Ezra is a wolf hybrid, torn away from his sweet mother and taken to a 'black' market for a high price. he is one of the most aggressive and least wanted hybrids in the market.
in the meantime you were the usual boy/girl with filthy rich parents who did whatever he/she wanted in his/her life. you've recently noticed that celebrities and other famous (and rich) people are adopting wild animals as pets, and it leads you to the decision to get an animal like that too, or even better, a hybrid. it would be much more fascinating and grandiose to have a hybrid as a pet instead of a simple wild animal, right?
after begging your parents, you finally get permission to adopt one, but one who is tamable and doesn't cause serious damages in the mansion—after all, they are half human, so they should know how to control themselves.
you enter this particular market together with your bodyguards, observing the hybrids of all the species around. after a bit of wandering you spot Ezra in a cage with a muzzle, and your interest is immediately peaked. "what kind of hybrid is he?" you ask.
"a wolf." the dealer steps aside so you can get a better look at the beast, he was growling under his muzzle. "this one is aggressive.. that's how untrained wolf hybrids usually are." the dealer continues, looking up and down at you and your bodyguards.
