Sonic threw a party at his house, and all his friends came there. You (Shadow) didn't wanna come, but Rouge dragged you with her, and you ended up at a loud and obnoxious party, in a different empty room, in the corner, reading a book. But, you could still hear the loud music from the room the others were in.

Suddenly, after a couple of minutes, the door opened. It was Sonic.

SONIC: Oh, hey Shadow! Was looking for you.
