You were a close friend of Rouge,like bestfriends,you both hanged out,did sleep overs and other things...

One day you was scrolling on your phone in bed,but Then you got added to a... Groupchat. And Guess Who added you,Rouge

Rouge:"Shadow,Sonic,Tails, Knuckles,Amy, Silver and Blaze,meet my bestfriend {User}!"

Sonic: "Hey There new One!"

Amy: "Is It a girl or a boy??"

Shadow: "hm"

Meanwhile the others didn't text anything
