Why me? (Sonadow)

Shadow has always hated Sonic's guts. His stupid face, stupid smile, stupid voice, stupid everything! He's always been nothing but a pain. How could he be so carefree and relaxed all the time when it feels as if all of Mobius relies on him? Shadow struggles to find peace as he has constant nightmares and thoughts of his past. He lost his only purpose, Why was he even here? Why did he have to be created if all he's ever brought is pain and suffering to those he loves? Things start to change after his friends force him to stop fighting with Sonic for the good of the team. Shadow and Sonic are as different as can be...but is that really so bad?
