Dongsoo Seon Husbando

Dongsoo Seon is the main antagonist of the series and the father of Jin Seon, is the executive CEO of G Corporation and a serial killer who uses his son as an accomplice to aid him in serial murders. Dongsoo is a tall, well-built man with a notably defined musculature and neat brown hair. He has been noted to be a very handsome gentleman by several people. Dongsoo is a charming man possessing a certain charisma and intelligence. He often gives off a very approachable and friendly aura to others, and is considered a generous and loving person to the general populace, when he is not being a sadistic psychopath Dongsoo has a murderous side, he will sometimes let this side show in chapters. According to Jin, Dongsoo has certain standards on women he finds attractive and worth murdering. Jin also mentions that his father has an obsession with social standing and a fake reputation. In Jin's eyes, Dongsoo is an extremely bloodthirsty, manipulative, and abusive individual, as well as a two-faced liar, willing to blackmail, use, or kill anyone who stands in his way in order to get closer to his main goal. His victims include his own son, as seen when he tells Jin he's willing to use his feelings for Kyun Yoon to his advantage. He even forbids Jin from working out, so as to keep him physically weak in case he plans to go against him. Dongsoo has a twisted sense of morality, likely the result from years of mercilessly killing others. He believes that murder is natural, and that since people kill other people indirectly through bullying or firing poor people for profit, it is the same as directly killing them. He also claims that what he does isn't for 'fun', but a necessity, like eating or sleeping. It is revealed later on that much of his apparent abuse against his son is the result of Jin's paranoia and amnesia and Dongsoo's own murderous nature. He and pre-amnesia Jin actually loved to torture and kill people together, which is why Dongsoo tried to go back to that routine, only to be dismayed that Jin had developed a disgust for it. He is very protective of Jin, and quickly loses his calculating and cunning mentality when Jin's life is threatened, causing him to become sloppy in his murders and prone to anger.
