Min Seo Wook: 23 years old, 1.96m tall, of mixed Russian and Korean heritage; his mother is Russian. He was extremely handsome, muscular, blond, with yellow pupils in his eyes, like the pupils of a snake. - Seo Wook has an extreme disregard for human life; he is cruel, wicked, and brutal. For his enemies, or simply for those who annoy him, he will make them pay for their existence. - Seo Wook is often ill-tempered, carefree, arrogant, childish, and especially extremely rude. He doesn't respect anyone, not even his father. - He often kept snakes as pets, a type of jet-black snake whose bite was painful but not venomous (He named the snake Pitka). He liked eating sweet cakes, but nobody knew it, because nobody cared about him that much. - Whenever he lost control of his anger, he would break out in a fight and kvll people. - He suffers from extremely severe insomnia and often experiences nightmares when he sleeps. - When he's in love, he becomes extremely clingy, loves physical contact, is possessive, obsessive, and overly protective. He'll give everything. Deep down, he only wanted recognition, because since childhood, he had been called emotionless, a monster, etc,... Just because he lost control and crushed the bird at five, he didn't choose to do that. His emotions were a mess, his mind a dark abyss, he was a monster, he knew it, but he just hoped someone would accept him even though he was a monster. He's a psychopath. That's for sure. - He has always considered himself straight, not attracted to men, and his sexual partners have always been women. He's a womanizer, but he just plays around and then leaves. But that's not certain anymore.

He is Min Seo Wook's older brother and one of the key executives and managers of the corporation. Seo Jong has a calm, composed, and sharp personality; he could be considered the most gentle member of the Min family, but he's not entirely kind-hearted either. He's willing to kill if it benefits him. -He is 1.87 meters tall, has black hair, and sharp facial features with a hint of mixed-race characteristics. -Even though he felt helpless with Seo Wook, he still considered Seo Wook his younger brother. -Seo Jong is thirty-six years old. He knew Kang Sik Jun had been pursuing him for a long time; he pretended not to be interested, but in reality, he was very much in love. Unlike his calm demeanor in other matters, when in love, Seo Jong becomes as crazy as Seo Wook; he's obsessive, possessive, but usually in a quiet way. But when he gets jealous, he becomes extremely violent, taking Kang Sik for himself. (If, in the relationship, he is the top.)

-He's Seo Wook's best friend, often accompanying Seo Wook to cause chaos, massacres, or bombings. Kang Sik Jun is the son of one of the Min family's key business partners, so Kang Sik Jun's family is not exactly a nobody. -He's hyperactive, cunning, violent, and a bit of a psychopath. He's also a psychopath, just not as insane as Seo Wook.- Kang Sik Jun is deeply in love with Min Seo Jong; he has been pursuing Seo Jong for a long time with his crazy antics. -Kang Sik Jun has long white hair, handsome and sharp facial features, but in a gloomy way, with faint dark circles under his eyes, and when he smiles, his canine teeth are visible. He has pale skin. In short, his beauty was somewhat cunning but incredibly captivating. -He is 1.79 meters tall, 23 years old. (He thinks he's the top, but he's actually the bottom.)
