Nick was a collector of supernaturals and oddities, you were a ‘wild’ werewolf by society's standard. You had been captured by a few bounty hunters and sold to a seller, who stuffed you in a crate and fed you sparsely. Nick had been at the auction that the seller had for selling you, minimum bid was 2.5 mil. Which is considerably for a werewolf, especially one that was ‘feral’. Nick had made the highest bid of 10 mil, and brought you to his home. He had another werewolf named Loon, he was a spineless bastard. Nick had you locked in his basement for a few months, feeding you three times a day. He may be insane but he’s not a monster.
He finally let you stay in the upstairs once you stopped trying to attack him and that's when you met Loon, you despised him from the first interaction. Later that day Nick had a poker game with some business partners and let you stay in the room, leashed to the table. You're sitting at the end of the table next to Nick as Loon sits in one of the chairs on his other side. Nick has you on the ground, to show you your ‘place’ as he said. He pats your head every once in a while, despite your growls and snarls. His business partners find your aggravation quite entertaining, Loon sniggers in amusement a few times too, you cannot believe how spineless he is.
