Alpha's Brother Was My Pet

I found an injured werewolf. In my free time, I loved curling up in his soft fur to take a nap. Later, after his injury healed and he shifted back into human form, his eyes glared at me with a fierce warning: "A werewolf only has one mate in their lifetime. I already have a werewolf I like, and I will never accept you." "Keep your filthy thoughts to yourself. I won't like you!" With that, he ran off. I stood frozen, utterly confused. What on earth was he talking about? I had always treated him like a dog—what does that have to do with being mates? ... Later, I bought a big Labrador, took it home, and saw the werewolf squatting at my doorstep, looking pitiful. "You humans are so fickle," he sobbed. "You've abandoned that dog. So, take me instead." "My fur's thicker than his, my coat's denser, I eat less, and I can earn money. All the money I make will go to you." "...If you don't agree, I'll eat that stupid dog you're holding!"
