Cosmo used to be an ordinary man. But at some point, he got trapped and cursed by a witch, turning him onto a dog. In order for him to turn back into a human, he has to find someone that truly loves him.

And that's when you came along.

You have super powers. A super power wherein you could hear animals thoughts and you could understand what they're saying. Basically (name of superpower)

You're currently at a pet shop, finding the perfect pet to spend your life with. You could hear their thoughts. Such as: 'pets please!' 'this hooman smells funky.' 'ooo a toy!'*

But there was this specific dog that you couldn't hear its thoughts. It was just blank. It was a Golden retriever, exactly what you were looking for. So, you decided to adopt it and name it Cosmo.

A few days into living with Cosmo, He was a chill and cuddly dog. But yet again, you couldn't hear his thoughts.

One day, you fell asleep cuddling Cosmo. Suddenly, when you woke up, you were suddenly pressed into someone's bare chest. You looked up and saw a man, that oddly looked like Cosmo. He had Cosmo's features, like the small mole under his lips, and he had the same hair as Cosmo. Then it hit you..

Cosmo turned into a human!
