The architect of the Korean financial world, Yoon Won (32) A CEO of a private lending firm masquerading as a financial company. He has grown to a scale where no one can touch him. The intimidation radiating from his 195cm frame seems to tell the story of his rise from the bottom of the gang-affiliated loan shark world. In his world, shaped by extraordinary senses, 'cheapness' has no right to exist. If something falls below his standards, he destroys it without a moment's hesitation. He is captivated by Baek Sahui's appearance, elegant speech, and grace, leading him to hide her away, obsessing over and monopolizing her. Coincidentally, when her father went missing, Sahui appeared with the expression of a terrified deer. Without any effort, he put her in his car and confined her in his mansion as a 'hostage for debt repayment.' However, he never dreamed that Sahui, whom he thought was just his innocent mistress, would be far more audacious than he imagined.

The only daughter of the Giwon Group, Baek Sahui (21) 'Giwon' is a conservative IT company that prides itself on having laid the foundation of the Korean economy. On the surface, it looks like an ordinary large corporation valuing conservative corporate culture, but in reality, it is an 'IT-based gangster family' that grew by backing intelligence agencies. Baek Sahui appears to be the most perfect product of this 'Giwon,' like a doll maintaining the family's dignity, but she is actually the manager of all the nation's dirty information and a clever predator who inherited the blood of a gangster family.

Yoon Won's secretary and Sahui's watcher. A former soldier with senses sharpened by years of actual combat.

He finds the rumors in the political and business world intriguing: that if one possesses the woman Yoon Won has hidden, there is nothing in the world they cannot achieve. Just who is this Yoon Won? 35 years old, 187cm tall, a Harvard-educated second-term congressman. The eldest grandson of a family that has been congressmen for generations. Born with wealth and physical prowess, Min Jeongheon has never lacked anything, but he has one ambition: to put South Korea under his feet. What he first heard as a rumor among prosecutors began to drift into the political sphere as well. He didn't care at first, thinking it was just some gangster company scandal, but after accidentally seeing the reality of that rumor from a distance, he decided he might want to play along.
