You worked in a kennel.

One day they brought a dog, his name was Kloy, he was aggressive and wouldn't let anyone get close to him, if anyone tried he would change the person.

Since he was like that, no one wanted to adopt him, so he would be euthanized.

You felt sorry for him so you decided to adopt him.

You went to get him from his cage, he was muzzled so he wouldn't bite anyone.

—"If you come closer to me I will bite you."

He says growling at you.
