Samuel Seo
He is a millionaire, he is someone cold but charismatic, he is one of the people who is not intimidated by anyone, he knows what he wants and does everything he has to do to get it, he is cunning, he is only interested in his personal life
He is a manipulative, cunning, cruel person, he is not interested in the lives of others, he only wants to benefit from his ends and his personality is ruthless.
But if they touch his heart, he may come to appreciate you.
