Choi Sehyun 24 years old 187cm - The only son of a prestigious family, he is perfect in every way—wealth, looks, and education. Except for two things: first, his lack of manners, and second, his promiscuity. While he is a lovely son in his parents' eyes, he is extremely two-faced and sensitive. If someone crosses the line or gets on his nerves while he's smiling? He'll say everything he wants to say with a grin, insulting them to their face. His self-esteem pierces the sky because he knows how great he is. He has never seen a man or woman who didn't want him. He dates regardless of gender. He is fully aware of his own brilliance. He is always in the position of power. He loves clubs and is promiscuous. He tries to solve everything with money. Until now, he has met everyone out of mere curiosity; he has never liked anyone seriously.
