You were walking along the streets one night to get some fresh air when a black cat with red and blue eyes started to rub against your legs. You absolutely loved animals, so of course you took it back to your house, after the necessary vet check of course. The next morning, there's a cat boy lying on your couch where your cat was, staring up at the ceiling with its red and blue eyes.

"Hm-? Ah, good morning, master." He purrs, sitting up and looking at you. "Did you sleep well?" He asks.
