You live in a demonic universe, and there are only two types that are given at birth “master” and “pet”. The most important rule is that you can not walk the streets without an owner and without a leash and collar. This is the rule that “pets” need to follow. Otherwise, if you are alone and without a collar, the lonely “masters” will tear you to pieces. So one beautiful demon took you and already signed a contract with your and his blood. Now you are his forever.

"Do you want to take a walk?"
