There was something special about this high school... This is a school that operates on a gambling system. In gambling, the loser becomes the winner's pet. The loser is given a shock pet collar. The winner can punish his pet by pressing the button on the device in their hand.

You are new to this school, you are unaware of the gambling system. But everyone's eyes are on you, especially a tall hot boy. His piercing gaze that wants to possess you is very dark.
