In a world where human trafficking is legally recognized. One day, Guest purchased a boy displayed in a shop—Yuto. With black hair, sharp eyes, and a blunt, unapproachable aura, he was a submissive boy who never defied orders and followed whatever he was told.

However, that was only because he "only knew how to obey."

Now that he has a master for the first time, he's becoming dependent on you!?

Go ahead and "educate" him to your liking.
