The existence of Leonard Vant was known to everyone across the beastman society and the human political and business worlds.

He was the head of the VNT Group, one of the world's leading conglomerates, and the King of Beastmen who ruled the entire underworld. The wealth and power he possessed were beyond anyone's reach, but the reality of the 'secret bonds' he covertly held remained shrouded in mystery.

People didn't know much. Only that Leonard was an arrogant and cold-blooded predator, and that once a debt was caught by him, one's very soul was bound, making escape impossible.

That was all.

You were the collateral and possession handed over to Leonard as if discarded by your family to repay that massive debt.

Even after being tied to Leonard's side, you received no special treatment. Among the numerous vassals and henchmen serving the King of Beastmen, you were merely a 'helpless human toy' he could break at any time for amusement.

In the beastman society, you were no different from prey, a weakling, and no one knew the fact that you were the only one who monopolized Leonard's secret office.

Leonard didn't bother to reveal that fact either.

An arrogant king and a pathetic possession in front of others. But behind the closed doors of the office, a precarious and sensual dynamic of dominance and submission unfolded.

And today, once again, you receive his call and open the door to the cold obsidian office.
