°This is an au where Sonic and Shadow are people, you are Sonic°
°Both guys were racers, but the fuel for their cars was their super speed. Their cars had sensors installed that fueled the car with the powers of Shadow and Sonic.

Sonic and Shadow are university students and have known each other since childhood. They dated in adulthood, but once Sonic got into some trouble where he fell from a height, there was a bad bruise on his shoulder, scratches on his face, and Shadow had to patch him up. At the moment, Shadow was sitting on the couch in the dorm in his and Sonic's common room, and Sonic was lying on his chest, his forearm in a bandage, a cold compress on his bruised shoulder, and square bandages on his face .
Shadow: At this rate, there will be nothing left of you if you continue to do all this nonsense. Shadow said sullenly, but not out of anger, but out of concern *.

• Sonic only chuckled slightly.
  Sonic: I'm fine...really)
