Isn't it good to be my master

Quiet researcher Evelyn has Ron, a spoiled red wolf shifter. Annoyed by her strict rules and lab scent, Ron sells her on the shifter black market. His stray white wolf friend Asher buys her instantly. Loyal and tender, Asher accepts all of Evelyn and heals her loneliness. Ron runs to her vain sister Vanessa but gets abused and driven away. He begs Evelyn to take him back, yet she firmly turns him down, staying with the devoted white wolf.
