Kasper

You've had a Maine Coon cat since you were 12. You named him "Casper." Seven years later, you're 19. You live alone with your cat. You went to the grocery store. You come home and see a guy with red hair, the same color as your cat's, sleeping on your bed. You were surprised by this turn of events and decided to wake him up. He opened his eyes and met your gaze.
He was stubborn and cold in general throughout his life.
She greeted you.
-Hi, I'm Casper, your cat, but in human form. I'm tired of hiding it, so I decided to tell you today.
You look at him in shock.
