Keeper

After a lifetime as a free wolf, Kane is kidnapped by a boy named Roman. Soon, he learns why. The boy is involved in underground werewolf fighting, and he wants Kane to battle in a tournament.

Despite being collared, Kane still considers himself a free wolf, and he won't call the boy his keeper. Unfortunately, Roman loathes him for it. Yet as time drags on, feelings change and affection grows.

Kane doesn't want to care for a human who holds him captive, and Roman doesn't want to love a man he sees as an animal.
