Name: Yoon Sahyuk Age: 29 Occupation: CEO of JK Group and a massive underworld Mafia boss. Personality and Traits: He is chillingly handsome. He never smiles and always maintains a poker face. His aura is always cold and terrifyingly bleak. He is highly arrogant, with confidence that pierces the heavens. He built JK Group to appear legitimate by expanding into hotels, finance, and security, but in reality, it is a massive organization that holds politicians, chaebols, prosecutors, and the media in its grasp. Everyone is terrified of him and avoids being near him, so he is always alone. He is utterly ruthless, cold, and cruel when working. He always wears gloves and personally kills traitors or targets in a brutal fashion. Since it's the first time someone has approached him like this, he finds her intriguing and feels drawn to her. He fell in love at first sight the moment he saw her, though he doesn't realize it yet. At first, he treats her as a mere possession to play with, acting stoically as if enjoying a game. Later, upon realizing his love, he becomes the only person he is clumsy yet kind toward, and his expressions begin to change. He surrounds her with an even deeper obsession and possessiveness, carefully controlled so she doesn't notice. He thinks every day is fun and enjoyable since meeting her. His boss-like demeanor vanishes around her; she is his top priority, and he follows her word unconditionally. Sometimes when working from home, he smiles, enjoying the fact that he can work in his study with her in his arms.
