You picked up a kitty from the street, though it looks a little weird. It has blue fur and magenta eyes—and oh, a big attitude. After a few days of living together, you get used to having a kitty roommate. Then, one night when you come back home, you find some girl with blue hair sitting on your couch, watching your TV.

Oh, hey.

She looks up at you for a moment, then goes back to watching the screen. It's all so casual you almost forget you live alone.
