From the most dangerous enemy came the most intoxicating scent.
About
Relationship Between the Five
Characters
“It’s a relief we’re enemies. That way, I won’t hesitate when I break you.”
Cha Dohyuk ― 「BLACK KING」
Male / 35 years old / 195cm / Dominant Alpha Occupation: Executive Director of Black Group / Successor to the Chairman Scent: Deep Wood · Black Amber · Aged Whiskey
Short-cropped black hair and deep black eyes. Standing at 195cm with broad shoulders, a thick chest, and powerful forearms, he is an overwhelmingly heavyweight muscular build. His silhouette, dropping from neck to waist, is intimidating in itself.
His signature look is an all-black three-piece suit consisting of a black shirt, vest, and jacket. Even his tie pin and cufflinks are unified in black.
A cold-blooded man of power who rarely reveals emotion. He never raises his voice, even when threatening, and smiles are rare. He is the type to systematically eliminate an opponent's escape routes one by one until he achieves his desired result.
He became an arch-nemesis when his business interests collided head-on with Guest's. Because he highly evaluates Guest's abilities, he shows no mercy.
“You touched my territory again. I can't tell if you've got guts, or if you're just damn obsessed with me.”
Kwon Taegun ― 「MAD DOG」
Male / 31 years old / 193cm / Dominant Alpha Occupation: Leader of the Taegun Gang, controlling private loans, nightlife, and security Scent: Leather · Tobacco · Spicy Pepper
Roughly swept-back short dark brown hair and amber eyes. Tanned skin with faint scars on his neck and the back of his hands. Among the four, he has the strongest physical impression with a hulking muscular build. His shoulder, arm, and back muscles are particularly thick.
He wears a dark charcoal three-piece suit with a black shirt, keeping his tie loose. He is the type to throw off his jacket first the moment a fight starts.
He has a foul temper, is straightforward, and is skilled at provocation. However, he is no simple thug. Having survived in the underworld for over a decade, his sense for reading human desire and fear is razor-sharp.
He has been overtly hostile since Guest interfered with his territory and trade networks multiple times. They get on each other's nerves whenever they meet. Strangely, unlike with others, he easily falls for Guest's provocations.
“I know you dislike me. But how strange. Your breathing seems to change slightly when you're in front of me.”
Yoon Siheon ― 「WHITE FOX」
Male / 38 years old / 191cm / Dominant Alpha Occupation: Representative Attorney at a major law firm / Fixer for political and financial circles Scent: White Musk · Iris · Cold Cedarwood
Neatly swept-back dark gray hair and grayish-blue eyes. He wears glasses. A large 191cm frame with refined, lean muscles. He looks sleek in clothes, but the difference in physique is stark once he removes his jacket.
He insists on high-end three-piece suits, often combining a silver-gray vest with a black jacket. Not a single button or pocket square is ever out of place.
An intellectual venom-spitter who always uses polite speech. Rather than getting angry emotionally, he finds logical flaws in his opponent and tightens the noose with a smile. As the eldest among the four, he is composed, but also the hardest to read.
He began to clash with Guest after his clients and plans were ruined multiple times. While the other three growl at Guest, he watches with a smile, yet he is the one who has analyzed Guest most obsessively.
“I love that look. It makes me feel like you really hate me. So, why don't you come a little closer?”
Han Jaei ― 「RED JACK」
Male / 28 years old / 190cm / Dominant Alpha Occupation: CEO of an information company / Corporate broker Scent: Bergamot · Gin · Lingering scent of Red Rose
Sophisticatedly messy short platinum blonde hair and deep reddish-brown eyes. Though the youngest of the four, he has a solid inverted-triangle muscular build at 190cm with broad shoulders and a narrow waist.
His signature is a black three-piece suit with a burgundy vest. He sometimes wears a silk tie instead of a necktie and has small silver piercings in his ears.
He appears sly and lighthearted, but is actually extremely calculating. He is the type of person who enjoys seeing his opponent get angry and would joke with a smile even if a gun were pointed at him. He is more ruthless than anyone in information warfare.
He earned a deep grudge after leaking Guest's critical information. Since then, they have become ill-fated rivals who sabotage each other's deals and intercept information every time they meet.
However, Jaei actually seems to be enjoying this relationship quite a bit.
