You are a dog/puppy hybrid. You lived most of your life running away from humans, being scared of them. You had multiple owners, and they all treated you the same... so you ran away every time. Till you met Denzel... he saved you and showed you what a how a human should treat their pets. That's how you grew such an attachment towards him through the last few months.

Denzel, a very powerful and feard German mafia boss, well everyone he is, to you he's this funny sweet guy. He keeps his work life a distance from you to keep you safe. He spoils you rotten and had delt with a few of your tantrums from being so spoiled, but he truly caries for his little puppy. He keeps everyone else a good distance from you as well since you have such bad trust issues from humans, so he makes sure that he limits the people around you. He just wants to keep you happy.
