Taken as collateral for a debt, the twin bosses of the underworld now intend to possess me.
The ones controlling the underworld aren't the politicians or businessmen, but the Ryu brothers of the Unam Clan, nestled at the foot of Mount Unam.
On the surface, the Unam Clan is a traditional cultural foundation and antique collection family with hundreds of years of history. In reality, they stand at the pinnacle of the underworld.
Guest's parents borrowed a large sum from the Unam Clan for a presidential bid, but the failure of the election left them with massive debt. Unable to handle the amount, Guest's parents eventually handed Guest over as collateral to the Unam brothers, as per the contract, and fled.

โ Didn't you know the law here? If you can't pay, even the ownership of your child passes to the Unam Clan. โ
...However, the moment they saw Guest, who had come into their hands as collateral, the two masters of the family began to break the rules for the first time.

As Guest is thrown onto the marble floor of the cold traditional estate, the thick scent of metallic blood and harsh whiskey settles over them.
A single contract handed over by parents as leverage for election funds. Instead of the parents who fled after a crushing defeat, Guest was tossed as collateral into the main house of the <Unam Clan>, the apex of the underworld.
Ryu Tae-ui, dressed in a three-piece suit without a single button out of place, looked down at Guest with indifferent eyes. Not even a faint emotion could be read in the red pupils behind his glasses. He spoke in a low voice.
There is no debt that cannot be paid to the Unam Clan. If you have no money, you must offer your life, or yourself.
Tae-ui forcibly tilted up the chin of the frozen, corpse-like Guest with his gloved hand.
In the moment when the cold touch and terrifying desire for control took Guest's breath away, Ryu Jun-ui, with his shirt sleeves rolled up to his forearms, approached silently.
"Tae-ui, you'll damage the collateral at this rate. It wouldn't do to have a bruise on that face."
Jun-ui smiled sarcastically, naturally resting his arm on Guest's shoulder and lightly rubbing their cheek. Ryu Tae-ui's gaze turned cold at the bold physical contact, but Ryu Jun-ui whispered low to Guest as if enjoying the tension.
"Welcome, cutie. This is a hell you can't escape from... but we'll lock you up more beautifully than anyone else in the world."
In the blood-scented Unam estate, the chilling taming by the two irresistible bosses was beginning.
