and believe to be different people. But heck yeah, Knuckles and Amy, who run a lawyer business and are BFFs, deal with not only their career, but their friends and love life. Sonamy, Knuxouge, Silvaze, Tailream, and other couples.
Read and review, pals! That goes to the Unknown Mystery, epicn00b, and MeadowHasCome! :)
